Here, the barcode recorded on the recording medium is an image that is supposed to be optically read later, and is read when it is optically read later by being recorded on the recording medium with high accuracy. To improve the success rate. In general, in a recording apparatus that records an image by a recording head while transporting a recording medium, an image is recorded at a slow recording speed due to the influence of vibrations generated during recording and other structural features related to recording. Compared with the case of recording an image at a higher recording speed, the image can be recorded with higher accuracy. Therefore, by executing the image recording at a lower recording speed, a barcode or the like can be recorded. Although it is possible to record a specific symbol image with high accuracy, there is a need not to make the time required for image recording as long as possible.

FIG. 2 is a diagram schematically illustrating an example of a coupon 5 issued by the recording system 1 according to the present embodiment.
In the present embodiment, the coupon 5 issued by the recording system 1 has two types: a barcode image as shown in FIG. 2 and a barcode image not recorded. ing.
The bar code recorded on the coupon 5 is an identification code for the host computer 10 to execute processing corresponding to the content of the coupon 5, for example, the content of the coupon 5 deducting a predetermined amount. If it is, the barcode of the coupon 5 is read by the barcode reader at the time of accounting, and when a signal to that effect is input to the host computer 10, the host computer 10 deducts a predetermined amount from the purchase amount. Execute the process.
In the coupon 5 shown as an example in FIG. 2, the top logo 40 is recorded on the top thereof. Below the top logo 40, a coupon information image 41 indicating the contents of the coupon 5 is recorded. Below the coupon information image 41, a barcode image 42, which is a barcode image corresponding to the coupon 5, is recorded.

Next, through the description of the operations of the POS application execution unit 20 and the printer driver execution unit 21 (recording control unit), the coupon 5 (coupon 5 on which the barcode image 42 is recorded) shown as an example in FIG. 2 is issued. The basic operation of the recording system 1 in this case will be described.
The POS application execution unit 20 generates recording information data including information relating to an image to be recorded on the coupon 5 by executing a POS application installed in the host computer 10 in advance, and outputs the recording information data to the printer driver execution unit 21. .
The recorded information data is data in which various types of information related to images are held in a format that can be analyzed by a printer driver execution unit 21 (described later) so that a predetermined image is appropriately recorded at a predetermined position of the coupon 5. That is.
Specifically, the recording information data related to the coupon 5 shown in FIG. 2 indicates data indicating an image to be recorded as the top logo 40 and a position where the top logo 40 should be recorded in the recordable area of the coupon 5. Data and data indicating the size of the top logo 40 are included.
The recorded information data includes data indicating the position where the coupon information image 41 should be recorded in the recordable area of the coupon 5 and data indicating the character string to be recorded in the coupon information image 41. Each character included in the character string is expressed as a predetermined character code.
Further, as in the coupon 5 of FIG. 2, the record information data related to the coupon 5 in which the barcode image 42 is recorded includes data indicating the position and size of the barcode image 42 in the recordable area of the coupon 5. , Data identifying the barcode to be recorded is included. In the data, the barcode is specified by a combination of a character string indicating the barcode and the type of barcode font. The barcode font is a font corresponding to various standards of barcode, and examples of the font include JAN8 (EAN), JAN13 (EAN), CODE39, CODE93, CODE128 (EAN), ITF, and CODEBAR. .

The printer driver execution unit 21 executes control commands corresponding to the command specifications of the printer 12 based on the recording information data input from the POS application execution unit 20 by executing a printer driver installed in the host computer 10 in advance. Generate and output to the printer-side control unit 30.
The control command is a command for causing the printer 12 to execute a series of processes related to the issuance of the coupon 5, and a command for causing the conveyance mechanism to convey the thermal roll paper, a command for driving the line thermal head 25, and a thermal mechanism for the cutting mechanism. A command for cutting the roll paper is included.
Here, the control command relating to the issuance of the coupon 5 shown in FIG. 2 includes at least a logo recording command for recording the top logo 40, a coupon information recording command for recording the coupon information image 41, and a barcode. Three commands, a barcode recording command for recording the image 42, are included. These recording commands are commands for driving the line thermal head 25 and the transport mechanism so that a predetermined image is recorded in a predetermined manner at a predetermined position.
In particular, the barcode recording command includes image data (for example, bitmap data) indicating the barcode image 42. The printer driver includes a program having a function of generating image data indicating a barcode based on a combination of a character string indicating the barcode and a barcode font type. Generates image data indicating the barcode image 42 based on the character string indicating the barcode and the type of barcode font included in the recording information data input from the POS application execution unit 20.

Each command included in the control command output from the printer driver execution unit 21 to the printer 12 is sequentially stored in the reception buffer 36 by the transmission / reception control unit 35.
The printer-side control unit 30 issues the coupon 5 by referring to the setting information data 37 stored in the printer-side storage unit 34 and sequentially reading and executing the control commands stored in the reception buffer 36. Execute.
The setting information data 37 is data in which setting information (setting values) relating to recording of the printer 12 is described.
The setting information related to recording refers to various settings related to image recording such as recording density and roll paper width of thermal roll paper. In particular, the setting information data 37 stores basic recording speed information 38 indicating a recording speed (described later).
When the control command is input, the printer-side control unit 30 refers to the setting information data 37 to issue the coupon 5 in a state in which various setting information described in the setting information data 37 is reflected when the coupon 5 is issued. Above, each part is controlled based on a control command, and the coupon 5 is issued. In particular, although details will be described later, the printer-side control unit 30 executes image recording at a speed that conforms to the recording speed indicated by the basic recording speed information 38.

By the way, the barcode recorded on the coupon 5 is an image assumed to be optically read later by an optical reading device such as a barcode reader. Therefore, it is required to improve the success rate of optical reading by being recorded on the coupon 5 with high accuracy.
The coupon 5 is handed over to the customer at the store cash register. Therefore, the customer who receives the coupon 5 needs to wait until the issue of the coupon 5 is completed. For this reason, there is a need to reduce as much as possible the time required for the processing related to the issue of the coupon 5, in particular, the processing related to the recording of the image on the thermal roll paper performed when the coupon 5 is issued.
Based on the above, the recording system 1 according to the present embodiment performs the following operations.

FIG. 3 is a diagram illustrating an example of a user interface provided by the printer driver execution unit 21. The user interface shown in FIG. 3 is displayed on the display panel 16a using a GUI environment provided by a predetermined OS.
FIG. 3A shows a basic recording speed input window 50 which is a user interface for inputting a basic recording speed.
The recording speed is the speed of operation when the printer 12 records an image on the thermal roll paper. In the printer 12 according to the present embodiment, the driving speed of the line thermal head 25 (the cycle of the timing at which the heating elements of the line thermal head 25 are driven), and the mechanism and apparatus that operate in association with the driving of the line thermal head 25 The operation speed is variable, and the recording speed can be adjusted accordingly. For the same image, the faster the recording speed, the shorter the time required to record the image, while the slower the recording speed, the longer the time required to record the image.
The basic recording speed is a reference recording speed when issuing the coupon 5, and the printer 12 records an image at a speed conforming to the set basic recording speed, except for an exception described later. Execute.

As described above, the printer 12 includes the line thermal head 25. In the line thermal head 25, a plurality of heating elements are arranged in a line in accordance with a predetermined resolution. The recording of the image on the heat-sensitive roll paper is executed when each heat generating element appropriately generates heat at a predetermined timing by energization, and the pixels are formed on the heat-sensitive roll paper along with the heat generation.
Here, the heating element is in a heating state (a state where the temperature of the heating element is higher than a predetermined temperature and pixels can be formed on the thermal roll paper) and a non-heating state (a state of the heating element) depending on whether or not power is supplied. The temperature is lower than a predetermined temperature and the pixel is formed on the heat-sensitive roll paper), but the shorter the drive timing cycle of the heating element, The higher the recording speed, the greater the possibility that the transition between the heat generation state and the non-heat generation state will not be smoothly performed, and accordingly, unevenness of the image formed on the heat-sensitive roll paper or unnecessary The possibility of pixel formation, dot dropping, etc. increases. Further, when the recording speed is high, it can be said that the generated vibration is larger than when the recording speed is slow. Due to the magnitude of this vibration, when the recording speed is high, the recorded image is relatively Can be said to have low accuracy (low image reproducibility). That is, the faster the recording speed, the lower the accuracy of the recorded image, while the slower the recording speed, the higher the accuracy of the recorded image.

In the basic recording speed input window 50 shown in FIG. 3A, the user can set the basic recording speed.
Specifically, in the present embodiment, the recording speed is divided into 13 stages according to the speed, and the user can select 1 of the recording speeds divided into 13 stages in the basic recording speed input window 50. The basic recording speed can be set by selecting the recording speed at this stage.
3A, the basic recording speed input window 50 includes 13 items from “1st” (fastest recording speed) to “13th” (slowest recording speed) in the window. It is displayed, and the cursor can be positioned exclusively on any one of these 13 items.
Then, the user sets the basic recording speed by clicking the OK button 51 after placing the cursor on the item corresponding to the recording speed that the user wants to set as the basic recording speed.

The basic recording speed set by the user using the basic recording speed input window 50 is reflected in the basic recording speed information 38 of the setting information data 37 stored in the printer-side storage unit 34 of the printer 12 as follows. The basic recording speed information 38 is used as follows when recording an image.
That is, when the user sets the basic recording speed using the basic recording speed input window 50, the printer driver execution unit 21 indicates that the basic recording speed information 38 of the setting information data 37 stored in the printer-side storage unit 34 is A command for executing a process for rewriting the content of the basic recording speed information 38 is generated so as to be information indicating the basic recording speed set by the step, and is output to the printer-side control unit 30.
The printer-side control unit 30 to which the command is input controls the printer-side storage unit 34 so that the basic recording speed information 38 of the setting information data 37 becomes information indicating the basic recording speed set by the user. The contents of the basic recording speed information 38 are rewritten.
After the contents of the basic recording speed information 38 of the setting information data 37 are rewritten, the printer-side control unit 30 records the basic recording speed of the setting information data 37 when recording an image on the thermal roll paper with the issuance of the coupon 5. With reference to the information 38, image recording is executed at a speed based on the recording speed indicated by the basic recording speed information 38.
In FIG. 3A, the item “according to printer settings” can be selected. When this item is selected, the content of the basic recording speed information 38 of the setting information data 37 is not rewritten, and an image is recorded that conforms to the recording speed indicated by the current basic recording speed information 38.
As described above, in the present embodiment, one recording speed can be set as the basic recording speed among the recording speeds divided into 13 stages according to the speed. Basically, the user sets the basic recording speed so that the time required for recording can be shortened as much as possible in consideration of the balance between the accuracy of the image and the waiting time of the customer.

FIG. 3B shows a barcode recording speed input window 53 which is a user interface for setting a recording speed when issuing the coupon 5 on which the barcode is recorded. Hereinafter, for convenience of explanation, the recording speed when issuing the coupon 5 on which the barcode is recorded is referred to as “barcode recording speed”.
As described above, since the barcode image 42 is an image that is supposed to be optically read, the image is recorded with a certain degree of accuracy, and thus can be optically read with high accuracy. It is required to be. Therefore, with respect to the barcode image 42, priority is given to high image accuracy over short time required for image recording.
Based on this, although details will be described later, in this embodiment, it is possible to record an image at a different recording speed by using the coupon 5 in which the barcode image 42 is recorded and the coupon 5 in which the barcode image 42 is not recorded. For example, for the coupon 5 in which the barcode image 42 is not recorded, the image is recorded at the highest possible recording speed, while for the coupon 5 in which the barcode image 42 is recorded, the recording speed is decreased. By recording an image, the barcode image 42 can be recorded with high accuracy.

The barcode recording speed input window 53 is a user interface for setting a recording speed (barcode recording speed) applied when issuing the coupon 5 on which the barcode image 42 is recorded.
The user can set the barcode recording speed by selecting one recording speed from among 13 recording speeds according to the speed using the barcode recording speed input window 53. is there. The method for setting the bar code recording speed is the same as the method for setting the basic recording speed in the basic recording speed input window 50 described above.
When the user sets the bar code recording speed using the bar code recording speed input window 53, the bar code recording speed is set so that at least the bar code image 42 is optically read later with high accuracy. Set the speed to be recorded in 5. Thereby, it can prevent that the recording speed of the coupon 5 in which the barcode image 42 is recorded becomes unnecessarily slow. As described above, as a result of setting the barcode recording speed by the user, basically, the barcode recording speed is set slower than the basic recording speed. This is because the coupon 5 that does not include the barcode image 42 does not need to be optically read, and relatively shortening the time required to issue the coupon 5 is regarded as important.
When the barcode recording speed is input through the barcode recording speed input window 53, the content of the input is reflected in the barcode recording speed information 39 of the setting information data 37 of the printer-side storage unit 34 of the printer 12 as follows. Is done.
That is, when the user inputs the barcode recording speed using the barcode recording speed input window 53, the printer driver execution unit 21 reads the barcode of the setting information data 37 stored in the printer-side storage unit 34 of the printer 12. A command for executing processing for rewriting the contents of the barcode recording speed information 39 is generated and output to the printer-side control unit 30 so that the recording speed information 39 becomes information indicating the barcode recording speed set by the user. To do.
The printer-side control unit 30 to which the command is input controls the printer-side storage unit 34 so that the barcode recording speed information 39 of the setting information data 37 becomes information indicating the barcode recording speed set by the user. Then, the contents of the bar code recording speed information 39 are rewritten.
A mode of using the bar code recording speed information 39 will be described later.

Next, the operation of the host computer 10 when issuing the coupon 5 will be described using the flowchart of FIG.
As a premise of the flowchart of FIG. 4, it is assumed that the record information data related to the coupon 5 to be issued is generated by the POS application execution unit 20.
Further, when issuing the coupon 5, the user uses the basic recording speed input window 50 and the bar code recording speed input window 53 by the function of the printer driver, and both the basic recording speed and the bar code recording speed. Shall be set.

First, according to the basic recording speed setting using the basic recording speed input window 50 by the user, the printer driver execution unit 21 of the control unit 15 of the host computer 10 acquires information indicating the basic recording speed set by the user. (Step SA1).
Next, the printer driver execution unit 21 sets the basic recording speed information 38 included in the setting information data 37 stored in the printer storage unit 34 based on the information indicating the basic recording speed acquired in step SA1 by the user. A command for executing a process of rewriting the contents of the basic recording speed information 38 (hereinafter referred to as “basic recording speed information rewriting command”) is generated and output to the printer 12 so as to be information indicating the basic recording speed. (Step SA2).
As described above, the printer-side control unit 30 to which the basic recording speed information rewrite command is input makes the basic recording speed information 38 become information indicating the basic recording speed set by the user based on the command. The contents of the basic recording speed information 38 are rewritten.
Next, in response to the setting of the barcode recording speed using the barcode recording speed input window 53 by the user, the printer driver execution unit 21 acquires information indicating the barcode recording speed set by the user (step SA3). .

Next, the printer driver execution unit 21 determines that the barcode recording speed information 39 included in the setting information data 37 stored in the printer-side storage unit 34 is based on the information indicating the barcode recording speed acquired in step SA3. A command for executing a process of rewriting the content of the barcode recording speed information 39 (hereinafter referred to as “barcode recording speed information rewriting command”) so as to be information indicating the barcode recording speed set by Output to the printer 12 (step SA4).
As described above, the printer-side control unit 30 to which the bar code recording speed information rewrite command is input, the bar code recording speed information 39 based on the command includes information indicating the bar code recording speed set by the user. Thus, the contents of the bar code recording speed information 39 are rewritten.

Next, the printer driver execution unit 21 acquires the recording information data generated by the POS application execution unit 20 (step SA5).
Next, the printer driver execution unit 21 analyzes the acquired recording information data and determines whether or not the barcode image 42 is included in the image to be recorded on the coupon 5 (step SA6).
As described above, in the recording information data, since the barcode is specified by a combination of the character string indicating the barcode and the type of the barcode font, the printer driver execution unit 21 adds the recording information data to the recording information data. An image to be recorded in the coupon 5 includes the barcode image 42 by determining whether or not the data indicating the combination of the character string indicating the barcode and the barcode font type is included. It is determined whether or not.
When the barcode image 42 is included in the image to be recorded in the coupon 5 (step SA6: YES), the printer driver execution unit 21 corresponds to the case where the barcode image 42 is included in the image to be recorded. A control command is generated and output to the printer 12 (step SA7). On the other hand, when the barcode image 42 is not included in the image to be recorded on the coupon 5 (step SA6: NO), the printer driver execution unit 21 determines that the image to be recorded does not include the barcode image 42. A corresponding control command is generated and output to the printer 12 (step SA8).
Hereinafter, the operations of Step SA7 and Step SA8 will be described in detail.

FIG. 5 is a diagram showing the contents of the control command. FIG. 5A shows a case where the barcode image 42 is included in the control command generated by the process of step SA7, that is, the image to be recorded in the coupon 5. Shows the contents of the control command generated, and (B) is generated when the bar code image 42 is not included in the control command generated by the process of step SA8, that is, the image to be recorded in the coupon 5. Shows the contents of the control command.
When the barcode image 42 is not included in the image to be recorded on the coupon 5, only the top logo 40 and the coupon information image 41 are recorded on the coupon 5.
FIG. 5 shows only the commands related to image recording, specifically, the logo recording command, the coupon information recording command, and the barcode recording command described above as control commands. In addition, the control command includes a command for conveying the thermal roll paper, a command for cutting the thermal roll paper by a cutting mechanism, and the like.

As shown in FIG. 5A, when the barcode image 42 is included in the image to be recorded on the coupon 5 (step SA6: YES), the printer driver execution unit 21 precedes the command related to image recording. The speed adjustment command is generated and output (step SA7).
The speed adjustment command refers to the bar code recording speed information 39 instead of the basic recording speed information 38 of the setting information data 37 when recording an image related to the coupon 5, and conforms to the recording speed indicated by the bar code recording speed information 39. This command instructs to record an image at a specified speed.
When the speed adjustment command is input, the printer-side control unit 30 transfers the reference information from the basic recording speed information 38 to the bar code recording speed information 39 regarding the recording speed among the various setting information held in the setting information data 37. The subsequent image recording on the coupon 5 (coupon 5 on which the barcode image 42 is recorded) is executed at a speed based on the recording speed indicated by the barcode recording speed information 39.
As shown in FIG. 5A, the printer driver execution unit 21 sequentially generates and outputs a logo recording command, a coupon information recording command, and a barcode recording command following the speed adjustment command. When various images are recorded in accordance with these commands, image recording is executed at a speed based on the recording speed indicated by the bar code recording speed information 39. As described above, the recording speed indicated by the bar code recording speed information 39 is such that at least the bar code image 42 is recorded on the coupon 5 in a state where it is optically read later with high accuracy. Since it is set, the barcode image 42 recorded on the issued coupon 5 is recorded with high accuracy and can be optically read with high accuracy.

On the other hand, as shown in FIG. 5B, when the barcode image 42 is not included in the image to be recorded on the coupon 5 (step SA6: NO), the printer driver execution unit 21 outputs a speed adjustment command. The logo recording command and the coupon information recording command are sequentially generated and output (step SA8).
In this case, when recording the top logo 40 and the coupon information image 41, the printer-side control unit 30 refers to the basic recording speed information 38 of the setting information data 37 and conforms to the recording speed indicated by the basic recording speed information 38. Record images at speed. As described above, the user sets the basic recording speed so that the time required for recording can be shortened as much as possible in consideration of the balance between image recording accuracy and customer standby time. Therefore, for the coupon 5 (the coupon 5 in which the barcode image 42 is not recorded), the coupon 5 can be issued after shortening the time required for the issue.

Next, referring to the flowchart of FIG. 6, the operation of the printer 12 that has received the control command shown in FIG. 5A, that is, the control command corresponding to the case where the barcode image 42 is included in the image recorded on the coupon 5. Will be described. In the following description, processes other than the process related to image recording, such as the process of transporting the thermal roll paper and the process of cutting the thermal roll paper, are omitted.
The printer-side control unit 30 of the printer 12 reads the speed adjustment command included in the control command (step SB1).
Next, the printer-side control unit 30 switches the reference information regarding the recording speed from the basic recording speed information 38 to the barcode recording speed information 39 (step SB2).
Next, the printer-side control unit 30 records the top logo 40 at a speed based on the recording speed indicated by the barcode recording speed information 39 based on the logo recording command input from the host computer 10 (step SB3).
Next, the printer-side controller 30 records the coupon information image 41 at a speed based on the recording speed indicated by the barcode recording speed information 39 based on the coupon information recording command input from the host computer 10 (step SB4). ).
Next, the printer-side control unit 30 records the barcode image 42 at a speed based on the recording speed indicated by the barcode recording speed information 39 based on the barcode recording command input from the host computer 10 (step SB5). ).
As described above, for the coupon 5 in which the barcode image 42 is included in the recorded image, the image recording is executed at a speed based on the recording speed indicated by the barcode recording speed information 39, and thereby the barcode image 42 is recorded. However, the optical reading can be performed with high accuracy.

As described above, the printer driver execution unit 21 of the host computer 10 according to the present embodiment depends on whether the image to be recorded by the printer 12 includes the barcode image 42 (predetermined symbol image). Then, the image is recorded on the printer 12 by changing the recording speed.
According to this, the printer driver execution unit 21 changes the recording speed depending on whether or not the barcode image 42 is included in the image to be recorded on the thermal roll paper as the recording medium, and displays the image on the printer 12. Since the image can be recorded, the image including the barcode image 42 is recorded at a low recording speed, and thus the image can be recorded with high accuracy. Further, when the barcode image 42 is not included, it is possible to execute the image recording without reducing the recording speed, so that it is possible to suppress the time required for the recording from being prolonged.

In addition, the host computer 10 according to the present embodiment includes a POS application execution unit 20 that generates recording information data including information relating to an image to be recorded on the thermal roll paper by executing the POS application. Then, the printer driver execution unit 21 determines whether the recording information data generated by the POS application execution unit 20 includes data indicating a combination of a character string indicating a barcode and a barcode font type. Then, a control command (speed adjustment command) for changing the recording speed is generated and output to the printer 12.
According to this, the printer driver execution unit 21 sets the recording speed according to whether or not the recording information data includes data indicating a combination of a character string indicating a barcode and a barcode font type. In order to generate a control command to be changed and output it to the printer 12, the printer 12 changes the recording speed based on the input control command and changes the recording speed to determine whether the image is included. Can be recorded.
In addition, by setting a control program and a communication protocol so that the above control commands can be exchanged between the host computer 10 and the printer 12, the host computer 10 utilizes the control commands, The recording speed can be changed easily.

In the present embodiment, a barcode recording speed input window 53, which is a user interface capable of inputting a recording speed when an image including the barcode image 42 is recorded, can be displayed on the display panel 16a by the function of the printer driver. is there. When the barcode driver 42 includes the barcode image 42 in the image to be recorded on the coupon 5, the printer driver execution unit 21 determines that the recording speed when recording the image related to the coupon 5 is the barcode recording speed. The printer 12 is caused to record an image by changing the recording speed so that the recording speed is set using the input window 53.
According to this, the user can easily set the recording speed for recording an image including the barcode image 42 by using the barcode recording speed input window 53 as a user interface. Further, the image recording can be executed by changing the recording speed when recording the barcode image 42 according to the setting by the user.

Second Embodiment
Next, a second embodiment will be described.
The recording system 1 according to the first embodiment described above has a configuration in which the user sets the barcode recording speed. On the other hand, in the recording system 1 according to the present embodiment, it is not necessary for the user to set the barcode recording setting. For the coupon 5 on which the barcode image 42 is recorded, an appropriate recording speed is automatically calculated. Thus, image recording is executed in accordance with the calculated recording speed.
Due to such a configuration, the printer driver does not have a function of displaying the bar code recording speed input window 53 that is a user interface for the user to input the bar code recording speed. There is no need to input the bar code recording speed explicitly using the code recording speed input window 53. As a result, the ease of development of the printer driver and the convenience of the user are improved.

FIG. 7 is a flowchart showing the operation of the host computer 10 according to the present embodiment.
FIG. 7 shows the operation of the host computer 10 when issuing one coupon 5, and the recording information data related to the coupon 5 has already been generated by the POS application execution unit 20 at the start of the operation. Shall.
The printer driver execution unit 21 of the host computer 10 acquires the recording information data generated by the POS application execution unit 20 (step SC1).
Next, the printer driver execution unit 21 determines whether or not the barcode information 42 is included in the image to be recorded on the coupon 5 by determining whether or not the data related to the barcode is included in the recording information data. Is determined (step SC2).
When the barcode image 42 is not included (step SC2: NO), the printer driver execution unit 21 generates a control command corresponding to the case where the barcode image 42 is not included in the image to be recorded on the coupon 5. And output to the printer 12 (step SC3). Since the operation of step SC3 is the same as the operation of step SA8 in FIG. 4, detailed description thereof is omitted, but in step SC3, each image recorded on the coupon 5 is indicated by the basic recording speed information 38. Recorded according to the recording speed. That is, in order to shorten the waiting time of the customer, the image is recorded according to the recording speed set as fast as possible in consideration of the balance with the accuracy of the recorded image.

On the other hand, when the barcode image 42 is included in the image to be recorded in the coupon 5 (step SC2: YES), the printer driver execution unit 21 calculates the optimum recording speed for recording the barcode image 42. (Step SC4).
Here, the feature and tendency of the barcode shape differ depending on the barcode font, and the accuracy (required image reproducibility) required for image recording differs depending on the size of the barcode image 42. Based on this, a program having an algorithm for calculating the optimum recording speed based on the barcode font and the size of the barcode image 42 has been developed through experiments and simulations in advance and incorporated in the printer driver. The printer driver execution unit 21 calculates the recording speed based on the algorithm.
Next, based on the information indicating the recording speed calculated in step SC4, the printer driver execution unit 21 obtains the barcode recording speed information 39 included in the setting information data 37 stored in the printer-side storage unit 34 in step SC4. A command for executing a process of rewriting the contents of the barcode recording speed information 39 is generated so as to be information indicating the calculated recording speed, and is output to the printer 12 (step SC5). The printer-side control unit 30 of the printer 12 rewrites the content of the barcode recording speed information 39 based on the command.
Next, the printer driver execution unit 21 generates a control command corresponding to the case where the barcode image 42 is included in the image to be recorded in the coupon 5, and outputs the control command to the printer 12 (step SC6). Since the operation in step SC6 is the same as the operation in step SA7 in FIG. 4, detailed description thereof is omitted, but in step SC6, each of the images recorded on the coupon 5 has the bar code recording speed information 39. Recording is performed according to the recording speed shown. That is, the barcode image 42 is recorded with high accuracy, and thereby the barcode image 42 is recorded at an optimum recording speed calculated from the viewpoint of having a high reading accuracy.

As described above, it is possible to record an image with higher accuracy when the recording speed is slower than when the recording speed is faster. Therefore, only when the recording speed calculated in step SC4 is a value slower than the basic recording speed, both the recording of the barcode image 42 with high accuracy and the suppression of the lengthening of the time required for the recording are both performed. Can be realized.
Based on this, in step SC4, the printer driver execution unit 21 compares the calculated recording speed with the basic recording speed, and if the calculated recording speed is higher than the basic recording speed, the barcode recording speed is set. The value may be the same value as the basic recording speed instead of the calculated recording speed.
In this case, when the basic recording speed is higher than the recording speed at which the barcode image 42 can be properly recorded, the printer driver execution unit 21 records the image on the coupon 5 on which the barcode image 42 is recorded. By making the recording speed slower than the recording speed when the image is recorded on the coupon 5 where the barcode image 42 is not recorded, the recording accuracy of the barcode image 42 is improved.

As described above, in this embodiment, the printer driver execution unit 21 records an image including at least the barcode image 42 when the image to be recorded by the printer 12 includes the barcode image 42. The recording speed is changed so that the recording speed is suitable for recording the barcode image 42, and the printer 12 records the image.
As a result, the coupon 5 including the barcode image 42 can be recorded at a recording speed suitable for recording the barcode image 42. Further, for the coupon 5 that does not include the barcode image 42, since the image is not recorded at a lower recording speed, it is possible to suppress an increase in the time required for recording.

In the present embodiment, the barcode image 42 is an image that is supposed to be optically read, and the printer driver execution unit 21 records an image on the coupon 5 in which the barcode image 42 is recorded. The recording speed at the time of making is made slower than the recording speed at the time of recording an image with respect to the coupon 5 in which the barcode image 42 is not recorded.
According to this, it is possible to record with high accuracy by recording the barcode image 42 assumed to be optically read at a low recording speed.

<Third Embodiment>
Next, the recording system 1 according to the third embodiment will be described.
In this embodiment, the recording system 1 according to the first embodiment is different from the operation in step SA7 in FIG.
Hereinafter, the operation in step SA7 of FIG. 4 of the host computer 10 according to the present embodiment will be described in detail.

FIG. 8 is a diagram schematically showing the contents of the control command generated in step SA7 by the printer driver execution unit 21 of the host computer 10 according to the present embodiment.
In step SA7, the printer driver execution unit 21 according to the first embodiment described above records the coupon 5 by outputting a speed adjustment command prior to the logo recording command, the coupon information recording command, and the barcode recording command. All of the images to be recorded are recorded in accordance with the recording speed indicated by the barcode recording speed information 39, thereby improving the accuracy of the barcode image 42. On the other hand, in this embodiment, the top logo 40 and the coupon information image 41 are recorded according to the basic recording speed, while only the barcode image 42 is recorded according to the barcode recording speed. By recording an image, the time required for recording the image is shortened. Note that, as described above, the basic recording speed is higher than the barcode recording speed from the viewpoint of suppressing the time required for image recording and realizing the recording of the barcode image 42 with high accuracy. Is set faster than.

Referring to FIG. 8, in step SA7, the printer driver execution unit 21 outputs a logo recording command and a coupon information recording command without outputting a speed adjustment command. Thereby, for the top logo 40 and the coupon information image 41, the printer-side control unit 30 refers to the basic recording speed information 38 of the setting information data 37, and the speed according to the recording speed indicated by the basic recording speed information 38. The image recording is executed.
Then, after outputting the coupon information recording command, the printer driver execution unit 21 outputs a temporary speed adjustment command, and outputs a barcode recording command following the temporary speed adjustment command.
The temporary speed adjustment command is temporarily indicated by the bar code recording speed information 39 by referring to the bar code recording speed information 39 when recording an image based on a recording command output following the command. This command instructs to record an image at a speed according to the recording speed. Accordingly, when a barcode recording command is output following the temporary speed adjustment command, the printer-side control unit 30 uses the basic recording speed information 38 when recording the barcode image 42 based on the barcode recording command. Instead, the barcode recording speed information 39 is referred to, and an image is recorded at a speed based on the recording speed indicated by the barcode recording speed information 39.

  As described above, in this embodiment, only the recording of the barcode image 42 based on the barcode recording command is recorded based on the barcode recording speed using the temporary speed adjustment command. It is possible to prevent images other than 42 from being recorded in accordance with an unnecessarily slow recording speed, and to further reduce the time required for recording.

  Furthermore, in the present embodiment, the following processing is performed to effectively prevent unevenness in the image recorded on the coupon 5.

FIG. 9 is a diagram schematically illustrating another example of the coupon 5.
The recording of the image on the coupon 5 is executed while the thermal roll paper is moved in the transport direction (arrow Y1) and the line thermal head 25 is relatively moved in the direction of arrow Y2. The line thermal head 25 extends in the entire width direction of the thermal roll paper, and pixels are formed by the line thermal head 25 in units of rows extending in a line in the width direction. For example, each of the pixels included in the row G <b> 1 is simultaneously formed by each of the heating elements arranged extending in the width direction in the line thermal head 25.
In the coupon 5 shown in FIG. 9, a bottom logo 55 is recorded on the left side of the barcode image 42.
In the bottom logo 55, the end portion RT on the direction side indicated by the arrow Y1 in the transport direction is present on the transport direction side with respect to the end portion BT on the side indicated by the arrow Y1 in the barcode image 42, and is opposite to the transport direction The end portion RB on the direction side indicated by the arrow Y2 is present on the direction side indicated by the arrow Y2 with respect to the end portion BB on the direction side indicated by the arrow Y2 of the barcode image 42.

  When the image corresponding to the region A between the end portion RT and the end portion RB is recorded in the coupon 5 among the images shown in FIG. 9, in the present embodiment, the printer driver execution unit 21 displays the image corresponding to the region A. A control command for generating image data (for example, bitmap data) of the bottom logo 55 and the barcode image 42 and recording the image data (hereinafter referred to as “area A recording command”). And output to the printer 12. The printer-side control unit 30 to which the area A recording command is input records an image corresponding to the area A of the coupon 5 based on the image data indicating the area A.

Here, basically, the barcode recording speed is set slower than the basic recording speed. Therefore, if the image recording conforming to the barcode recording speed is reduced as much as possible and the image is recorded conforming to the basic recording speed, the time required for image recording can be shortened.
From this point of view, the area A is divided into an area a1, an area a2, and an area a3. For the area a1 and the area a3, an image is recorded in accordance with the basic recording speed, and for the area a2, If the image is recorded according to the barcode recording speed, the accuracy of the barcode image 42 is improved and the time required for image recording is shortened most efficiently and maximally. Can be achieved.
However, in this case, the recording speed of the bottom logo 55 is different in each of the areas a1 to a3. As the recording speed changes, unevenness occurs at the boundary between the areas. Image quality may be degraded.
Based on this, in the present embodiment, the printer driver execution unit 21 has an image that overlaps in the width direction of the barcode image 42, in other words, the barcode image 42 when forming pixels by the line thermal head 25. For an image including pixels that are formed in parallel with the pixels that form the image, the printer 12 is controlled so that the entire area of the image is recorded at a constant recording speed in accordance with the barcode recording speed.
In the example of FIG. 9, when the printer 12 records an image corresponding to the area A, the printer driver execution unit 21 divides the area A into areas a1-a3 for the purpose of shortening the time required for recording. Instead of generating a control command for recording the image of each area in accordance with a different recording speed, the printer generates a control command for recording the entire area A in accordance with a certain barcode recording speed. 12 is output. As a result, the entire area of the bottom logo 55 is recorded in accordance with a constant recording speed, and the deterioration of the image quality of the bottom logo 55 can be effectively prevented.

As described above, in the present embodiment, the printer driver execution unit 21 causes the printer 12 to change at least the recording speed when recording the barcode image 42.
According to this, it becomes possible to record only the barcode image 42 at a lower recording speed, and it is possible to effectively suppress an increase in the time required for recording accompanying a decrease in the recording speed.

Further, in the present embodiment, the printer driver execution unit 21 performs the barcode image 42 and other images recorded in parallel with the barcode image 42 by the line thermal head 25, with the barcode image 42, In addition, the printer 12 is controlled so that all areas of other images are recorded at a constant recording speed.
According to this, for other images recorded in parallel with the predetermined symbol image by the line thermal head 25, the entire area is recorded at a constant recording speed without changing the recording speed in the middle. Further, it is possible to effectively prevent the occurrence of unevenness due to the change in the recording speed in the middle.

The above-described embodiment is merely an aspect of the present invention, and can be arbitrarily modified and applied within the scope of the present invention.
For example, in the above-described embodiment, the invention has been described by taking an example in which an image is recorded on the thermal roll paper and the coupon 5 is issued. However, the present invention is not limited thereto, and other forms such as receipts are issued. The present invention is also applicable when recording an image on another recording medium such as cut paper. That is, the present invention can be widely applied to recording symbol images that are required to be recorded with high accuracy even when the recording speed is lowered.
In the present embodiment, the invention has been described by taking the barcode image 42 related to the one-dimensional barcode as an example of the symbol image. However, the symbol image is not limited to the one-dimensional barcode, but may be a two-dimensional barcode. For example, it may be a character string that is supposed to be recognized as an optical character. That is, the symbol image may be an image that is required to be recorded with high accuracy even when the recording speed is lowered.
In the present embodiment, the line printer has been described as an example. However, the present invention can also be applied to a serial printer, and is not limited to a thermal printer, and is not limited to an inkjet printer, a dot impact printer, or the like. The present invention can also be applied to printers of a type.
For example, with reference to FIG. 9, it is assumed that the recording head is an ink jet printer that records an image while scanning in the width direction. In this case, the printer driver execution unit 21 controls the printer 12 so as to record the image at a lower scanning speed of the recording head in the region corresponding to the barcode region x, so that the barcode image 42 is highly accurate. The time required for recording can be shortened while recording. That is, the present invention can be widely applied to a recording apparatus having a correlation between the recording speed and the accuracy of an image to be recorded, a control apparatus that controls the recording apparatus, and a system including these recording apparatus and control apparatus. .
