In a printer device that is provided with a determination means for determining the presence or absence of a match between the control code and the data signal, and a control means for controlling the presence or absence of an operation in accordance with the control code and the data signal according to the presence or absence of a match determined by the determination means, the content is different. A memory is provided in which the control code can be set variably.

The invention according to claim 2 has an interface into which a data signal with control codes added before and after is input, and determines whether or not the control code input from the interface matches the control code set in advance in the device. In the printer device, a plurality of types of control codes are set in advance in a printer device, which is provided with a determination means for determining whether or not the determination means matches, and a control means for controlling the presence or absence of an operation according to the control code and the data signal according to the presence or absence of a match determined by the determination means. A memory is provided, code type means for identifying the type of control code input from the interface, and data switching means for selecting from the memory a control code of the same type as the control code identified by the code type means.

In the invention according to claim 1, control codes having different contents are variably set in the memory, so that even control codes having different contents from the control codes set in advance in the device can be read by setting in the memory. This makes it possible to support multiple types of host computers.

In the invention as claimed in claim 2, a plurality of types of control codes are set in advance in the memory, a code type means identifies the type of control code inputted from the interface, and the code type means identifies the type of control code that is the same as the control code identified by the code type means. By selecting the type of control code from the memory by the data switching means, it is possible to read multiple types of control codes by switching the data switching means. be able to respond accordingly.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 4. First, in the label printer 1 of this embodiment, which is the printer device of the invention as claimed in claim 1, as illustrated in FIG.

OM (Read Only Memory) 3, R
AM (Random Access Memory
) 4, a printing mechanism 9 consisting of a backup RAM 5, which is a memory, a pulse motor 6, a thermal head 7, a sensor 8, etc., an I/F (Interface): l Citrol 10 is connected, and this I/F controller 10 A keyboard 12 and a host computer 13 are connected to the interface 11.

As illustrated in FIG. 3, the received data 14 transferred from the second host computer 13 to the label printer 1 of the present invention includes a start control code before the data signal 15 consisting of commands, print data, etc. is ESC16
, and later a control code for termination, LP0.
1 and NULL 8, and a control code having the same content as the control codes 16 to 18, etc., is set in advance in the backup RAM 5.

In such a configuration, the operation of this label printer 1 will be explained below based on the flowchart illustrated in FIG. First, this label printer 1 is preset to two operating modes, a setting mode and an online mode, and as illustrated in FIG. It is set to switch.

Therefore, it normally operates in online mode, and as illustrated in FIG. 1(b), when the received data 14 input from the host computer 13 via the interface 11 is read, ESC16, which is the control code for starting, and backup R
The presence or absence of a match with ESC16 set in AM5 is C.
Determined by PU2. Therefore, if they match, the CPU 2 determines whether or not the control code 17.18 for ending the received data 14 matches the control code 17.18 set in the backup RAM 5, and if these match, the reception The content of data signal 15 of data 14 is analyzed. Accordingly, the CPU 2 controls the printing mechanism 9 in accordance with the content of this analysis, thereby executing printing operations such as label issuance.

Here, in this label printer l, when the model of the host computer 13 is changed, for example, and the CPU 2 determines that there is a mismatch between the ESC 16 of the received data 14 and the ESC 16 set in the backup RAM 5, the received Data 14 is discarded.

In such a case, in this label printer 1,
The operation mode is switched to the setting mode by turning on and off the power of the main body, and necessary control codes are set by inputting operations on the keyboard 12 and stored in the backup RAM 5, as illustrated in FIG. 1(C).

By doing so, this label printer 1 can read even different types of control codes, so it can support multiple types of host computers 13 and the like.

In this embodiment, the label printer 1 is exemplified as being able to handle different types of control codes by inputting the control codes into the backup RAM 5 through operation input, but the present invention is not limited to the above method. According to the invention as claimed in claim 2, a plurality of types of control codes are set in advance in a memory such as a backup RAM, and the types of control codes of received data are identified and control codes of the same type are selected from the memory. It is also possible to implement such a printer device.

In this case, as illustrated in FIG. 4, if ESC and ( are set as two control codes), these control codes are sequentially compared with the control code of the received data,
The control codes of the matching type are read in sequence. In this way, even if the type of control code changes due to a change in the model of the host computer, the printer device automatically responds to the change, resulting in good versatility and operability.

Effects of the Invention The invention described in claim 1 has an interface into which a data signal with a control code added before and after is input, and it is possible to match the control code input from the interface with the control code set in advance in the device. In a printer device that is provided with a determination means for determining the presence or absence of a data signal, and a control means for controlling the presence or absence of an operation according to a control code and a data signal according to the presence or absence of a match determined by the determination means, control codes having different contents may be used. By providing a memory that can be set variably, it is possible to read control codes that are different from the control codes preset in the device by setting them in the memory, making it compatible with multiple types of host computers. This has the advantage of contributing to improving the versatility of printer devices with a simple structure.
