When a is operated (step S1), the print data of the page whose printing has already been started is transferred from the print data storage unit 50a to the printing unit 70, and the printing unit 70 prints this page (step S2). ). Even if printing is stopped, this portion is printed as it is. On the other hand, the transfer of the remaining print data stored in the print data storage unit 50a is stopped, and the print data waits (step S3). Then, the print data stored in the print data storage unit 50a is deleted by the storage data deletion unit 412 (step S4).

As described above, even if the print data already stored in the print data storage unit 50a is deleted by the storage data deletion unit 412, the print stop processing is not complete by itself. This is because reception of print data may not be completed. Therefore, it is necessary to perform a process of discarding the print data continuously received by the receiving unit 20.

FIG. 4 is a flowchart of the received data discarding process in the print canceling process. Print stop operation key 60
When “a” is operated (step S11), it is determined whether or not the reception of the print data of the print job is completed based on the detection result of the job end instruction of the job instruction detection unit 400a (step S12). If it is determined that the reception of the print data has been completed, the process ends. On the other hand, if it is determined that the reception of the print data has not been completed, the reception data discarding unit 411 starts the reception data discarding process (step S13).

The receiving section 20 receives the print data one byte at a time. When the 1-byte print data is received by the receiving unit 20 (step S14), the received print data is analyzed by the job command detecting unit 400a, and it is determined whether the received print data is a job end command (step S15). If it is determined that the print data is not a job end command, the print data is discarded (step S16). As a result, the received print data is stored in the print data storage unit 5.
It is not stored in 0a. Then, step S14
Then, the next 1-byte print data is received by the receiving unit 20. On the other hand, if it is determined that the print data is a job end command, the print data discarding process ends.

FIG. 5 is a flowchart of the print stop information output process. In the print stop information output unit 413, when the print stop operation key 60a is operated (step S21), it is determined whether the reception of the print data of the print job is completed based on the detection result of the job end instruction of the job instruction detection unit 400a. It is determined whether or not it is (step S22). If it is determined that the reception of the print data has been completed, the print data stored in the print data storage unit 50a is deleted by the storage data deletion unit 412 (step S2).
3) Information indicating that the printing process has been stopped is output to the printing unit 70, and the printing unit 70 prints out the information. (Step S24). Next, the print waiting state of the print data storage unit 50a is released (step S25), and the process ends.

On the other hand, if it is determined in step S22 that the reception of the print data has not been completed, the print data stored in the print data storage unit 50a is deleted by the storage data deletion unit 412 (step S26). When the print data received by the receiving unit 20 is discarded by the received data discarding unit 411 (step S27), step S24 is performed.
Proceed to.

<Effects> As described above, according to the first embodiment, when the print stop operation key 60a is operated, the print data stored in the print data storage unit 50a is deleted by the storage data deletion unit 412 and If the reception of the print data is not completed, the job instruction detecting unit 400
Until the job end command is detected by a, the received data discarding unit 411 discards the print data received by the receiving unit 20. Therefore, it is possible to stop the printing process and eliminate waste of printing.

In the received data discarding section 411, when the job command detecting section 400a detects the job end command, the print data discarding process is completed. Therefore, the other print data following the discarded print data can be received and printed normally without breaking the command sequence.

As a method of executing the print stop processing, when the print stop operation key 60a is operated, and when the reception of the print data is not completed, all the print data of the print job is received and the print data storage unit It is also conceivable that the print data stored in the storage 50a is erased collectively. However, in this case, it is necessary to wait until the job instruction detection unit 400a stores the job end instruction. On the other hand, in the printer according to the first embodiment, the print data received by the receiving unit 20 can be discarded without being stored in the print data storage unit 50a, so that the print data can be received at high speed and discarded. it can.

The print stop information output unit 413 outputs information indicating that printing has been stopped, and the print unit 70 prints the information. Therefore, it is possible to reliably notify the operator that the printing has been stopped.

In the first embodiment, the job instruction detecting unit 4
When a job end command is detected by 00a, the received data discarding unit 411 terminates the received data discarding process. However, when an instruction to stop printing is executed by the computer 110, the tail side of the print data of the print job is erased, the print data is transmitted only halfway, and the job end instruction of the print job is sent to the job instruction detecting unit 400a. May not be detected. In this case, when the job command detection unit 400a detects a job start command of another print data, the reception data discarding process of the reception data discarding unit 441 may be ended.

You. Then, the print data is transmitted to the printer device 210 by the printer driver 11.

In the printer apparatus 220, when the job start command received by the receiver 20 is detected by the job command detector 400a, the start of the print job is recognized. Thereafter, the control unit 30 analyzes the print data received subsequent to the reception unit 20 until the job instruction is detected by the job instruction detection unit 400a and it is recognized that the reception of the print data is completed. It is temporarily stored in the storage unit 51a. That is, the control unit 30 controls the job management table 511, the job name management table 512,
A print page management table 513 and a print page data section 514 are generated, and each data is stored.
The print data stored in the print page data section 514 is
After that, it is transferred to the printing unit 70.

Here, when the operator notices an error in the print data created by the application and wants to cancel the printing, the print cancel operation key 61a of the printer 210 is pressed. When the print stop operation key 61a is operated, the print stop program 420 in the ROM 41 is started, and the following print stop processing is executed.

FIG. 11 is a flowchart of the stored data erasing process. When the print stop operation key 61a is operated (step S41), the print data of the page whose printing has already been started is transferred from the print data storage unit 51a to the printing unit 70, and the printing of the page is performed by the printing unit 70. (Step S42). Even if printing is stopped, this portion is printed as it is. On the other hand, the transfer of the remaining print data stored in the print data storage unit 51a is stopped, and the print data waits (step S43). Next, the job list output unit 421 outputs a job list in which the job number of the job management table 511 of the print data storage unit 51a is associated with the job name of the job name management table 512, and the print unit 70 prints out the job list. (Step S44).

When a job number is input by the job number operation section 61b (step S45), the operated job number is searched from the job management table 511 of the print data storage section 51a by the job number search section 425 (step S45). Step S46). Next, it is determined whether the reception of the print data of the searched job number has been completed (step S47). If it is determined that the reception has not been completed, the reception data discarding unit 423 performs the reception data discarding process. It is started (step S48).

Next, the print data corresponding to the job number searched by the job number search unit 425 is deleted from the print data storage unit 51a by the storage data deletion unit 422. That is, the corresponding data in the job management table 511, the job name management table 512, the print page management table 513, and the print page data section 514 are deleted, and the data of the subsequent address is moved up (step S49). Next, information indicating that the printing process of the job number has been stopped is output to the printing unit 70 by the printing stop information output unit 424, and printed out by the printing unit 70 (step S50). Next, the print data storage unit 51
The print waiting state of a is released (step S51).

If it is determined in step S45 that the reception of the print data corresponding to the job number operated by the job number operation unit 61b has not been completed (step S47, YES), the reception data discard unit 42
3 is started (step S4).
8). FIG. 12 is a flowchart of the received data discarding process. In the received data discarding unit 423, when 1-byte print data is received by the receiving unit 20 (Step S61),
The received print data is analyzed by the job instruction detecting unit 400a, and it is determined whether the received print data is a job end instruction (step S62). Here, when it is determined that the print data is not the job end command, the print data is discarded (step S63), the process returns to step S61, and the next 1-byte print data is received by the receiving unit 20. On the other hand, if it is determined that the print data is a job end command, the received data discarding process ends.

<Effects> As described above, according to the specific example 2, the computer 110 includes the job instruction adding unit 10a
Thus, a job start command is added to the head of the print data and a job end command is added to the end of the print data for each print job, and a file name is added to the header of the print data by the file name adding unit 11b. The printer 210 stores the print job file name and its print data in the print data storage unit 51a in association with the job number. And
When the print stop operation key 61a is operated, the job list output unit 421 outputs a job list in which job numbers and file names are associated with each other to the printing unit 70, and the printing unit 70 prints out the job list. When the job number is input by the job number operation unit 61b, the print data corresponding to the job number input by the operation is deleted from the print data storage unit 51a by the storage data deletion unit 422.

For this reason, the file name of the print job stored in the print data storage unit 51a is notified to the operator by the job list, and the job number corresponding to the file name to be deleted is input by the job number operation unit 61b. Therefore, print data to be erased can be easily selected, and the corresponding print data can be surely erased.

When the job number input by the job number operation unit 61b is searched from the print data storage unit 51a by the job number search unit 425, the reception of the print data of this job number is not completed. The print data is discarded by the received data discarding unit 423 until the job command detecting unit 400a detects the job end command. Therefore, the print data can be received and discarded at high speed. Further, the job instruction detecting unit 40
When a job end command is detected by 0a, the received data discarding process of the received data discarding unit 423 is terminated.
There is no need to discard other print data received subsequently by the receiving unit 20. Therefore, it is possible to stop printing and eliminate waste of printing without hindering other print data.

In the specific example 2, the file name adding unit 1
1b, a file name is added as identification information for identifying print data of a print job. However, the identification information is not limited to a file name,
When a job list is printed out by the job list output unit 421 of the 20 devices, any print job can be identified as long as the print job can be identified from other print jobs.

6).

Next, the stored data erasing section 462
The print data corresponding to the found ID number 1 is deleted from the print data storage unit 52a (step S107), and information indicating that the printing process of the ID number has been stopped is output to the printing unit 70 by the print stop information output unit 463. It is output and printed out by the printing unit 70 (step S108). Next, the print waiting state of the print data storage unit 52a is released (step S109).

On the other hand, if the ID number search unit 465 does not search the print data storage unit 52a for an ID number in step S104, the received data discard unit 461 starts the received data discarding process (step S11).
0). Next, the print stop information output unit 463 outputs information indicating that the print data of the ID number is to be discarded by the received data discard unit 461 and the print processing is stopped.
Is output by the printing unit 70 (step S111). Then, the process proceeds to step S109.

FIG. 21 is a flowchart of the received data discarding process. First, it is determined whether the ID number search unit 465 has searched for the ID number 1 from the print data storage unit 52a (step S121). Step S121
In a case where the ID number is not searched by the ID number search unit 465, if the 1-byte print data is received by the receiving unit 20 (step S122), the received print data is operated by the ID number operation unit 63a. ID number 1
It is determined whether or not (step S123). Here, if the received print data is not the operated ID number 1, the normally received print data is stored in the print data storage unit 52a, and the process returns to step S122, where the next 1-byte print data is stored. Received.

On the other hand, if the received print data is the operated ID number 1, the process proceeds to step S124, and if one-byte print data is received, the ID number detection unit 45
Based on 0a, it is determined whether the received print data is an ID number (step S125). If the received print data is not an ID number, it is determined that the print data of the print job has not been received, and the print data is discarded (step S126), and step S1 is performed.
Returning to 24, the next 1-byte print data is received.
On the other hand, if the received print data is the ID number, it is determined that print data of another print job has been started, and the received data discarding process ends. On the other hand, step S121
Then, the ID number search unit 465 causes the print data storage unit 52
If the ID number has been searched from a, step S12
Proceeding to No. 4, print data that has not been received is discarded.

If the ID number is not registered in the ID number registration unit 13a of the computer 131,
An ID number 0 is added to the head of the print data by the ID number adding unit 13b. Since the ID number 0 is not assigned to the ID number operation unit 63a of the printer device 230, the printing of the print job cannot be stopped in the printer device 230.

<Effects> As described above, according to the fourth embodiment, the ID number operated by the ID number operation unit 63a of the printer device 230 is registered in the ID number registration unit 13a of the computer 131. In the computer 131, the ID number registered in the ID number registration unit 13a is
It is added to the head of the print data by the D number adding unit 13b. The printer device 230 stores print data for each print job in association with an ID number.

Then, the ID number operation unit 63 a
When a number is input by operation, the print cancel unit program 46
Start 0. In the print canceling unit 460a, the ID number operated by the ID number operating unit 63a is stored in the ID number searching unit 4a.
65, and the storage data deleting unit 462 deletes the print data corresponding to the searched ID number. If the reception of the print data corresponding to the searched ID number has not been completed, the reception unit continues until the ID number added to the print data of another print job is detected by the ID number detection unit 450a. After step 20, the received print data is discarded.

Therefore, the IDs stored in the print data storage unit 52a are not affected by other print data.
The printing of the print data corresponding to the number is stopped, and waste of printing can be eliminated.

If the ID number operated by the ID number operation unit 63a is not retrieved from the print data storage unit 52a by the ID number retrieval unit 465, the ID number detection unit 464 receives the ID number from the reception unit 20. I
The D number is detected, and the print data of the detected ID number is discarded by the received data discarding unit 461.

Therefore, for example, even when the print data is temporarily stored in the printer buffer and not received by the printer device 220, the print data can be discarded and the print processing can be stopped. The ID number operation unit 6
By operating the operation key corresponding to the ID number with 3a, printing can be stopped by a simple operation. Further, since there is no need to be aware of the existence of the printer buffer, the print server, and the like, the operation does not become complicated.

In the specific example 4, the computer 131
1 ID by artificial agreement for each of ~ 136
Although the numbers are registered, the ID number registered in each computer is not limited to one. I operated by the ID number operation unit 63a of the printer device 230
By increasing the D number, it is possible to register a plurality of ID numbers and select a different ID number for each print job. In this case, it is possible to reduce the possibility that print data of a plurality of print jobs having the same ID number is stored in the print data storage unit 52a, and to prevent errors such as stopping printing of necessary print data. .

The received data discarding section 461 of the print canceling section 460a discards the print data received by the receiving section 20 until the ID number of another print data is detected by the ID number detecting section 450a. Make up. The ID number of the other print data is delimiter information for terminating the discarding of the print data. For example, the delimiter information may be an ID number different from the ID number operated by the ID number operation unit 63a. In this case, when a plurality of print jobs transmitted from one computer are consecutive, one operation of the ID number operation unit 63a causes another ID job to be performed.
Until the D number is detected, printing of a plurality of print jobs can be stopped.
