[Action]

In order to perform print control according to the present invention, as shown in FIG. 1, after the printing paper is loaded in the printer device in response to receiving the loading instruction from the host device in step S1, a print command is issued from the host device. To have.

If a print command is received in step S2,
In S3, of the print data to be printed on the printing paper, the print data of a predetermined line or column, for example, one line of print data is written in the print buffer provided in the printer.

At that time, in step S4, the presence / absence of the paper provided in the printer device determines whether or not there is the print paper for printing for the rows or columns.

If the printing paper exists in the print size of the row or column, printing is performed in step S5, but if the printing paper does not exist in the row or column, the printing paper is stored in the print buffer in step S41. Delete the print data for the relevant row or column.

On the other hand, in the case of the second invention, when the print command is received in step S2 as shown in FIG. 2, unlike the above-described first invention, before the print data for the rows or columns is written in the print buffer. Then, in step S4, the presence or absence of printing paper is determined.

If printing paper exists, the process proceeds to step S3 to write the print data to the print buffer, but if no paper exists, the process proceeds to step S42 to erase the received print command. No print data is written to the print buffer. Here, of the paper length recognized by the host device, for the print data that cannot be printed on the print paper, the print data stored in the print buffer is deleted or the print command is deleted to print. The reason for stopping is to prevent printing on a place other than the printing paper, for example, a place such as a platen, and also to prevent printing on the printing paper other than the printing paper on which the print data should be printed.

Thus, after printing (S5) or erasing (S41) in the first invention or after printing (S5) or erasing the print command (S42) in the second invention, the process proceeds to step S51, Check if there is a paper length instruction from the host device,
It is determined whether or not the processing for the paper length recognized by the host device has been completed. Then, if there is a paper length instruction from the host device, since the processing for the paper length has been completed, the process returns to step S1 to receive the instruction to attach the printing paper,
When the print paper is to be loaded in the printer device and there is no paper length instruction, it means that the processing for the paper length recognized by the host device has not been completed yet.
After the paper feed is performed in step S2, the print command is received again in step S2.

〔Example〕

Next, examples of the first and second inventions will be described.

FIG. 3 shows a block diagram of a device configuration of the printer device according to the present embodiment.

The printer device 2 is connected to a host computer 1 as a host device that sends print data for requesting printing to the printer device and a print command for the print data.

The printer device 2 includes a receiving unit 4 for receiving print data sent from the host computer 1, a receiving buffer 5 for storing print data sent from the host computer 1, and a printer unit 2 for receiving the print data. Paper presence / absence detection sensor 6 using an optical sensor or the like for detecting whether the attached single-cut printing paper is present at a predetermined position
And a printing unit 7 such as a print head for printing on the printing paper.
A print buffer (line buffer) 8 for storing one line of print data to be printed at a time among the print data stored in the reception buffer 5, and the print data stored in the print buffer 8. Of the print buffer erasing unit 9 configured by computer software for erasing data, a line feed unit 10 for feeding one line of paper when printing is completed, and the printing unit 7 along the main scanning direction, that is, along the line. It has a space 11 for moving the print head, and a main controller 3 composed of a CPU for performing various controls on the printer device 2.

Next, the operation of this embodiment (related to the first invention) will be described with reference to FIG.

In this embodiment, when there is an instruction by a command from the higher-level device to load a single-cut printing paper in the printer device 2 in step SA1, the printer device 2 receives the instruction in step SA2, and manually or in step SA3. The printing paper is automatically attached to the printer device.

The host computer 1 as a host device steps
The print data to be printed by SA4 is sent in specified amounts. Upon receiving the print data in step SA5, the receiver 4 of the printer device 2 temporarily stores the print data in the reception buffer in step SA6.

Thereafter, the host computer transmits the print command for one line in step SA7.

The print command is temporarily stored in the reception buffer 5 in step SA8. The instruction is read by the main control unit 3 of the printer device 2 and one line of the print data once stored in the reception buffer is read out, and the step SA9
Then, the data is written in the print buffer 8.

Then, in step SA10, the presence / absence of the printing paper is determined by the paper presence / absence detection sensor 6. If it is determined that there is print paper, the print data stored in the print buffer 8 is printed as in the conventional case, and if it is determined that there is no print paper, the process proceeds to step SA12 and the print buffer 8 is stored. The stored print data will be erased.

On the other hand, the host computer 1, which is the host device, confirms in advance how many times the print command for each line should be issued based on the paper length of the printing paper loaded in the printer device, and is determined in advance in step SA13. Each time a print command is sent, it is determined whether or not the print command has been sent a certain number of times, and the print command is repeated until this number is reached. When the predetermined number of times is reached, a paper length signal indicating that the processing for the paper length has been completed is transmitted in step SA14, and a print command is transmitted for a predetermined time in step SA15 in consideration of mounting of the next printing paper. Will be stopped.

If it is determined in step SA16 that the main control unit 3 of the printer device 2 does not receive the paper length signal,
After feeding one line of paper at SA17, the process returns to step SA8 to wait for the print command again, and when the print command is received, the above-described processing is performed.

On the other hand, if it is determined in step SA16 that the paper length signal has been received, and if all printing has not been completed (SA18), the process proceeds to step SA2 again, and an instruction to mount the printing paper is received from the host device. It will be.

Next, another embodiment (related to the second invention) shown in FIG. 4 will be described.

This embodiment differs from the above-mentioned embodiments in that the print buffer 8
In place of the print buffer erasing unit 9 for erasing the print data stored in, the print command erasing unit 19 constituted by computer software for erasing the print command stored in the reception buffer 5 is provided. .

In this embodiment, after the print command is received in step SA8 in the flow chart of FIG. 5, it is judged in step SA10 whether or not the print paper is present. If it is judged that the print paper is present, the same as in the above-described embodiment, the step SA9 is executed. Print buffer 5
The print data for one line is written in and the print is performed in step SA11. However, if it is determined that there is no print paper, the print command stored in the reception buffer 5 is erased and the print data is printed. Is not written in the print buffer 8. Thus, after printing or erasing in step SA11, the process proceeds to step SA16 as shown in FIG.

Thus, as shown in FIG. 6 (b), there is a difference between the paper length recognized by the host computer 1 as the host device and the paper length of the printing paper actually mounted in the printer device. When the actual paper length of the printing paper is shorter than the paper length recognized by the host computer 1, the unprinted portion is erased without being printed, and the newly mounted printing paper is always printed from the beginning. Will be done.

Usually, the deviation between the paper length recognized by the host computer and the paper length of the printing paper actually mounted in the printer is small, and the erased print data is usually small, and the final line Therefore, it is considered that the influence of erasure is small.

Further, in the above-described embodiment, the instruction for mounting the printing paper and the print command are described to be performed by the host device, but the host device is not necessarily limited to the host device and may be instructed by a switch or the like provided in the printer device. Good.

〔The invention's effect〕

As described above, according to the present invention, there is a difference between the paper length recognized by the host device and the printing paper that is actually attached to the printer device, and the paper length recognized by the host device is actually When the size is larger than the size of the printing paper attached to the printer, the print data stored in the print buffer or the print command is erased so that the misaligned printing is not performed.

Therefore, it is possible to prevent a situation in which printing is performed despite the absence of printing paper and cause a failure in the printing unit, and it is possible to prevent inconvenience in which the misalignment is accumulated on subsequent printing paper. It is possible to provide a reliable printer device having a long life.
