Description

  The present invention relates to a technology for controlling a tear-off operation in which the continuous paper is advanced to a cutting position for cutting the continuous paper after printing on the continuous paper.

Conventionally, a printer that prints on continuous paper performs a tear-off operation that automatically advances to a cutting position for cutting the continuous paper after printing on the continuous paper so that the continuous paper can be cut at the cutting position (for example, Thereafter, a series of sheet conveyance control is performed such that the continuous sheet is retracted to the printing position for the next printing.
By the way, continuous paper used in a printer is roughly classified into roll paper and folding paper (fan hold paper). The roll paper is a roll of a strip-like paper having a predetermined width and a long length, and the folded paper is a belt-like paper having a predetermined width and a long length. The perforation line for cutting is put in and folded. When folding paper is used for continuous paper, it is usually cut out in units of printed matter.
Therefore, in a printer that prints on folded paper, when printing over multiple pages, page feed is performed after printing is completed, and the tear line for cutting to separate the print page from the next page is positioned to the cutting position during tear-off operation. Thus, the folding paper is advanced so that it can be cut in units of printed matter. After the tear-off operation, the folding paper is moved backward so that the printing position is at the top position of the next page.

In order to process the print job command generated by the printer driver for the printer without any problem, it is configured to emulate another manufacturer's printer or another printer having a different model number, and this configuration will be described with reference to FIG. To do.

FIG. 2 is a block diagram illustrating a functional configuration of the control unit 2 of the printer 1. Each function shown in this figure is realized by a program 100 stored in the flash ROM 5. As shown in this figure, the control unit 2 includes an emulation determination unit 101, a command emulation unit 102, a print engine 103, and a tear-off operation determination unit 104.
The emulation determination unit 101 determines whether the print job command Pcm received from the computer terminal 30 matches the command for the printer 1 and whether the print job command Pcm is for another manufacturer or a printer with a different model number. If the print job command Pcm is for the printer 1, the print job command Pcm is output to the print engine 103. If the print job command Pcm is not for the printer 1, the print job command Pcm is output to the command emulator. Output to the rate unit 102.

  The command emulation unit 102 converts the print job command Pcm into a command for the printer 1 and outputs it to the print engine 103. Specifically, the command emulation unit 102 includes conversion data 110 for cross-referencing each command used for a print job command by a printer driver for another printer having a different manufacturer or different model number with a command for the printer 1. A code conversion unit 111 that converts the print job command Pcm based on the conversion data 110 is provided.

The print engine 103 executes printing on continuous paper as recording paper and transport of continuous paper during printing based on the print job command Pcm, and includes a print control unit 112 and a paper transport control unit 113. ing.
The print control unit 112 outputs a control signal to the recording head control circuit 18 to control printing by the recording head 13 and sends a control signal to the motor control circuit 19 in order to move the recording head 13 in the width direction of the continuous paper.

A tear-off control unit 114 is provided for controlling the tear-off operation after printing is completed.

  The tear-off operation determination unit 104 specifies an operation mode of the tear-off control unit 114. More specifically, the printer 1 according to the present embodiment performs a page feed after the end of printing as an operation mode of the tear-off operation after the end of printing, and then advances the continuous paper to the cutting position of the continuous paper cutting unit 20. The first operation mode in which the continuous paper is moved backward so that the print start position is aligned with the start position of the next page, and after the line feed is executed after printing is finished, the continuous paper is advanced to the cutting position of the continuous paper cutting unit 20 The second operation mode has a second operation mode in which the continuous paper is moved backward so that the print start position is aligned with the start position of the line feed, and either of the two operation modes should be executed by the tear-off control unit 114. The tear-off operation determination unit 104 determines the operation mode.

  Specifically, the tear-off operation determination unit 104 has a dip switch 115 for setting the operation mode, and the operation mode of the tear-off control unit 114 is determined based on the setting state of the dip switch 115. Note that the operation mode of the tear-off control unit 114 is not limited to the configuration using the dip switch 115 but may be configured to use, for example, an operator disposed in the operation unit 8. Further, the operation mode may be stored in the flash ROM 5 and read out.

Next, the operation of the printer 1 of this embodiment will be described.
FIG. 3 is a flowchart of the printing process of the printer 1. As shown in this figure, when receiving the print job command Pcm, the control unit 2 initializes the counter N to “0” and the counter M to “3000” (step Sa1). These counters N and M will be described. The counter N counts the elapsed time from when the reception of the print job command Pcm is completed until the next print job command Pcm is received in order to execute time-out printing. The counter M determines the timeout time. That is, the counter N increments the count value by “ 1” after the count value is initialized, and when the counter value reaches “3000” that is the value of the counter M, that is, “3 seconds ” that is the timeout time. Is reset to "0".

  Next, the control unit 2 determines whether or not there is a print job command Pcm to be printed in the input buffer of the RAM 4 (step Sa2). When the print job command Pcm is present in the input buffer (step Sa2: YES), the control unit 2 analyzes the command (step Sa3), and controls the printing mechanism 12 based on the command analysis result to print ( After executing printing and paper conveyance (paper feeding) (step Sa4), the processing procedure is returned to step Sa1 in order to wait for the next print job command Pcm.

On the other hand, if the result of the determination in step Sa2 is that there is no print job command Pcm in the input buffer (step Sa2: NO), that is, printing based on the print job command Pcm is completed and the next print job command Pcm is waiting. If there is, the control unit 2 increments the counter N by “1” when “1 msec ” has elapsed (step Sa5), and determines whether or not the counter value of the counter N has become larger than the value of the counter M. (Step Sa6).

When the counter value of the counter N is less than or equal to the value of the counter M (step Sa6: NO), the control unit 2 returns the processing procedure to step Sa1 to indicate that the timeout time has not elapsed, and next print job. Wait for command Pcm.
On the other hand, when the counter value of the counter N is larger than the value of the counter M (step Sa6: NO), the control unit 2 executes the following process to perform time-out printing in order to indicate that the time-out time has elapsed. That is, the control unit 2 determines whether a request for printing (printing) / paper conveyance (paper feeding) based on the print job command Pcm remains in the printer 1 (for example, a buffer in the RAM 4) (step Sa7). If it remains (step Sa7: YES), after executing printing (printing) and paper conveyance (paper feeding) based on the request (step Sa8), a tear-off operation is executed (step Sa9). Thereafter, the processing procedure is returned to step Sa1, and the next print job command Pcm is awaited.

The tear-off operation in step Sa9 will be described with reference to FIG.
FIG. 4 is a flowchart of the tear-off control process.
As shown in this figure, when performing the tear-off operation, the control unit 2 performs page feed (FF) based on whether the first operation mode or the second operation mode is designated by the tear-off operation determination unit 104. It is determined whether or not to execute Tear Off without performing (Step Sb1). As a result of this determination, when page feed is executed (step Sb1: NO), that is, when the first operation mode is designated, the control unit 2 performs TOF (heading) prior to executing page feed. It is determined whether or not the (positioning position) is a “0” mm position, that is, whether or not the current printing position is already positioned at the top of the next page (step Sb2).

As a result of this determination, if the TOF (cue position) is the “0” mm position (step Sb2: YES), the control unit 2 does not need to perform a page feed and thus performs a tear-off as it is (step Sb2: YES). Sb3). Further, when the TOF (cue position) is not the “0” mm position (step Sb2: NO), that is, when the printing is finished in the middle of the page, the control unit 2 performs the page feed. The paper feed amount is calculated (step Sb4). This paper feed amount O is calculated by subtracting the distance E from the top of the page (“0” mm position) to the current print position from the page length L.
Next, the control unit 2 conveys the continuous paper by the paper feed amount O and executes page feed (step Sb5), advances the processing procedure to step Sb3, executes tear-off (Tear Off), and ends the processing. Thus, the continuous paper is conveyed so that the vicinity of the boundary between the print page and the next page is located at the cutting position of the continuous paper cutting unit 20, and the continuous paper can be cut at the boundary.

  On the other hand, as a result of the determination in step Sb1, if page feed is not performed (step Sb1: YES), that is, if the second operation mode is designated, the control unit 2 changes the print position after a line feed (step Sb6). ), The process procedure proceeds to step Sb3 to execute Tear Off, and the process ends. Thereby, the continuous paper is conveyed so that the vicinity of the boundary between the last line and the next line of printing is located at the cutting position of the continuous paper cutting unit 20, and the continuous paper can be cut at the boundary.

  Through the above processing, tear-off is executed in the designated operation mode. Therefore, for example, even when printing on continuous paper with a perforation line for cutting, by selecting the second operation mode in which printing starts from the next line after tear-off, it is It is possible to start printing from the next line without generating extra blank lines, and by selecting the first operation mode in which printing starts from the next page after tear-off, Printing (printing) is possible. Needless to say, roll paper without the perforation line for cutting may be used as continuous paper.

  Further, after the tear-off operation is performed, the continuous paper remains in the fed state, and when the next printing is started, that is, when the next print job command Pcm is received, the continuous paper is returned to the printing position. Will be fed. At this time, in the first operation mode, the continuous paper is back-fed to the top position (“0” mm position) of the page and the next printing is started. In the second operation mode, the continuous paper is supplied up to the line feed position. Is moved backward (back feed) and the next printing is started.

As described above, according to the present embodiment, the following operations and effects are achieved.
That is, in the present embodiment, the first operation mode in which the tear-off operation is performed after page feed is performed and the print start position after the tear-off is to be the next line so that the print start position after the tear-off is the top of the next page. Any one of the second operation modes in which the tear-off operation is performed after a line feed is designated by the tear-off operation determination unit 104. As a result, the user can select the second operation mode, and even when printing on continuous paper with a perforation line for cutting, an extra blank line is not generated between the previous printing and the printing. Printing can be started from the next line.

  According to the present embodiment, in the first operation mode, after page feed is performed when printing on continuous paper is finished, the continuous paper is fed to a cutting position for cutting by a tear-off operation. Therefore, when continuous paper with a perforation line for cutting is used as continuous paper, the continuous paper is fed to the position with the perforation line for cutting after printing, and then the cutting position of the continuous paper cutting unit 20 Since the continuous paper is conveyed so as to be positioned at the position, the continuous paper can be easily cut.

Further, according to the present embodiment, when the print job command Pcm is emulated, the tear-off operation is executed according to the first or second operation mode after the printing based on the emulation is completed. Regardless of the specifications of the printer to be emulated, the operation mode can be reliably controlled.
Further, according to the present embodiment, since the operation mode can be selected and set by the operator such as the DIP switch 115, the selection and setting of the operation mode can be easily performed manually.

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 operation mode can be selected and set by the operator such as the DIP switch 115. However, the present invention is not limited to this, and a command for specifying the operation mode by the printer driver 31 of the computer terminal 30 is set to the print job command Pcm. The control unit 2 of the printer 1 may determine the operation mode based on the command. According to this configuration, when the print job command Pcm is transmitted from the computer terminal 30 to the printer 1, the operation mode can be easily designated in accordance with printing.
The designated operation mode may be stored in the flash ROM 5 and read out in accordance with a command for designating the operation mode.

  Further, for example, in the above-described embodiment, the printer 1 includes the command emulation unit 102 and can process print job commands Pcm for printers of different manufacturers or different models. If the print job command Pcm for a different printer is not received, the command emulator 102 need not be provided.

Further, for example, in the above-described embodiment, the printer 1 that prints on continuous paper is illustrated, but a configuration that can print on both continuous paper and cut paper may be used. In this configuration, when printing on continuous paper, a tear-off operation corresponding to the designation of the operation mode is executed.
Further, for example, in the above-described embodiment, the configuration is such that the tear-off operation is executed after the time-out printing. The operation may not be executed.
In addition, a time-out time until the time-out printing is started, that is, the value of the counter M may be configured so that the user can appropriately set it by operating the operation unit 8 or the print job command Pcm.
The recording head 13 is not limited to a serial impact dot matrix (SIDM) printer head, but may be an inkjet head, a laser head, a thermal head, or the like.
