Abstract

PROBLEM TO BE SOLVED: To shorten a time to a final printing end by properly handling a printing request inputted during a printing issuance process. SOLUTION: In printing to continuous forms papers, if a next printing request is not present (N in S39) before a predetermined time passes (N in S41) after a printing request is inputted and a printing operation based on the printing request finishes, a printed part is sent to a cutting position by a cutter of the printer and cut, and a not printed part is fed back to a printing position. When the next printing request is present (Y in S39) before the predetermined time passes, a printing operation based on the printing request is started, and the printed part is cut when the printed part reaches the cutting position along with the printing operation. Even when the next printing quest is inputted during the printing based on the printing request or immediately after the printing, if it is before the predetermined time passes, the printing based on the next printing request is taken into a process of the previous printing request and carried out.

The cutter 3 is disposed downstream of the thermal head 1 and the platen roller 2 in the paper transport path 4 and cuts a printed portion of the continuous paper S. An ink ribbon R is hung on the thermal head 1.

In such a printer, the continuous paper S is transported in the paper transport path 4 by rotating the platen roller 2 while being sandwiched between the thermal head 1 and the platen roller 2, and while being transported. Printing is performed by the thermal head 1. Then, the printed portion is cut by the cutter 3.

FIG. 8 is a flowchart showing a flow of a conventional paper cutting control method of a printer. First, when there is an instruction for an issuance process, the process is distributed (S1). Here, at the end of the pre-processing, the next processing is designated. If the designated process is the slow-up process, the slow-up process is started (S2), and when the slow-up is completed (Y in S3), it is designated to proceed to the constant speed printing process (S4). It returns to step S1.

Next, since it is specified that the constant speed printing process is to be performed, the process moves from step S1 to step S5 to start the constant speed printing process. Then, during printing, it is determined whether or not the printed portion has reached the cut timing (S
6) If the cut timing has come (Y in S6), a cut operation is performed (S7), and the process proceeds to step S8. If the cut timing has not been reached (S6
N), the process directly proceeds to step S8.

In step S8, it is determined whether or not the printing started in step S5 has been completed. If the printing has not been completed (N in S8), the process returns to step S1, and if it has been completed (Y in S8), the process proceeds to step S9. Move on.

In step S9, it is determined whether or not printing for the print request has been completed. If the printing has not been completed (N in S9), the process returns to step S1, and if it has been completed (Y in S9).

Next, since it is specified to perform the slowdown process, the process proceeds from step S1 to step S13, where the slowdown process is started (S13). When the slowdown is completed (Y in S14), the next process is performed. It is designated to proceed to the slow-up process (S15), and the process returns to step S1.

FIG. 9 is a timing chart of printing and cutting, and FIG. 10 is a schematic diagram showing the position of the continuous paper S at each time. For example, when there is a print request specifying that the number of prints is two, first the first print is performed (A in FIG. 9, (a) to (b) in FIG. 10), and after a predetermined standby time, (A to B in FIG. 9) The second sheet is printed (B to C in FIG. 9,
(B) to (d) of FIG. Here, during printing of the second sheet, 1
Since the printed portion of the first sheet is sent, when the printed portion reaches the cut position, the printed portion of the first sheet is cut (FIG. 10C).

When the printing of the second sheet is completed (C in FIG. 9), the sheet is fed to the cut position of the second sheet (C to D in FIG. 9, and (d) to (e) in FIG. 10). (D in FIG. 9 and (e) in FIG. 10), and the unprinted portion of the continuous paper S is fed back to the printing position (E to F in FIG. 9 and (e) to (e) in FIG. 10).
(f)).

Here, it is assumed that there is a print request for the third sheet at the timing of C in FIG. Even in this case, the third sheet is printed with a predetermined standby time interposed therebetween (FG in FIG. 9) (FIG. 9).
G to H, FIG. 10 (f) to (g)), the printed portion is fed to the cut position (HI to I in FIG. 9, and (g) to (h) in FIG. 10) and cut (FIG. 9). I, FIG. 10 (h)). Then, the unprinted portion of the continuous paper S is back-fed to the printing position (J to K in FIG. 9, and (h) to (i) in FIG. 10).

[0012]

In the above-described conventional paper cut control method for a printer, even if a next print request is input during printing for a certain print request, printing for the previous print request is issued. Unless (S1 to S15 in FIG. 8) is completed, printing for the next print request is not performed.

However, if the next print request is during printing or immediately after the end of printing for the previous print request, the last sheet for the previous print request is sent to the cutting position and cut to remove the unprinted portion. It is faster to start printing for the next print request and cut the last sheet for the previous print request during printing than to back feed to the print position Probability is high.

SUMMARY OF THE INVENTION It is an object of the present invention to appropriately handle a print request entered during a print issuance process to shorten the time until the final printing is completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a paper cutting control method for a printer according to the present invention will be described with reference to FIGS.

FIG. 1 is a schematic diagram showing a schematic structure of a printer. The printer has a thermal head 11, a platen roller 12, and a cutter 13. The thermal head 11 and the platen roller 12 are disposed so as to sandwich a paper transport path 14, which is a path through which the continuous paper S is transported. The thermal head 11 has one end rotatably supported and the other end rotatably supported. It is urged by an urging member (not shown) so as to come into pressure contact with the platen roller 12. The cutter 13 is disposed downstream of the thermal head 11 and the platen roller 12 in the paper transport path 14 and cuts a printed portion of the continuous paper S. An ink ribbon R is hung on the thermal head 11. The ink ribbon R is supported in a state where both ends are wound by two ribbon cores 15 and 16. The unused side of the ink ribbon R is wound around the ribbon core 15, and the used side of the ink ribbon R is wound around the ribbon core 16.

In such a printer, the continuous paper S is transported through the paper transport path 14 by rotating the platen roller 12 while being sandwiched between the thermal head 11 and the platen roller 12, and while being transported. Printing is performed by the thermal head 11. The thermal head 11 has a large number of heating elements arranged in the width direction of the continuous paper S,
By causing an appropriate one of these heating elements to generate heat, the ink applied to the ink ribbon R is melted,
The melted ink is transferred to the continuous paper S and printed on the continuous paper S. And the printed part is cutter 1.
Cut at 3.

FIG. 2 is a block diagram showing the electrical connection of each section provided in the printer. The printer has a CPU 17 that executes various arithmetic processes and centrally controls each unit.
A ROM 18 and a RAM 19 are connected to the CPU 17 via a system bus 20. ROM18
Is a medium storing the operation program of the printer,
The CPU 17 controls each unit according to the operation program. The RAM 19 temporarily stores various types of variable information. Further, a partial area of the RAM 19 is used as various counter areas or as a drawing memory 21. In the drawing memory 21, data of an image to be printed on the continuous paper S is drawn based on a program and various data stored in the ROM 18.

The CPU 17 also has an I / F 22 and an EE
PROM 23, thermal head 11, various sensors 2
4 and a driver 26 that rotationally drives the pulse motor 25
And a ribbon core 15 for transporting the ink ribbon R.
A driver 28 that controls a ribbon DC motor 27 that drives the rotation of the cutter 16 and a driver 30 that controls a cutter motor 29 that drives the cutter 13 are connected.

The I / F 22 is connected to an external device (not shown) such as an upper host for transmitting print data. E
The EPROM 23 is a non-volatile memory that stores data that does not want to be lost even when the power is turned off. The pulse motor 25 is a drive source for driving the platen roller 12 to rotate.

For example, when a command requesting print is received from a higher-level host connected to the I / F 22, this request is transmitted to the CPU 17 via the system bus 20.
The CPU 17 writes the data of the image to be printed into the drawing memory 21 according to the program stored in the ROM 18. Then, the data in the drawing memory 21 is transferred to the thermal head 11 at a predetermined timing. The thermal head 11 causes a predetermined heating element to generate heat based on the transferred data.

Note that a wait timer described later is RA
By using a partial area of M3 as a counter area, clock pulses are started to be counted at a predetermined timing, and a time-up is performed when the count is completed to a count number set to an appropriate value in advance for each timer. Has been realized.

Next, a paper cutting control method of the printer will be described with reference to a flowchart shown in FIG.
First, the process is distributed (S21). Here, at the end of the pre-processing, the next processing is designated. If the specified process is a slow-up process, the pulse motor 2
5 is started to gradually increase the speed by driving (S22), and when the slow-up is completed (S22).
23Y), next, it is designated to shift to the constant speed printing process (S24), and the process returns to step S21.

Next, since it is specified that the constant speed printing process is to be performed, the process moves from step S21 to step S25 to start the constant speed printing process for keeping the driving speed of the pulse motor 25 constant. Then, during printing, it is determined whether or not the cut timing of the printed portion has come (S26).
If the cut timing has come (Y in S26),
The cutter motor 29 is driven to move the cutter 13 to perform a cutting operation (S27), and the process proceeds to step S28. If the cut timing has not been reached (N of S26), the process directly proceeds to step S28.

In step S28, it is determined whether or not the printing started in step S25 has been completed. If the printing has not been completed (N in S28), the process returns to step S21. If the printing has been completed (Y in S28), the process proceeds to step S9. Move on.

In step S29, it is determined whether or not printing for the print request has been completed, and if not completed (S2).
9) N) Return to step S21, and if it is completed (S2
9: Y) The process proceeds to step S30.

In step S30, it is determined whether or not the printed portion is to be cut.
(Y of 30), the process proceeds to step S31, and it is checked whether the weight setting value is 0.

Here, the weight setting value is a time period for temporarily stopping the conveyance of the continuous paper S, which is set as a predetermined period, and is set to an arbitrary value in advance by the operator and set to the EEP.
It is stored in the ROM 23. Here, the function of the setting means is realized. As a result, the weight set value becomes an effective value that differs depending on the data transfer speed, the amount of information, and the size of the data drawing load when print data is sent from an upper host (not shown) connected to the I / F 22, for example. , Can be set arbitrarily.

If the weight setting value is 0 (S3
(1) Y), the cutter motor 29 is driven to move the cutter 13 to perform a series of cutting operations (S32), and the process returns to step S21. Here, in a series of cutting operations, the pulse motor 25 is driven to send the last printed portion to the cutting position, cut, and the pulse motor 25 is reversed to feed back the remaining unprinted portion to the printing position. This is the operation up to. In step S31, if the weight setting value is a numerical value other than 0 (N in S31), a wait timer is started (S33), and it is designated to proceed to a slowdown process (S34), and the process proceeds to step S21. Return.

Next, since it is specified to perform the slowdown process, the process moves from step S21 to step S35, where the slowdown process of the pulse motor 25 is started.
When the slowdown has been completed (Y in S36), it is specified that the process should be shifted to the idle process (S37), and the process proceeds to step S2.
Return to 1.

Next, since it is specified that the idle process is performed, the process moves from step S21 to step S38 to start the idle process (S38). Next, it is checked whether a new print request is included (S3).
9). If a new print request has not been received (N in S39), it is checked whether the wait timer is running (S40). If it is not running (N in S40), the process returns to step S21. It is determined whether the time is up (Y in S40) (S41). here,
After activating the wait timer in S33, the EEPROM
The time is up when the weight set value stored in the storage unit 23 has elapsed.

Up to this point, the function of the print request detecting means is executed.

If the time is not up in S41 (N in S41), the flow returns to S21. If the time is up in S41 (Y in S41), the wait timer is stopped (S42), the same series of cutting operations as in S32 are performed (S43), and the process returns to S21.

If a new print request is received in S39 (Y in S39), the wait timer is stopped (S4).
4) Next, specify to proceed to slow-up processing (S
45), and returns to the step S21.

Thus, the function of the sheet transport control means is realized.

In such a configuration, the case where a third print request is received during a print operation based on a print request designated as two print sheets and all three sheets are cut and issued is described. An example will be described with reference to FIGS. FIG. 4 is a timing chart in that case, and FIG. 5 is a schematic diagram showing the position of the continuous paper S at each time. Here, in this example, it is assumed that a waiting time for two graduations in FIG. 4 is required from when a printing request is received to when printing is started. Further, in this example, the weight setting value is 3 in FIG.
It is assumed that the time is set to the scale time.

First, after receiving a print request for two sheets, a standby time for two scales in FIG.
21 to S24), the first sheet is printed at a predetermined timing (Y in S25 to S28 in FIG. 3, A in FIG. 4, and (a) in FIG. 5).
~ (B)). Then, after a predetermined standby time during which various processes are performed (N to S21 in S29 in FIG. 3, and A to S in FIG. 4).
B) The second sheet is printed (S25 to S28 in FIG. 3)
Y, B to C in FIG. 4, and (b) to (d) in FIG. Where 2
During the printing of the first sheet, the printed portion of the first sheet is sent,
When the printed portion reaches the cut position, the first printed portion is cut (Y to S27 in S26 in FIG. 3, and (c) in FIG. 5).

After the printing of the second sheet is completed (Y in S29 of FIG. 3,
4 (C) and FIG. 5 (d)), since the second printed portion is the cut target (Y in S30 in FIG. 3) and the weight setting value is not 0 (S31 in FIG. 3). N), a wait timer is started (S33 in FIG. 3). Then, slow down processing is performed (Y in S34 to S36 in FIG. 3), and idle processing is started (S37 to S38 in FIG. 3).

Here, in this example, as shown in FIG.
At the end of printing the third sheet, a print request for the third sheet is input. Then
Since it is checked in S39 in FIG. 3 that a new print request has been received (Y in S39 in FIG. 3), the wait timer is stopped (S44 in FIG. 3), and slow-up processing is performed (S45 to S45 in FIG. 3). Y in S23). The process up to this point is performed for the time corresponding to two scales in FIG. 4 (C to D in FIG. 4). Then, the third printing is performed (Y in S25 to S28 in FIG. 3, D to E in FIG. 4, and (d) to (f) in FIG. 5). 3 and 3
During the printing of the first sheet, the printed portion of the second sheet is sent to reach the cut position. At that point, the printed portion of the second sheet is cut (Y to S27 in S26 in FIG. 3, and FIG. 5). (e)).

After the printing of the third sheet is completed (Y in S29 of FIG. 3,
(E in FIG. 4 and (f) in FIG. 5), since the third printed portion is a cut target (Y in S30 in FIG. 3) and the weight setting value is not 0 (S31 in FIG. 3). N), a wait timer is started (S33 in FIG. 3), slowdown processing is performed (Y in S34 to S36 in FIG. 3), and idle processing is started (S37 to S38 in FIG. 3).

Thereafter, in this example, since a print request is not received, the apparatus enters an idle state until the wait time based on the wait set value elapses (N in S39 in FIG. 3; N in S41 in FIG. 3, EF in FIG. 4). When the time elapses (Fig. 3
(Y in S41, F in FIG. 4), the wait timer is stopped (S42 in FIG. 3), and a series of cutting operations are performed (S43 in FIG. 3, F to I in FIG. 4, and (f) to (f) in FIG. 5). (h)) The third sheet is cut (G in FIG. 4 and (g) in FIG. 5).

Next, as a second example, a case where a print request is received immediately before the elapse of the wait time based on the wait set value after the printing of the second sheet is completed, the second example will be described with reference to the timing chart of FIG. explain. Other settings are the same as in the first example. In addition, detailed description of the same parts as in the first example is omitted.

In this example, after the printing of the second sheet is completed (C in FIG. 6), the printer temporarily enters an idle state (C to D in FIG. 6), and a print request for the third sheet is received immediately before the elapse of the wait time (FIG. 6). 6D), the third sheet is printed (E to F in FIG. 6) after a predetermined standby time (D to E in FIG. 6). Then, during the printing of the third sheet, the printed portion of the second sheet is sent to reach the cut position. At that time, the printed portion of the second sheet is cut. After that, it is the same as the first example.

In the present embodiment, the weight setting value is set so that the time until the cutting of the third printed portion is equal to or less than the time required when the weight setting value = 0. The operator sets the weight setting value appropriately.

According to this embodiment, when the next print request is made during printing or immediately after printing for the previous print request, it is possible to promptly issue the printing for this print request. it can.

[0058]

According to the first aspect of the present invention, even if a next print request is received during or immediately after printing based on a print request, if a predetermined period has not elapsed, the previous print request is printed. Since the print process is performed based on the next print request after being taken into the processing process, for example, if the next print request is received immediately after the completion of the print based on the print request, the print related to this print request is put on the shelf and printed. It is possible to eliminate the waste of time caused by giving priority to the cutting of the portion, thereby shortening the time until the final printing is completed.

According to the second aspect of the present invention, the predetermined period can be appropriately set in the first aspect of the present invention.
For example, as in the case where print data is sent from an upper host, it can be arbitrarily set to a different effective value depending on the speed of data transfer, the amount of information, and the magnitude of data drawing load.

According to the third aspect of the present invention, in the first or second aspect of the present invention, even when a label sheet is continuously issued, a next print request is received during or immediately after printing based on a print request. Before the elapse of the predetermined period, the printing process based on the next printing request is also performed following the printing process of the previous printing request. In this case, it is possible to eliminate the waste of time caused by shelving the printing related to the printing request and giving priority to issuing the printed label paper, thereby reducing the time until the final printing is completed. Can be shortened.

According to the fourth aspect of the present invention, after printing based on a print request is completed, the printer is idle for a maximum of a predetermined period. If the next print request is received during or immediately after printing based on the print request, the print request is accepted when the printer is in the idle state. Since it is taken into the processing process and performed, for example, when the next print request is received immediately after the end of printing based on the print request, the print related to this print request is shelved and the printed part of the previous print request is cut. Waste of time caused by giving priority to the printing can be eliminated, whereby the time until the final printing is completed can be shortened.

According to the fifth aspect of the present invention, the predetermined period can be appropriately set in the fourth aspect of the invention.
For example, as in the case where print data is sent from an upper host, it can be arbitrarily set to a different effective value depending on the speed of data transfer, the amount of information, and the magnitude of data drawing load.

According to the sixth aspect of the present invention, in the invention of the fourth or fifth aspect, even in the continuous issuance of label paper, when a next print request is received during printing based on a print request or immediately after printing. Since the print request is accepted when the printer is in the idle state, and the print processing based on this print request is also taken in the print processing step of the previous print request, for example, immediately after the end of the print based on the print request, When the next print request is received, it is possible to eliminate the waste of time caused by shelving the print related to this print request and giving priority to the issuance of the printed label paper. It is possible to shorten the time until the end of a typical printing.
