DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a page printer.

[0002]

2. Description of the Related Art Conventionally, there is a page printer in which print data transferred from a host machine such as a host computer is developed in a page buffer and then output from the printer unit in the number of print copies. Such a page printer has a page buffer for at least one page. In recent years, in order to enable high-speed printing, when a plurality of print copies are set, the printed sheet is discharged until it is discharged. During this time, the next sheet is sequentially fed.

[0003]

For printing, for example, there are cases where a reduction ratio, an upper margin, and a left margin are designated.
These may change when the print data transferred from the host machine to the page buffer of the page printer is actually output. When the upper margin and the lower margin are designated, the lower end and the right end of the data may exceed the print area.

Therefore, when a plurality of copies are set, if a failure is found by looking at the printing result of the first sheet, it is necessary to press the reset button to stop printing. If you set multiple copies,
Since the next sheet has been fed before the first sheet is discharged, printing cannot be stopped immediately even if the reset button is pressed during printing, and waste of the sheet cannot be avoided.

In order to avoid such waste, first,
After specifying the printing of only one sheet and confirming the printed matter, re-specifying the required number of copies and receiving the same print data from the host machine again, in this case, request the print data from the host machine again. Operation and the data transfer time from the host machine increase. Further, when the reset button is pressed and stopped halfway as described above every time one page of print processing is completed, in the subsequent actual printing, an operation of receiving print data from the higher-level device again must be performed, In some cases, it may be necessary to reset the conditions of the page printer each time. As a result, there is a problem that the operability is poor and the printing efficiency is reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a printing method which has a problem
If found, stop printing immediately and waste paper.
It is to avoid.

[0007] An object of the present invention is to print a test print after printing one sheet.
Resend the upper machine or we print data to discover the defect of the printing data

According to the third aspect of the present invention, the print data transferred from the host machine is stored in the page buffer, and the result of the test print is confirmed while the printer unit is stopped after the test print is executed. Since the main printing can be executed, the operation of receiving print data from the host machine and the operation of setting conditions in the printer unit can be performed only once. Further, when a defect is found as a result of the test printing, the restart of printing can be stopped by the reset unit. Further, when print data of a plurality of pages is transmitted from a higher-level device, the target of test printing can be limited to only the first page determined as a new job. However, the number of test prints can be limited to a minimum. In addition, when a defect is found as a result of the test printing, when the restart of the printing is stopped by the reset unit, the storage of the print data in the page buffer can be prohibited. It is possible to prevent it. In addition, after trial printing,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. First, FIG. 2 shows a configuration of the controller 1 of the page printer. The controller 1 controls data communication with a host computer 2 as a host machine, and also includes a printer unit 3, an operation panel 4, and a disk drive 5.
And the like. The operation panel 4 is for notifying the user of the current operation state of the printer unit 3 and for performing various operations such as setting a mode and setting the number of copies. The disk drive 5 is a floppy disk device or a hard disk device that stores various data such as font data and programs.

A CP for controlling the entire controller 1
U6 includes an NVRAM (non-volatile memory) 7 for storing the contents of mode instructions from the operation panel 4, a program ROM 8 for storing control programs for the controller 1, and a font R for storing font patterns and the like.
OM9, R used for a work memory of the CPU 6, an input buffer for inputting input data, a page buffer for storing print data, a memory for download fonts, and the like.
AM 10, a printer interface 11 for communicating commands, statuses and print data to the printer unit 3, a panel interface 12 for communicating commands and status to the operation panel 4,
A host interface 13 for communicating with the host computer 2 and a disk interface 14 for communicating with the disk drive 5 are connected by a system bus 15. The CPU 6 has an IC card 16 for inputting font data and programs from the outside.
Are connected via the system bus 15.

A plurality of paper feed units (not shown) for supplying various papers to the printer unit 3 are provided. In the two paper feed trays of these specific paper feed units, regular papers and non-regular papers having the same size but separately are stored. Non-regular paper is, for example, paper on which the back surface is printed or recycled paper.

In such a configuration, as shown in FIG. 3, print data is transmitted from the host computer 2 to the input buffer 1 of the RAM 10 via the host interface 13.
0a, and then the data processing unit 17
It is developed as a bitmap in ten page buffers 10b. When a bitmap for one page is created, the print data is sent to the printer unit 3.

Next, the flow of the printing operation will be described with reference to the flowchart shown in FIG. First, the steps (in the figure,
ST. In step 1, a test print mode is set by a predetermined key of the operation panel 4 functioning as test print mode setting means. In step 2, the number of print copies is set by a predetermined key of the operation panel 4 functioning as print copy setting means. Is set, print data is received from the host computer 2 in step 3. This print data is developed in the page buffer 10b in step 4 as described above. Then, in step 5,
It is determined whether or not the test print mode is set. If the test print mode is not set, the process shifts to the main print operation in step 14 by the same processing as in the related art. If it is determined in step 5 that the test print mode has been set, in step 6, the paper feed unit is changed to a paper feed unit for feeding irregular paper, and the paper fed from this paper feed unit is changed. In step 7, one test print is performed. Step 7 corresponds to the test print execution unit.

Further, in step 8, it is determined whether or not a request for resetting the number of copies is made. If the determination is NO, the process proceeds to step 9. In step 9, it is determined whether the set time after the test printing has elapsed. This set time is a timer (not shown)
And the printer unit 3 during this set time.
If it is determined in step 10 that there is the next command in step 10, it is determined in step 11 that there is no cancellation of the actual printing, and if it is determined that there is no reset operation in step 12, In step 13, the paper feeding unit is changed to feed regular paper. In step 14, the operation shifts to the main printing operation. In step 15, the print data stored in the page buffer 10b is cleared. That is, step 1
The determination at 0 corresponds to the actual print execution means, and steps 14 and 15 correspond to the actual print execution means.

If the reset key (not shown) of the operation panel 4 is operated while the printer unit 3 is in the standby state as described above, it is determined in step 12 that the printer has been reset. Then, the process proceeds to the reset at 16, and the page buffer 10b is cleared. This step 16 corresponds to a reset unit.

As described above, the print data transferred from the host computer 2 is stored in the page buffer 10b, and the result of the test print is checked while the printer unit is stopped after the test print is executed. Can be performed, the print data reception from the host computer 2 and the condition setting processing in the printer unit 3 can be performed only once. As a result, the number of operations for requesting print data from the host computer 2 is reduced, and
The transfer time of the print data can be reduced. Also,
Data such as CAD (Computer Aided Design) that has a huge amount of data and takes several tens of minutes to print one page, as seen in the printing of drawings, requires a lot of time to be transferred from the host machine. Even in such a case, the main printing can be resumed by the data developed in the page buffer 10b after the test printing, which is particularly effective. Further, when a defect is found as a result of the test printing, the restarting of printing can be stopped by the reset means, so that waste of paper can be prevented .

If a defect of the test print is found during the period when the printer unit 3 is in the standby state and the operation of the actual print is canceled by the operation panel 4, the actual print is canceled in the step 11. In step 17, only clearing of the page buffer 10b is executed without changing the setting conditions of the printer unit 3. Step 17 corresponds to a main print canceling unit. Thus, in a case of finding a defect in the test printing, it is possible to perform only clearing the page buffer 10b, setting condition of the printer section 3, i.e. Fu揮
Main printing can be interrupted in a state where the setting conditions and the number of copies stored in the memory 7 are maintained. This allows
It is possible to immediately shift to the reception of the next print data .

Furthermore, after the test printing, the result of the test printing is checked while the printer unit 3 is in the standby state, and if no abnormality is found as a result, the operation is left without any operation. Since the set time for standby set by the timer times out, in step 9,
It is determined that the set time has elapsed. In this case, it is also possible to immediately proceed to step 13, change the paper feeding unit to feed regular paper, and then proceed to step 14 for actual printing. Thus, the operation for shifting to the actual printing can be simplified . In this case, step 9 to determine the course of the timer set time corresponds to the print execution instruction means.

Further, as described above, by using the paper feeding unit properly, regular paper is used in the case of actual printing, but in the case of test printing, an irregular paper such as a paper whose back side is printed is used. Can be used to reduce paper waste .

It should be noted that the number of prints for actual printing can be reset by the operation panel 4 while the printer unit 3 is on standby after executing the test printing in step 7. Since this set value is recognized by the CPU 6, step 18
In, the number of print copies can be reset in the printer unit 3.

Next, a second embodiment of the present invention will be described. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description is omitted. The configuration of the controller 1 is the same as the block diagram shown in FIG. Hereinafter, the printing process according to the present embodiment will be described with reference to the flowcharts shown in FIGS. In FIG. 4, initialization is performed at the start,
At this time, the job flag is set. By setting the job flag, the test print mode is set in step 21. This step 21 corresponds to the test print mode setting means in this embodiment.

Thereafter, when the number of copies is set by a predetermined key on the operation panel 4 in step 22, the print data received from the host computer 2 in step 23 is stored in the page buffer 10b in step 24.
Will be expanded to. Next, the process passes step 25 and proceeds to step 26. The processing of step 25 will be described later. Whether or not the job flag is set in step 26 it is determined, if the job flag is judged to have been set, it is determined that the test print mode is set in step 27. If the job flag is determined to be not set, it is determined that the trial print mode is not set, in this case, the process proceeds to the printing operation in step 36.

If it is determined in step 27 that the test print mode has been set, step 2
At 8, the number of print copies is changed to a paper feed unit for feeding irregular paper, and at the same time, 1 is added to the previously set number of print copies (copy counter + 1). Step 28 corresponds to a print copy number adding unit. Subsequently, for a sheet fed from the sheet feeding unit, one test print is executed in step 29, and the job flag is reset. That is, the number of test prints is limited to one. This step 29 corresponds to the test print execution unit in the present embodiment.

Further, in step 30, it is determined whether or not a request for resetting the number of copies has been made. If the determination is NO, the process proceeds to step 31. In this step 31, it is determined whether or not the set time after the test printing has elapsed. This set time is set by a timer (not shown). During the waiting time of the printer unit 3 during the set time, it is determined in step 32 that the next command is present, further it is determined that there is no cancellation of the actual printing in step 33, and in step 34, a reset operation is performed. If it is determined that there is no paper, in step 35, the paper feeding unit is changed to feed regular paper, and in step 36, the operation shifts to the main printing operation, and in step 37, it is stored in the page buffer 10b. Print data is cleared. That is, the determination in step 32 corresponds to the actual print execution instruction unit in the present embodiment, and steps 36 and 37 correspond to the actual print execution unit. If the print data is continuously transmitted from the host computer 2, it is determined that there is next data in step 38, and the process proceeds to step 24. In this case, since the job flag has already been reset, the process proceeds to step 36, and the main printing is executed as long as there is the next print data.

When the reset key (not shown) of the operation panel 4 is operated while the printer unit 3 is in the standby state as described above, it is determined in step 34 that the printer has been reset. At 39, a reset is performed. In this step, the page buffer 10b is cleared, and in step 40, the capture enable flag is reset to prevent the execution of the main printing. Step 39 corresponds to reset means in the present embodiment. At the time of this reset, the page buffer 10b
Only the print data stored in is stored. Accordingly
The job flag (trial
There are no changes to the mode setting conditions).

If a defect in the test printing is found during the period in which the printer unit 3 is in the stopped state and the operation for canceling the actual printing is performed on the operation panel 4, the execution of the actual printing is canceled in step 33. In step 41, the page buffer 10b is cleared, and in step 42, the capture enable flag is reset. In this case, step 41 is a
Corresponds to the cell unit, step 40 and 42, print data storage prohibiting means for prohibiting the store from the upper device (host computer 2) the print data to the page buffer 10b when stopping the resumption of printing after the test printing Is equivalent to This
Is canceled in the page buffer 10b
Only the stored print data is cleared. Accordingly
The job flag (trial
There are no changes to the mode setting conditions).

Further, after the test printing, the result of the test printing is checked while the printer unit 3 is in a standby state, and if no abnormality is found as a result, the operation is left without any operation. Since the set time for standby set by the timer expires, it is determined in step 31 that the set time has elapsed for a predetermined time or more. In this case, it is also possible to immediately proceed to step 35, change the paper feeding unit so as to feed regular paper, and then proceed to the main printing in step 36.

It should be noted that the number of prints for actual printing can be reset by the operation panel 4 while the printer unit 3 is on standby after executing the test printing in step 29. Since this set value is recognized by the CPU 6, step 4
In step 3, the number of copies can be reset in the printer unit 3.

If the elapsed time from the stop of the transmission of the print data from the host machine (host computer 2) to the next transmission is longer than a certain set time, it is determined that the job is a break and the next printing is performed. At the time of data transmission, a job flag is set. When print data of a plurality of pages is transmitted at intervals within a set time, as described above, a job flag is set for test printing of one page, and two sheets of print data of one page are set. No job flag is set for the print data for the first and subsequent pages and for the second and subsequent pages. Thereby, the number of test prints can be reduced, and the operability can be simplified. In addition, as a result of the test printing, when a defect is found and printing restart is stopped, the page buffer 10
Since the storage of the print data in “b” is prohibited and the print data transmitted from the host machine can be read and discarded, it is possible to prevent unnecessary printing from being performed .

In the actual printing, the set number of print copies are printed, but during the process of executing the test printing,
Since 1 is added to the number of copies in step 28,
It is possible to omit the operation of setting the number of print copies for test printing .

Next, the flow of processing of the above-described fetching enable flag will be described with reference to FIG. As shown in FIG. 5A, each time print data is transmitted from the host machine (host computer 2), a reception interrupt routine is executed on the printer side, and it is determined in step 51 that the capture enable flag is set. If so, step 52
At step 53, the print data transmitted from the host machine (host computer 2) is captured (stored in the page buffer 10b). If it is determined that the capture enabled flag has been reset, then at step 53 , The timer interrupt time is reset. The reset timer interrupt time is set when the controller 1 is initialized.

That is, step 61 shown in FIG.
In step 6, the capture enable flag is reset.
In step 2, the host interface 13 is initialized, and in step 63, a timer interrupt time is set. The set time may be a fixed value, or may be updated by the operation panel 4.

Each time the reception interrupt routine is entered, as shown in FIG. 5C, a timer interrupt routine is executed during reception. In step 71, a timer is set each time print data is received, and the next reception is performed. If it is determined that the elapsed time has exceeded the timer interrupt set time, the capture enable flag is set in step 72.

When printing is performed under the same printing conditions as the previous job, the next print result can be predicted from the result of the previous test print. Therefore, as shown in FIG. 6, a routine for determining whether or not the print condition has been changed in step 81 and clearing the job flag in step 82 only when it is determined that the print condition has not been changed is shown in FIG. 25 is replaced. In steps 81 and 82, the test print mode set for each job break is cleared when the print conditions of the currently transmitted print data and the print conditions of the previously transmitted print data are the same, and the actual print is started. This corresponds to a test print mode clear unit to be shifted.

Thus, even when the test print mode is set as a new job, if it is determined that the print conditions are not different from the print conditions of the previous job, the job flag is cleared and the test print mode is set. Since the printing is canceled, it is possible to shift to the actual printing without performing the test printing. As a result, the function of performing test printing only on the first page of a plurality of pages can be effectively used without being affected by the transmission interval from the host computer 2 .
