Abstract

PURPOSE:To print data on a paper of optional size even after specifying the size. CONSTITUTION:When printing data is received (step S1), the received data is edited in a display list of specified size (step S2), and the edited data is stored in a RAM (step S3), and then whether the specified size conforms the size of a preset paper cassette or not is judged (step S4). When the specified size is judged not to conform the size of the paper cassette, a required message for the replacement of cassette is output (step S6), and when an instruction for the replacement of cassette by an operator and forced ejection is not issued (steps S7 and S8) and the instruction for printing data on a paper of preset cassette size is issued (step S9), or a new paper size is specified (step S11), reedition is performed (steps S10 and S12), and then printing is carried out (step S5).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a print control method for a page printer, and more particularly to a print control method for a page printer that prints according to a paper size designated in a document processing apparatus.

[0002]

2. Description of the Related Art Conventionally, in this type of printer, print data received from a host is edited according to a paper size identified by a cassette sensor and a display list is created and printed. If the print data sent contains specified commands that should be edited with different paper sizes, the specified commands have priority and are edited. A message was displayed on the panel that the paper size should be replaced.

In such a case, printing is started by an operator replacing the paper cassette with a paper size requested by the panel display or by the operator designating and inputting forced ejection on the panel. I was doing. Here, as shown in FIG. 4, the display list is an intermediate position before printing in which the development start coordinates for printing a font or the like according to the size of the paper to be actually printed and the start address of the data are stored. Say the language.

[0004]

However, as described above, if the printing is started by exchanging the paper cassette, it means that the paper can be printed only on the paper of the predetermined size after editing. If the print data transmitted from the host includes a command for specifying the wrong paper size, printing will be performed on a paper size different from the size to be originally printed. In addition, if you print forcibly on different size paper, the edit size of the data does not change.Therefore, when you print on a larger size paper, the margins of the paper increase, and on the contrary, the smaller size. When printing on a sheet of paper, the printing will be performed outside the sheet of paper.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a page printer capable of printing on paper of an arbitrary size even after editing to a designated size. A print control method is provided.

[0006]

In order to achieve the above object, a print control method for a page printer according to the present invention edits print data into a display list (intermediate language) of a designated size, and sets a preset paper. It judges whether or not the size of the cassette matches the specified size.If it does not match, a cassette replacement request message is output, and then the display list edited to the specified size is re-edited according to the re-edited size. Editing is performed, and printing is performed based on the display list after the re-editing. Here, the re-edit size is the size of a preset paper cassette or the newly designated paper size.

[0007]

In the page printer, after the print data is edited in the display list of the designated size and the size of the preset paper cassette does not match the designated size, the cassette replacement request message is first output. If the operator replaces the cassette with the required size, print on the paper in that cassette,
If the operator gives an instruction for forced ejection, the printing is performed as it is.

On the other hand, when the operator issues an instruction to print on the paper of the cassette set in advance, or when a new paper size is specified, the display list edited once is stored in the cassette set in advance. Re-edit according to the size or the newly specified paper size. Then, printing is performed based on the display list after re-editing. As a result, for example, even if the print data is sent to the page printer with the wrong paper size, the data once received by the page printer is reused, the page size is re-edited, and the requested paper size is printed again. be able to.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a flow chart showing the flow of processing of a print control method according to the present invention, and FIG. 2 is a block diagram showing an example of the configuration of a document processing apparatus to which the print control method according to the present invention is applied. First, in FIG. 2, print data including a command for specifying a size to be edited is transmitted from the host 10 to the page printer 20.

In the page printer 20, the host 1
The print data transmitted from 0 is received by the I / F control circuit 21. The received print data is edited by the microprocessor 22 according to the edit size by the designated command included in the data, and stored in the RAM 23 in the form of a display list as shown in FIG. The microprocessor 22 executes the above-described processing such as editing according to a program stored in the ROM 24 in advance.

On the other hand, the size of the paper cassette (not shown) preset in the page printer 20 is detected by the paper cassette sensor 25. This size information is sent to the microprocessor 2 via the I / O control circuit 26.
Given to 2. The microprocessor 22 determines whether or not the size of the paper cassette and the edit size of the display list match, and if they match, the printing operation is directly performed, but if they do not match, the panel 27 is used.
A process for outputting a cassette replacement request message is performed.

The panel 27 has a display section for displaying a cassette replacement request message, and a key for the operator to instruct the display list to be forcibly ejected when the display is made, and a preset sheet. A key for instructing printing on the paper in the cassette and a key for newly specifying the paper size are provided.

Next, the processing procedure of the print control method according to the present invention executed by the microprocessor 22 in the page printer 20 having the above-mentioned configuration will be described with reference to the flowchart of FIG. When the print data transmitted from the host 10 is received by the I / F control circuit 21 (step S1), the received data is edited (step S2), and a display list is formed in a size designated by a command included in the received data. And stores it in the RAM 23 (step S3).

Next, it is judged whether or not the size of the edited display list and the size of the paper cassette detected by the paper cassette sensor 25 match (step S).
4) If they match, the printing operation is performed as it is (step S5). On the other hand, if they do not match, a cassette exchange request message is output to the panel 27 and the request message is displayed (step S6). In the state in which the request message is displayed, the microprocessor 22 temporarily stops the series of processes and enters a standby state waiting for the process by the operator.

In this standby state, when the operator replaces the paper cassette with the size of the request message (step S7), the process returns to step S4 to detect the size coincidence again, and shifts to the printing operation of step S5.
When the operator does not replace the paper cassette and instructs the forced ejection by the key input on the panel 27 (step S8), even if the edited size and the size of the paper cassette do not match, the process proceeds to step S5. To force the printing operation.

This process is the same as in the conventional example, and when a paper cassette larger than the size of the request message is set, the blank area of the printed paper increases, and conversely the smaller paper. When the cassette is set, printing is performed by protruding from the paper. On the other hand, when the operator instructs to print on the paper of the preset cassette by key input on the panel 27 (step S9), the edited data is re-edited (step S10).

That is, in step S10, as shown in FIG. 3, the old display list already created in the RAM 23 is edited by calculating the X coordinate and the Y coordinate to the size of the preset paper cassette. Then, a process for newly storing the new display list in the RAM 23 is performed. As a result, in step S5, the RAM2
The printing operation is performed based on the new display list stored in 3.

While the operator is in the standby state for processing, the operator does not replace the paper cassette, does not instruct the forced ejection, and does not instruct the printing of the paper in the set cassette. Even when a new paper size is designated (step S11),
Similar to the process in step S10, the created old display list is re-edited into a new display list of a newly designated size (step S12), and then the process proceeds to step 5 to create a new display list. The printing operation is performed based on the above.

In the above embodiment, in the standby state for processing by the operator, there are provided two types of re-editing functions for re-editing with the preset cassette size or a new designated size as the re-editing size. Although the case has been described, only one of the functions may be provided. Further, in the case where only the re-editing function for preset cassette size is provided, in the above-described embodiment, the re-editing process is performed by the key input by the operator. If not, it is possible to automatically shift to the re-editing processing for the preset cassette size.

[0020]

As described in detail above, according to the present invention, print data is edited into a display list of a designated size, and whether or not the size of a preset paper cassette matches the designated size. If it is determined that they do not match, a cassette replacement request message is output, and then the display list edited to the specified size is re-edited according to the re-editing size, and based on this re-edited display list. Since printing is performed, it is possible to print on a sheet of a desired size even after editing to a designated size.

Thus, for example, when the print data is transmitted to the page printer with the wrong paper size,
Since the page printer can reuse the print data once received and re-edit it to the required paper size, it is not necessary to retransmit the Indian data from the host, which saves time and paper. Further, even if the size of the paper cassette to be set is wrong, it is possible to print without wasting paper.
