Abstract

PURPOSE:To print printing data for two pages transmitted from a host device on a surface of printing paper by providing a page feed code conversion means alternately converting format feed control codes into two types of internal control codes, i.e. an internal code not instructing a paper feed but a page feed and an internal code instructing both a page feed and a paper feed, and a page combining means controlling a printing part by said internal codes. CONSTITUTION:A page feed code conversion means 22 alternately converts format feed control codes transmitted from a host computer 1 by a setting switch 21 to two types of internal page feed control codes, i.e. a second 'a presence of paper feed' and a first 'absence of paper feed'. With the first internal code, a page combining means 41 only discriminates a data group 51 for one page from a succeeding data group 52 and does not instruct a printing part to conduct a print-out and a paper feed. With the second internal code, it arranges the data groups 51 and 52 for two A-5 size pages across the just preceding first internal code on a surface 50 of A-4 size printing paper and instructs the printing part 50 to conduct a print-out.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a page printer, and particularly to a method for controlling printing and paper feeding.

(Prior art) Conventional page printers convert all format feed (FF) codes sent from host devices into internal codes that instruct a page break and paper feed as control codes for page feed and paper feed. Therefore, on one side of the printing paper,
One page was being printed as set in the host device.

Note that some word processors have a function that allows you to print two pages on each side of printing paper as "Fukutoshi Printing J," but this function is all set in the host device, and for page printers, Control code 1 for format feed by combining two pages into one page of data
The operation for the control code of the page printer is exactly the same as in the case described above.

[The problem that the invention attempts to solve]

In the conventional page printer described above, before operation starts, settings such as loading printing paper and specifying the print position range are made on the printer side, but after operation starts, all printing operations are controlled by control codes sent from the host device. One page of printing paper set in the host device is printed on one side of the printing paper, so if the preset printing paper size is the same size as column A or column B, etc. Even if the device is capable of printing two pages, as shown in Figure '84, only one page can be printed, and if two types of printing processing are being mixed, the page printer It is necessary to redo the settings on the printer side and replace the paper, or to change the programs, operations, etc. on the host device side in accordance with the printing paper, and there is a drawback that the settings must be changed frequently.

An object of the present invention is to switch the printing paper size on the page printer side and print when the printing paper size of one page set in the host device is half the size of the printing paper installed in the page printer. To provide a page printer capable of printing out two pages of print data set in a host device on each side of a sheet of paper.

(Means for Solving the Problems) The page printer of the present invention has a first internal code that does not feed the paper with only a page break, and a first internal code that does not feed the paper with a page break and paper feed, each time it detects a format feed control code sent from a host device. a page break code conversion means that alternately converts the page break code into a second internal code;
The print data group between the internal code of The page combining means instructs printing output and paper feeding, and the setting means allows external setting of execution or non-execution of the page break code conversion means.

(Function) When the format feed control code sent from the host device is converted into an internal code, the first
The first internal code does not feed the paper, and the second internal code arranges the print data on the surface of the printing paper and outputs it. Therefore, two pages worth of print data sent from the host device are printed on one surface of the printing paper.

Furthermore, if the above-mentioned page break code conversion is not performed, by switching the setting means, it is possible to set the print output on one page of printing paper to one page set by the host device.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the page printer of the present invention, FIG. 2 is a flowchart showing the processing of the page break code converting means 22, and FIG. FIG.

The page printer of this embodiment includes a code conversion circuit 2 including a new page code conversion means 22 and a setting switch 21, a memory 3, a print control circuit 4 including a page combination means 41, and a printing section 5.

The page break code conversion means 22 converts the host computer 1 when set from the outside by the setting switch 21.
A flip-flop (not shown) whose logic output is alternately inverted to 0 and 1 depending on the format feed control code sent from
, and alternately converts the format feed control code into two types of internal codes for page break control: the second ``with paper feed'' and the first ``no paper feed.''

At the time of the second internal code, the page combining means 41 prints two groups of print data before and after the second internal code! J3
As shown in the figure, two adjacent pages on one side of the printing paper
The paper is arranged as a page, and the printing unit 5 is controlled to perform the operation of feeding the paper after outputting the printout.

Next, the processing of the page break code conversion means 22 will be explained with reference to FIG.

First, the output of the flip-flop is set to logic 0 (
Step 101). The print data from the host computer 1 of the host device is read (step 102), and the print data other than "form feed" and "end" are directly converted into internal data and stored in the memory 3 (step 109).
). Step 1: If the code for "Form forwarding" is detected,
03), the flip-flop is inverted, step 104
), when the output of the flip-flop is 1, the code of the detected "form feed" is converted to the first internal code (step 106), and when the output of the flip-flop is 0, the code of the detected "form feed" is converted to the first internal code. The code is converted into a second internal code (step 107), and all converted internal codes are stored in the memory 3. When the "end" code is detected (step 108), it is converted into an internal code and sent to memory 3, and the process is ended (step 1
10).

Next, the processing of the page combining means 41 and the printing section 5 will be explained with reference to FIG.

As described above, in the case of the first internal code, the page combining means 41 simply treats the previous data group 51 as one page and distinguishes it from the subsequent data group 52, and neither prints output to the printing section nor feeds the paper. Without any instruction, the data group 51 and 52 for 2 pages of ^5 size are arranged on one side 50 of the ^4 size printing paper, and the first internal code immediately before the second internal code is inserted. Print out from step 5. Furthermore, if the print data for the last side of the printing paper is only for one page sent from the host computer 1, '!' after the first internal code! One internal code of J2 will be missing, but in such a case, the end of text (ETX) that immediately follows,
A code indicating an end such as end of transmission (EOT)
One blank page corresponding to the data group 52 of the next page is added to form one side of the printing paper, and after printing is output from the printing section 5, the paper is fed and the process is completed.

When the dimensions of the printing paper surface for one page set in the host computer 1 match the dimensions of the printing paper installed in the printing section 5, and when printing one page on one paper surface, turn off the setting switch 21. As a result, the logic output of the flip-flop is fixed at O, and when a format feed code is detected, it is all converted to the second internal code. The page combining means 41 arranges the print data group delimited by the second internal code as one page on one side of a predetermined printing paper, and the printing unit 5 performs printout and paper feeding for each page, that is, for each page. .

The size of the printing paper loaded in the printing unit 5 is determined by the size of one page set by the business program of the host computer 1, so if the loaded printing paper is 84 size and the business program setting is ^5 size. or A4
When printing two pages on one sheet of paper when the standard series is different, such as size, use the printing enlargement or reduction function, or replace the printing paper with one of the standard series set by the business program. It can be implemented by

In addition, when the business program of host computer 1 is set to 1 page per page, if you want to perform "bag binding" printing of 2 pages per page, the By installing standard-based printing paper, setting the print position of the front and back pages toward the center, and turning on the setting switch 21, you can reduce the printing time and print data in one piece without changing the business program. It is possible to print out ``bags''.

〔Effect of the invention〕

As explained above, the present invention alternately distributes the format feed control code sent from the host device into two types of internal control codes: an internal code that only causes a page break but does not feed the paper, and an internal code that causes both a page break and paper feed. By providing a page break code converting means for converting and a page combining means for controlling the printing section using these internal codes, the size of the printed paper surface of one page set in the host device can be adjusted to the size of the printed paper surface of one page set in the host device. When the area is half the size of the printing paper, it is possible to switch on the page printer side and print out two pages of print data set on the host device on one side of the printing paper, making it easier to replace the printing paper. This has the effect of saving resources such as time and inventory of printing paper according to size specifications.
