JPS63206825A - Control system for hard copy by journal printer - Google Patents

Abstract

PURPOSE:To obtain the hard copy of a display picture large in picture width, by dividing the display picture on a display in a horizontal direction, and printing the data of each picture area by outputting to a journal printer in order. CONSTITUTION:The display picture 2 on the display is divided, for example, quarterly in rectangular areas I-IV. In such a case, the width of each of the areas I-IV is formed equal to or less than the maximum width possible to be printed on a journal 5. A head copy control part 3, corresponding to the division of the picture 2, segments each data of the areas I-IV from a displaying buffer memory 1 in order, and stores it in a buffer memory 4 for hard copying, and is printed out. As a result, the data of the areas I-IV of the picture 2 is outputted in a form where they are connected in a vertical direction. By separating the areas I-IV on the journal 5 and rearranging them by corresponding to the picture 2, the hard copy can be obtained.

Description

[Detailed Description of the Invention] [Summary] In an apparatus that is equipped as standard with a journal printer with a narrow print output screen, the display screen of the display with a wide screen width is divided into multiple parts in the horizontal direction, and the journal printer is printed in multiple parts. This allows you to print out a hard copy of the display screen.

[Industrial application field]

The present invention relates to a control method for making a hard copy of a display screen in a device equipped with a journal printer having a relatively narrow print width, such as a terminal device of a POS system.

[Conventional technology]

Generally, a terminal device of a POS system is equipped with a journal printer used for creating receipts and the like. This journal printer typically has a narrow output screen that can be printed, for example, only 24 digits.

On the other hand, the display screen of a commonly used display is 4
The range is from 0 to 60 digits. For this reason, it was not possible to make a hard copy of the entire display screen of the host using the terminal device.

[Problem that the invention seeks to solve]

In devices equipped with conventional journal printers, if the width of the print screen of the journal printer is smaller than the width of the display screen of the display, it has been impossible to make a hard copy of the display screen of the display. In this case, in order to make hard copies possible, it is necessary to separately prepare a printer with a large print screen width, which is a major inconvenience in terms of cost and installation space.

[Means for solving problems]

The present invention enables a journal printer with a narrow print output screen to make a hard copy of the display screen of a display with a large screen.

Therefore, in the present invention, the display screen of the display is divided horizontally into strips with a width that can be printed by a journal printer, and the data of each strip-shaped screen area is sequentially output to the journal printer for printing. I have to.

The printed journal paper is cut into strips and edited, and the data corresponding to the original display screen is restored.

FIG. 1 is an explanatory diagram showing the principle of the present invention.

In the figure, (2) is a display buffer memory with a capacity for one screen.

2 is a display screen of a CRT display.

3 is a hard copy control unit.

Reference numeral 4 denotes a hard copy buffer memory with a capacity corresponding to the print output screen to the journal.

5 is a printed journal.

[Effect]

In FIG. 1, the display screen 2 is illustratively divided into four parts. The individual divided rectangular regions are represented by ■, ■, ■, ■. In this case, the width of each strip-shaped area is set to be equal to or smaller than the maximum width that can be printed on the journal 5.

The hard copy control unit 3 extracts areas from the display buffer memory 1 in accordance with the division of the display screen 2! Each of the data from ~■ is sequentially cut out, stored in the hard copy Batza memory 4, and printed out.

As a result, the data marked ■ in the rectangular area I of the display screen 2 is
The images are printed out on the journal 5 in a vertically connected manner.

A hard copy can be obtained by cutting out the strip-shaped areas (1) to (2) on the journal 5 and rearranging them in correspondence with the display screen 2.

FIG. 2 shows an actual example of a hard copy created in this manner. As shown in the figure, the data distributed on the display screen 2 of the display is divided into four parts, and each divided area is once separated and printed sequentially and independently by a journal printer.

Journal 5 shows the print results. Here, separate each divided area with the paper cut line (shown as a dotted line),
By rearranging in the horizontal direction, a hard copy with the same content as the display screen 2 can be obtained.

〔Example〕

FIG. 3 is an explanatory diagram of the first embodiment of the present invention, in which the hard copy buffer memory 4 is replaced by the display buffer memory 1.
The same size is provided corresponding to each divided area. 11. As in the case of FIG. 1, 11■, ■, and ■ indicate individual divided areas.

In this example, the display puffer memory 1 has a capacity of 80 columns x 24 lines, and is divided into four parts each having a width of 20 columns. In addition, ■, ■, ■, ..., ■, ... in the figure are
It represents the data arrangement for each row and each divided area.

FIG. 4 shows the flow of the hard copy control unit 3 in FIG. 1 when the first embodiment shown in FIG. 3 is used. The control operation will be explained below according to steps (a) to (gl).

(a) Data in display buffer memory 1 for one line (
(in order) read (the first is ■, ■, ■, ■).

(b) Next, divide the number of digits on the display screen by the number of digits on the journal printer to perform area division. If a fraction is found, for example, rounding is performed to make it fit in the final area.

(c+ Data for each divided area (for example, ■, ■, ■,
■) for each corresponding area 1 of hard copy buffer memory 4.
．． A collection of songs is processed to be expanded and stored in II, ■, and ■.

(dl Repeat the above process until the processing queue reaches the final line.

(e) Since the data for one display screen has been developed in the hard copy buffer memory 4, the data for one divided area is read out to the journal printer and printed.

(fl Paper cut the printed area on the journal.

(Phantom) Repeat the processes (8) and (f) until all areas are printed, and then end after printing the final area (IV).

FIG. 5 shows a second embodiment of the invention. In this case, the hard copy buffer memory 4 has the size of one divided area of the display panzer memory l, and is shared by each divided area of the display buffer memory. That is, the hard copy data is buffered four times.

As shown in the figure, the display buffer memory 1 is read out vertically for each divided area (indicated by ■, ■, ■, . . . and ■, ■, ■, . . .). First, data in area I is stored in hard copy buffer memory 4. Next, the contents of the hard copy buffer memo I74 are output to the journal printer, and then the data in the area (2) is stored in the hard copy pamphlet memory 4 and printed for the second time. In this way, the data of each area I, ■, ■, ■ is sequentially printed.

Compared to the first embodiment, this second embodiment has the advantage that the capacity of the hard copy expansion memory 4 is smaller, but on the other hand, the processing time is longer.

〔Effect of the invention〕

According to the present invention, even in a device equipped with only a journal printer with a narrow printing width, it is possible to make a hard copy of a display screen of any size at low cost. , management data, etc. can be easily output and used.
