Abstract

PURPOSE:To eliminate the conversion from character code to bit image in a computor, improve memory efficiency, reduce the processes in the computor and shorten the processing time. CONSTITUTION:A control part 3 is provided between a computor 1 and a printer 2 to control a rule mark printing and a memory 4 is provided to temporarily store exogenous character data in the control part 3 in order to send the rule mark and the exogenous character data from the control part 3 to the printer 2 by the character code and change line feed amount or printing position, thereby controlling the rule mark printing.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruled line printing control method when printing ruled lines with a printer.

0002

[Prior Art] Conventionally, when printing ruled lines on a printer, the conventional method is to convert a character code into a bit image on the computer side, and then download the converted bit image to the printer. It is.

0003

[Problem to be Solved by the Invention] However, in the conventional method, when printing ruled lines, a bit image is downloaded from the computer side to the printer.
It is necessary to convert the character code to a bit image on the computer side, and the huge amount of converted data must be stored inside the computer. Therefore, data transfer takes time, and data conversion processing takes too much time.

[0004] Therefore, the present invention aims to eliminate the conversion process from character code to bit image inside the computer, improve memory efficiency, reduce the processing load inside the computer, and shorten the processing time. With the goal.

[0005]

[Means for solving the problem] By providing a control section between the computer and the printer to control the printing of ruled lines, and providing a memory for temporarily storing the external character data in this control section, the external character data in the memory can be stored in the memory. The controller generates character data, sends ruled line and external character data to the printer in character code, and controls the printing of ruled lines by changing the line feed amount and printing position.

[0006]

[Operation] In the above method, when printing ruled lines,
There is no need for bit conversion on the computer side, and there is no need to have a huge amount of bit image data. Furthermore, since the internal processing of the computer is reduced, the processing time for printing ruled lines can also be shortened.

[0007]

Embodiment FIG. 1 shows a configuration diagram of this embodiment. In this embodiment, a control section 3 for controlling the printing of ruled lines is provided in the interface section of the printer 2, a memory 4 for temporarily storing external character data is provided in the control section 3, and the control section 3 controls the printing of the printer 2. Data for ruled lines and external characters is sent using character codes, and printing of ruled lines is controlled by changing the line feed amount and printing position.

[0008] In printing by the printer 2 in this embodiment,
As shown in Figure 3, the character code for the ruled line is JIS code, 24 dots (8) x 24 dots (9), and the character spacing is 3 dots (10) to the right of the character, and the line feed amount is
The dot width from the current printing position 13 to the next line printing position 14 is set as 30 dots (12), and the external characters are defined as external characters 5, 6, and 7 in FIG.

The ruled line code with the same line thickness is shown in FIG.
As shown in the figure, there are basically 11 types of ruled line codes 14 to 24. Therefore, in the printing process,
The control unit 3 receives print data from the computer 1 in character code, checks whether ruled line codes 14 to 24 are present in the character code, and determines whether ruled line codes 14, 16, 19, and 20 are present. For example, if a ruled line code 17, a ruled line code 18, and a ruled line code 21 exist, the external character 5 is changed to a ruled line code 15.
, ruled line code 22, and ruled line code 23, the external character 7 is used as external character data.If the code is other than that, the space code is stored in the memory 4 in the control unit 3 and the combination processing is performed when printing. By doing this, you can print ruled lines.

Next, the combination processing will be explained based on FIG. 4. X1 to X4 in FIG. 4 are normal printing start positions for each line, and Y1 to Y4 indicate positions shifted 6 dots downward and further shifted 3 dots to the right from the print start position of each line.

[0011] Line feed is performed using a line feed code, and the character code of the ruled line is printed until the line feed code, that is, the code at the end of the first line (X1) is reached, and when the line feed code is reached, it is shifted 6 dots downward. Next, by shifting the print position 3 dots to the right, the print position becomes Y1,
It is inserted between ruled line characters. Therefore,
The external character codes stored as external character data for the ruled line code are printed in sequence for the number of printing columns for the ruled line. Then, by performing a line feed of 24 dots, which is the number of dots in the character, the printing position is changed to the normal printing position. This is the printing position of line (X2). Furthermore, the memory 4 that stores the private character data is overwritten line by line to improve memory efficiency.

By repeating the above process, ruled line printing is performed.

[0013]

[Effects of the Invention] As explained above, according to the present invention,
When printing ruled lines, there is no need for bit conversion on the computer side, and there is no need to have a huge amount of bit image data, leading to improved memory efficiency. Also,
The burden on internal processing is reduced and processing time is shortened.
