Abstract

PURPOSE:To shorten printing time, by a system wherein a vertical rule code is detected, a line feed quantity for the next line is set to the number of dot lines constituting one line, then a connection pattern and characters and a vertical rule pattern corresponding to dot lines for the next line are expanded to one line, and are printed. CONSTITUTION:When a vertical rule code is detected, a line feed quantity 15 corresponding to 24 dots of a printing head is designated for the next line, and based on the 24-dot-wide area, a connection pattern 16 for a vertical rule pattern 18 in the preceding line, a vertical rule pattern 17 in the next line and a character pattern B in the next line are expanded to patterns on a line buffer. Resultantly, a pattern-expanding position is shifted by a 2.6-dot amount at a time from the next line, and in some cases residual patterns and the connection pattern for the preceding line and patterns for the next line are simultaneously printed. The number of lines over which the vertical rule pattern is to be continuously extended is counted, and pattern-expanding positions are sequentially set. Accordingly, printing time can be shortened by 44% in the case of 1/6-inch line feeding and 17% in the case of 1/4-inch line feeding.

Description

[Detailed Description of the Invention] [Summary] When printing vertical ruled lines on a form, etc. using a serial printer, the vertical ruled line pattern printed at a specified line interval and the space between the vertical ruled line patterns (hereinafter referred to as line spacing) are connected. However, if only the connected pattern is printed with a line break, it will take twice as long to print as compared to the case where vertical ruled lines are not printed.

When a vertical ruled line code is detected, the present invention sets the line feed amount of the next line to the number of dot lines constituting one line, and compares the connection pattern with the character and vertical ruled line pattern corresponding to the set dot line of the next line. To provide a print control method for vertical ruled lines that expands and prints a line in one line.

[Industrial application field]

The present invention relates to a print control method for outputting pattern data to a serial dot printer and causing the print data to be printed, and particularly to improvements in ruled line connection control.

In recent years, serial dot printers have been used to print ruled lines on forms, etc., but there is a problem in that printing only the connection pattern between lines to connect vertical ruled lines takes twice as long.

Therefore, there is a need for a print control method that reduces the printing time for vertical ruled lines.

[Conventional technology]

FIG. 3(a) shows a block diagram of the print control device.

This print control device edits print data into a predetermined format, converts it into pattern data, and causes the printer to print it. One line of data is read, a pattern is developed in the line buffer 7 with reference to the character pattern generation section 8, and the data is output to the printer 11 with a predetermined line feed amount.

The ruled line consists of the same single digit as the character pattern rlJr
It is printed with a ruled line pattern such as rJ... and a connection pattern that is an extension of that pattern, but the horizontal direction is The connection pattern is developed at the same time as the ruled line pattern, and the connection pattern in the vertical direction is printed on a different line and only that connection pattern is printed.

Below, the printing control of the above vertical ruled lines is shown in Fig. 3 (a), (bl
This will be explained with reference to.

A ruled line pattern such as "1" constitutes print data together with a character code as a ruled line code, and when a ruled line code is detected during pattern development, the connection information table 4 is referred to.

If the ruled line code is instructed to be connected downward, as shown in FIG. Develop the connection pattern 13 using the difference between the length and the line spacing as the line spacing, and create line breaks for the above number of dots!i1
4 to print connection pattern 13.

For example, if the number of dots in the print head is 24 (density 160 dots/inch), the line spacing 1/4 inch is 26.6
Since this corresponds to a dot, the connection pattern is set to 3 dots, and the connection pattern is expanded to the line buffer 7 so that the upper 3 dots of the print head are printed, and the line feed amount is specified as 24 dots for printing.

Note that following line spacing printing, the next line is printed with a line break of 2 or 3 dots.

As described above, the connection pattern of vertical ruled lines is printed separately from the character lines as interline printing.

[Problem that the invention seeks to solve]

As explained above, there is a problem in that the line spacing is printed in order to print the connection pattern of vertical ruled lines, which doubles the number of lines and takes more time to print.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a print control method that improves the printing speed of vertical ruled lines.

[Means for solving problems]

For the above purpose, the print control method of the present invention, as shown in the principle explanatory diagram in FIG. means (25) for setting the vertical ruled line code, and means (24) for developing in one line the connection pattern corresponding to the vertical ruled line code and the characters and vertical ruled line pattern corresponding to the next line dot line; When a code is detected, the connection pattern data, characters, and vertical ruled line pattern data corresponding to the next dot line are output together with the line feed amount to print the vertical ruled line.

[Effect]

As shown in Figure 2 (a), when a vertical ruled line code is detected, the line feed amount for the next line is specified as 15, which corresponds to 24 dots on the print head, and the vertical ruled line of the previous line is placed in the 24 dots. The connection pattern 16 of the pattern 18, the vertical ruled line pattern 17 of the next line, and the character pattern B are developed into a line buffer.

For this reason, the pattern development position is shifted by 2.6 dots (2 or 3) from the next line, and the rest of the previous line, the connecting pattern, and the pattern of the next line may be printed at the same time. Count the number of consecutive lines of the pattern and sequentially set the pattern development position.

As a result, the printing time is 44 mm when using 1/6 inch line feed.
%, it can be improved by 17% when it is 1/4 inch.
