Description

TECHNICAL FIELD The present invention relates to a print control method for printing various patterns by using printing elements having a number of dots in the row direction of a printed character pattern.

(B) Prior Art Generally, the number of dots of the printing element of the printing means is the same as the number of dots in the column direction of the printed character pattern.
Then, as disclosed in Japanese Patent Publication No. 61-59920, when an underline is added to a character for printing as shown in FIG. 6 (a), first, a character pattern to be printed is developed in a pattern buffer. Then, the character pattern is sent to the printing means to perform printing, and after printing, paper feed for the dot number FL in the column direction of the character pattern is performed, then the underline pattern is expanded in the pattern buffer, and the underline pattern is Was sent to the printing means for printing. That is, as shown in FIG. 6C, the character pattern and the underline pattern were printed separately.

In addition, as shown in Fig. 7 (a), a print line (17) for printing characters
And when printing continuous vertical ruled lines between the following lines (18), as shown in Fig. 7 (c), the number of dots in the column direction of the print character pattern, that is, the number of dots FL of the print line (17)
The vertical ruled line pattern of is printed on the print line (17), the number of dots a corresponding to the overlapped portion after printing is subtracted from the number of dots in the column direction FL, and the paper is fed by the number of dots (FL-a). , A ruled line pattern with a dot number 2a, which is twice the dot number a, is printed, the paper is fed by the dot number a, and then the dot number a is added to the dot number S between lines. Was printed, and finally the paper was fed by the number S of dots between lines.

6 (c) and 7 (c), (16) indicates a printing element having a dot number FL.

(C) Problems to be Solved by the Invention In the prior art, when a vertical line is printed between print lines and lines, as described above, three line feeds are used for printing. However, there is a problem in that the print quality is deteriorated because the overlapping portion is formed at a plurality of places as a countermeasure against the broken ruled line.

(D) Means for Solving the Problems The present invention is a print control method for printing a continuous vertical ruled line by overlapping a part of vertical ruled lines, and the number of dots corresponding to the overlapped portion and the dot in the column direction of the print character pattern. When a vertical ruled line having the number of added dots is printed and a vertical ruled line is printed between the print line for printing the character pattern and the line following the print line, A pattern is printed, and after the printing, paper feeding is performed by the number of dots in the column direction of the print character pattern, and then the vertical ruled line pattern of the number of dots obtained by adding the number of dots corresponding to the overlapping portion and the number of dots between the rows The above problem is solved by printing, and feeding the paper by the number of dots between the lines after the printing.

(E) Action In the present invention, when a vertical ruled line is drawn between a print line and a subsequent line, 2
Since only one line feed is required, the printing speed is improved, and at the same time, there is only one overlapping portion for the ruled line breakage countermeasure, and the printing quality is improved.

(F) Embodiment FIG. 3 is a block diagram showing the configuration of a word processor that realizes the print control system of the present invention. (1) stores a character code or ruled line code, and underlines the character code. A text memory in which underline information indicating whether or not to add is stored together, (2) is a print control unit, (3) is a paper feed control unit, and (4) is a line in which the number of dots S of the line interval is set. Interval memory, (5) underline pattern memory, (6) character pattern memory, (7)
Is a ruled line basic pattern memory in which the basic pattern of the ruled line pattern is stored, and (8) is each expansion part for underline pattern, character pattern, and ruled line pattern (9) (10)
A pattern expansion unit including (11), (12) a pattern buffer for storing pattern data to be expanded, (13) a printing unit, and (14) a transfer control unit for supplying the pattern data to the printing unit.

In FIG. 4, (15) shows a printed character pattern, and as shown in the figure, the dot number H of the printing element (16) of the printing section (13) is larger than the dot number FL in the column direction of the character pattern, Here, for the character pattern of 48 × 48 dots,
H is "60". The number of dots in the column direction of the data buffer (12) is set to the number of dots H of the printing element.

Hereinafter, this embodiment will be described in detail with reference to the flowcharts of FIGS. 1 and 2.

First, when a print command is given to the print control unit (2), the print control unit (2) reads code information from the text memory (1), determines whether the code information is a character code or a ruled line code, and uses the character code. If so, as shown in the flow chart of FIG. 1, the character pattern expansion unit (10) is activated, the character pattern corresponding to the read character code is read from the character pattern memory, and the character pattern of 48 × 48 dots is As shown in FIG. 5, the pattern buffer (12) is developed in the upper area (12a). Further, it is determined whether there is underline information of the character code, and if there is a determination, the underline pattern expansion unit (9) is activated,
The underline pattern is read from the underline pattern memory (5) and developed in the lower area (12b) of the pattern buffer (12).

The above expansion processing is performed for each character code in one line of the print line, and when the expansion of the pattern of one line is completed, the pattern data in the pattern buffer (12) is supplied to the print unit (13) by the transfer control unit (14). To do. At this time, the transfer control unit (1
4) sequentially supplies the row pattern of each row that is a combination of the character pattern and the underline pattern to the printing unit (13),
Therefore, in the printing section (13), the character pattern and the underline pattern are simultaneously printed by the H dot printing element (16). After printing, as shown in FIG. 6 (a), the paper feed control unit (3) causes (FL
+ UL + S) = (48 + 12 + 10) dots of paper is fed to prepare for printing the next line. It should be noted that UL represents the number of dots in the column direction of the underline pattern, and S represents the number of dots in the line interval set in the line interval memory (4).

Next, the ruled line printing will be described.

Here, as shown in FIG. 7A, the print line (17),
Line length (18), print line (19), length (FL + S + FL / 2) =
An example of printing vertical ruled lines of (48 + 10 + 24) dots is given.

In this case, based on the vertical ruled line code of the print line (17) read from the text memory (1), the print control unit (2) activates the ruled line pattern developing unit (11) as shown in the flowchart of FIG. Then, the vertical ruled line basic pattern is read from the memory (7), and the vertical ruled line pattern of (FL + a) × FL = (48 + 2) × 48 dots is developed in the pattern buffer (12). The vertical ruled line pattern is supplied from the transfer section control section (14) to the printing section (13) and printed as shown in FIG. After printing, the paper feed control unit (3) feeds the paper for the FL dots. Next, the ruled line pattern development unit (11) develops a vertical ruled line pattern of (S + a) × FL = (10 + 2) × 48 dots in the pattern buffer (12) and supplies this pattern to the printing unit for printing. . Then, after printing, paper feeding for S dots between lines is performed. After this, the ruled line code at the same digit position on the next line is read from the text memory (1), and based on this code, the pattern buffer (12)
A vertical ruled line pattern of FL / 2 = 24 dots is developed on and the pattern is printed. That is, the line feed is required only twice, and the overlapped portion for the ruled line breakage in the printed line (17) and the line interval (18) is only one place.

The character pattern memory may store a character pattern of FL × FL = 48 × 48 dots, or a character pattern of a size larger or smaller than that may be stored for expansion or compression processing. It may be applied to develop an enlarged character pattern of FL × FL.

(G) Effect of the Invention According to the present invention, printing speed can be increased and printing quality can be improved.
