Abstract

PURPOSE:To make it possible to alter the size of a character at every character, by holding information constituting a printing pattern at every character apart from a character pattern. CONSTITUTION:The character pattern stored in ROM (referred to as a store pattern) is a dot matrix comprising 'number of dot rows stored in ROM(WID)1' X'number of dot lines of store pattern (LEN)4'. Therefore, a printing pattern is 'number of dot rows added to left side of store pattern (SCL)2' X 'number of dot lines of store pattern (LEN)4' and each dot matrix of 'number of dot rows added to right side of store pattern (SCR)3' X 'number of dot lines of store pattern (LEN)4' is additionally constituted as a blank. Hereupon, LEN, SCL, WID and SCR are held as printing pattern constituting informations apart from the store pattern. When the printing pattern is formed, the printing pattern constituting informations are read and the store pattern is mapped thereto to form the printing pattern.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing pattern creation method, and more particularly to a printing pattern creation method in which the size of printed characters can be set for each character.

[Conventional technology]

Various printers are used as output devices for information processing systems. Among such printers, there is a dot matrix printer that expresses a printed character pattern using a dot matrix. The above-mentioned dot matrix printer is suitable for cases where printing of multiple types of characters such as Japanese including Kanji characters is required, so it has become the mainstream of printers these days.

By the way, in the above-mentioned printer, a large number of print patterns are stored in a ROM (read only memory), and when printing, the print pattern is retrieved based on the code of the character to be printed and read out from the ROM. and R
Since each print pattern stored in the OM does not have information regarding the size of its characters, there is a drawback that the size of the characters cannot be changed for each character. In other words, once the size of characters is determined in one character set, all characters in that character set are printed in the same size, and the size cannot be changed. Can not.

[Problem that the invention seeks to solve]

The problem to be solved by the present invention, in other words, the purpose of the present invention is that the size of the printed character can be set for each character by having information that constitutes the printing pattern of that character in addition to the character pattern. The purpose of the present invention is to provide a printing pattern creation method.

[Means for solving problems]

The printing pattern creation method of the present invention uses a dot matrix printer that can change the size of characters to be printed, and includes the following steps: the number of dot rows that include the character pattern, the number of dot rows that will be the left margin of the character pattern, It has print pattern configuration information for each character consisting of the number of dot rows serving as a margin on the right side of the character pattern and the number of dot rows in the vertical direction of the character pattern, and refers to the print pattern configuration information for each character. The printer is configured to include means for determining the size of characters to be printed.

〔Example〕

Hereinafter, a printing pattern creation method according to the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram of a printing pattern according to an embodiment of the present invention. In the figure, the print pattern is constituted by a dot matrix consisting of 4' dot rows (LBN) in one storage pattern and 51 dot columns in one print pattern. And the character pattern stored in the ROM (
The number of dot rows (WID) stored in R0M (referred to as the storage pattern) is 1'
LEN) 4'. As a precaution, the above printing pattern is the number of dot rows added to the left side of the storage pattern (8CL) 2'
X' Number of dot rows of storage pattern (LEN) 4' and number of dot columns added to the right side of one storage pattern (5CR) 3
Each dot matrix of 'X' storage pattern dot row number (LEN) 4' is added as a margin.

In other words, the printing pattern is (LEN)X((SOL)+(
WID)+(SCR)).

At this time, LEN, SCL%WID, and 8CR are held as print pattern configuration information separately from the stored pattern.

When creating a print pattern, the above-mentioned print pattern configuration information is read out, and the stored pattern is matted with it to form a print pattern.

〔Effect of the invention〕

As explained above in detail, according to the print pattern creation method of the present invention, print pattern configuration information is held for each character separately from the character pattern, so the size of each character within one character set is It has the effect of being able to change.

[Brief explanation of drawings]

FIG. 1 is an explanatory diagram of a printing pattern according to an embodiment of the present invention. 1 to 4...Print pattern configuration information.

Claims (1)

[Claims] In a dot matrix printer that can change the size of printed characters, the number of dot rows including a character pattern, the number of dot rows forming a left margin of the character pattern, and the character pattern The character has printing pattern configuration information for each character consisting of the number of dot rows that will be the right margin and the number of dot lines in the vertical direction of the character pattern, and is printed by referring to the printing pattern configuration information for each character. A printing pattern creation method characterized by comprising means for determining the size of a print pattern.
