Abstract

본 발명은 도트매트릭스 프린터의 인자처리방법에 관한 것으로, 종래에는 한글/한자에 언더라인을 할 경우 문자와 언더라인의 겹침이 발생하고 언더라인의 종류가 적어 사용자들이 사용할수 있는 문자인자 형태의 폭이 단순해지는 결점이 있었다.The present invention relates to a printing method of a dot matrix printer. In the prior art, when an underline is placed in a Hangul / Hanja, overlapping of characters and underlines occurs, and the types of underlines are small so that the width of a character factor type that users can use There was a drawback to this simplicity.

이와같은 종래의 결함을 감안하여 본 발명은 문자와 언더라인의 겹침을 방지하기 위하여 라인피드(Line Feed)를 한 후 언더라인을 프린트할 수 있도록 하고, 직선언더라인을 두줄 프린팅하게 하여 특히 강조하고자 하는 문자에 인자할 수 있도록 하였다.In view of the conventional defects as described above, the present invention allows to print the underline after line feed in order to prevent the overlap of characters and the underline, and to emphasize the two lines by printing the underline in particular. It is possible to print to the character.

Description

How to handle double line underline by character of dot matrix printer

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 도트매트릭스 프린터의 시스템 구성도.1 is a system configuration diagram of the dot matrix printer of the present invention.

제4도는 제1도에 대한 문자별 두줄언더라인 인자형태도.4 is a two-character underline printout pattern for FIG.

제5도는 제4도에 대한 두문자 두줄언더라인 인자형태도.5 is an acronym two-line underline argument to FIG.

Claims

Font ROM (1) containing character data, Font RAM (2) (3) for storing actual font data values of the font ROM (1) as modified data, Computing device (4) and internal room ( 8), a multiplexer 7, a data buffer 5, and an address buffer 6, each of which has a central unit 11 for transforming font data, sets underline flags 1 and 2 for input data. After saving the data in the input buffer and buffering the input data until the number of data to be printed on the line is the same as the number of input data, the font data is called from the font ROM (1), loaded into the print buffer, and printed. When line feedback (LF) is performed at the time of setting the underline flag, the print buffer end address and the start address are loaded into the register (EA) (HL), respectively, and the register (B) value is loaded to logically match the start address. HL) to the print buffer After storing, increase the address and store the register (HL) in the print buffer. If the address is increased and the register (HL) is larger than the print buffer and address (EA), move the register (HL) to the printer buffer and address (EA). Two-line underline print processing method for each character of the dot matrix printer characterized in that the processing.
