Print control system

Abstract

Abstract PURPOSE:To read data out of a buffer and to print characters, rules lines, graphs, etc., together, by providing a printer control circuit with a processor unit, a control storage part memory, a print buffer, a printer mechanism control circuit, etc. CONSTITUTION:Print data from host equipment 2 are stored in a data memory 14 through a bus interface 11, and the data in the memory 14 are decoded by a processor unit 12 according to a control program in a control memory 13. When received data are character codes, character patterns are read out of a KANJI (Chinese character) pattern memory 3 and then written in prescribed locations of a print output buffer 15. When the data are ruled-line data and graphic data, a form is fed according to a line feed instruction from the equipment 2 and then the ruled-line or graphic data from the equipment 2 are stored in storage area of the memory 14 classified by the ruled-line data and graphic data. According to the control program in the memory 13, they are stored in the buffer 15, whose stored data are read out to print characters, ruled lines and graphs together.
