METHOD FOR DRIVING A DOT MATRIX PRINTER

摘要

The method fractionates dot intervals and drives head pins independantly so as to improve speed of printing and curvature. The method includes a method for generating print enable signal when position of pinhead reaches printing area detected by an edge detector (1), a method for driving monostable vibrators connected to the pins by enabling output signal of a latch (4), and a method for applying interrupt signal to a microcomputer so as to transmit data stored in a line buffer for varying time intervals.
