Control system for dot matrix printer.

摘要

A control system for a dot matrix printer (10) having control means (52) for controlling the speed of lateral movement of a print element relative to record media. The control system includes a memory (70) for storing a memory signal representative of the presence or absence of a printing operation by said print element prior to a subsequent printing operation by said print element. The control system also includes print inhibiting means (54,58,64) coupled to said memory (70) and adapted to compare a print command signal with said memory signal and to output a signal forbidding the subsequent printing operation by said print element when it receives a print command signal following the previous printing operation. The effect of this control system is to inhibit continuous printing of dots in every dot position in the lateral direction for those characters which can be printed with dots in every other dot position to increase the lateral speed of said print element relative to said record media. <IMAGE>
