ABSTRACT:
A character generator system for dot matrix printers wherein a microprocessor receives an input signal in the form of an M bit digital code, such as ASCII code, and representing a text to be reproduced in dot matrix form as well as other bits of information. The microprocessor converts the incoming code from an M bit code to an N bit code, where N is greater than M, whereby substantially more information may be transmitted. The microprocessor then sends appropriate information to various components of the system that cooperate to control a dot matrix printer in accordance with the input coded information.
