Abstract
A control system for high speed printers including a low speed microprocessor that processes data input by a one-time serial operation on the data bytes to direct printing operations into a virtual image memory that is a map of the printing sequence for an entire line. A map of the character printing program for each print position is transferred for each character into a print control memory so that printing can proceed as though a large scale high speed computer was in charge of the printing process.
