Abstract
An image generation system includes a data processor for carrying out data processing operations along with a read only memory (ROM) and random access memory (RAM). A bus bar interconnects the various units to establish a flow of commands and data. A floppy disk controller operates as an interface for a floppy disk drive and a direct memory access controller controls the floppy disk controller for the transfer of data to the RAM. A serial communication controller serves as an interface between the flow of data from the image generation system to a printer engine. A bit-map means operates for storing, addressing and re-organizing data for normal and duplex printing.
