Image data output by printers is generated by CAPT (Canon Advanced Printing Technology Engine Manager) driver software, installed on the host PC, and the printer controller. An advantage of Canon's CAPT technology is its ability to perform GDI commands to data rendering and compression on the host PC, then send this data via the interface to the printer controller memory. The function of the printer controller is to decompress the highly compressed data stored in its memory.
