2.6.3.2 Canon Advanced Printing TechnologyÅ@(CARPS)
Canon Advanced Raster Printing System (hereafter (CARPS) refers to a system of processing data in which printing speed is reduced and operation is made easier
for more user-friendly printing in a Microsoft Windows environment. In CARPS, the following takes place so as to generate output as fast and as easily as possible:
- Instead of converting the print data coming from the application into the printer's page description language (PDL), it turns it into resource data which is GDI-
