ABSTRACT:
A printer is provided comprising a pagewidth inkjet printhead for printing bi-level dots of ink onto print media at a resolution of 800 to 1600 dpi and a controller for controlling the pagewidth inkjet printhead. The controller comprises a receiver for receiving compressed page data to be printed by the printhead, a first decoder configured to decode any compressed continuous tone image planes in the received compressed page data at a resolution of up to 320 ppi in each plane, a second decoder configured to decode any compressed bi-level image planes in the received compressed page data at a resolution of 320 to 1600 dpi in each plane, a half-toner/compositor for creating a composite image by halftoning the decoded continuous tone image planes and compositing the decoded bi-level image planes over the halftoned continuous tone image planes, and a printhead driver arranged to output the composite image to the printhead.
