First Claim
1. An ink drop printer driven by a print engine controller comprising:
- an interface at which to receive compressed page data;
a contone image decoder to decode any continuous tone image planes in the received compressed page data;
a bi-level decoder to decode any bi-level image planes in the received compressed page data;
a half-toner/compositor to dither any continuous tone image planes and composite bi-level image plane data with any dithered image plane;
a print head driver to output the composite to a print head; and
a print head,wherein the contone image decoder outputs separate color planes of the decoded continuous tone image planes to separate buffers in a front end to the halftoner/compositor.
