Memory storage and memory bandwidth requirements of a color laser printer (or other printer having real-time printing constraints) are reduced by representing image information in a compressed format throughout the rendering process. At any one time during the rendering process, preferably, only a single scan line is expanded to the full, uncompressed format required for eventual printing. The rendered scan line is then recompressed and stored in memory. When all scan lines have been processed and are stored in memory in compressed format, the entire image is then expanded in real time and sent to the printer.
