Abstract
A color printer receives N-bit values indicating a computer generated color to be printed. Each N-bit value has a most significant bit (MSB). Upon receiving the N-bit color values, the color printer creates an address from combined multiple-bit segments of each of the received N-bit values, each multiple bit segment includes at least a MSB of each N-bit value. The color printer includes a cache memory, each cache address including first and second entries. The first entry being values indicative of a computer generated color and the second entry being values usable by the color printer to reproduce a color indicated by the first entry. A processor determines if there is a match at an address created from a received computer color value between the first entry and the received computer color value. The processor is responsive to a determined match to access the second entry at the address and to employ the second entry to control the color printer.
