摘要： A novel method and system for operation in combination with a laser printer for expanding its character and typeface selection capability. The sequence and operation for this method and system include dividing a list of characters to be printed into a plurality of character groupings or collections, storing these character groupings or collections in a plurality of different memories or memory sites, and providing an input command signal to these memories or memory sites which corresponds to a selected character desired to be printed. The different memories or memory sites are addressed starting first with the memory or memory site storing the largest character grouping or collection having the most frequently used characters therein and then addressing the different memories or memory sites in sequence to or toward the memory or memory site storing the smallest number of less-frequently used characters therein. In this manner, the memory storage capability and computational speed of the laser printer are maximized, and the price/performance figure of merit and reliability of the printer are also maximized.
