Abstract
In a laser printer having a plurality of lasers, each of which effectuates the deposition of toner onto lines of a page to be printed, a method of printing several lines substantially simultaneously comprises storing within a single print data buffer, print data compressed using a predetermined compression methodology. The method also includes decompressing a predetermined segment of said compressed print data by one of a plurality of data de-compressors, each of which is operatively coupled to a laser that effectuates the deposition of toner onto a single line of a media.
