Abstract
A printing system for making prints from a stream of image data written in a printer page description language is provided. The stream of image data includes a compressed bitmap having break entries dividing the bitmap into a plurality of image data segments. The printing system includes an arrangement for separating the compressed bitmap from the stream of image data and a boundary code catcher, which communicates with the separating arrangement, for creating a table to list the break entries of the bitmap. A memory section is employed to store the bitmap with its corresponding break entry table, and a plurality of imaging channels, which communicate with the memory section, are employed to decompress selected segments of the bitmap in parallel.
