ABSTRACT:
A method for digitally printing a digital image by reference to a succession of code words representing blocks of pixels of the original image. The image is originally subdivided into uniform size blocks of pixels. Each of the blocks of pixels is given a unique identifier unless it is identical to any of the previously scanned blocks. Identical groups are given the same identifier. In printing the digital image, the identifiers are scanned in sequence and the corresponding pixel blocks are successively stored in buffer memories for modulating the printer.
