1. A method to compress an image in a printing process, comprising the steps of: providing a first representation of an image to be printed on a printer to a printing pipeline; processing said first representation in said printing pipeline to derive a second representation of said image, said second representation comprising physical printing parameters adapted to said image and said printer; compressing said second representation to obtain a compressed third representation of said image; supplying said third representation to said printing pipeline, and processing said third representation in said printing pipeline to derive a fourth representation of said image; and providing said fourth representation to a printhead of said printer.
