Abstract
A printing system is provided for printing an image on a substrate. The image is represented by a set of words with each word including M bits and being modulated so as to produce a single bit stream. The printing system includes a multi-phase clock generator, responsive to a clock signal with a first clock rate, for producing N phase signals and a data serializer, communicating with the multi-phase clock generator, for receiving the N phase signals and the word set. In operation, the data serializer processes each word of the word set, with the N phase signals, to produce the single bit stream, the single bit stream being outputted at a second clock rate with the second clock rate being greater than the first clock rate. The data serializer communicates with a print engine, the print engine receiving the single bit stream for imaging the image on the substrate.
