1. A method for synchronizing a plurality of pixel generation mechanisms on a corresponding plurality of print engines comprising the steps of:

  • providing a plurality of print engines, each of the print engines including a pixel deposition mechanism, the pixel deposition mechanism having a pixel deposition clock signal for providing a pixel deposition frequency for the pixel deposition mechanism;

    embedding a first clock signal in data so as to produce a combined data and clock signal;

    communicating the combined data and clock signal to each of the print engines;

    deriving the first clock signal from the combined data and clock signal by each of the print engines; and

    generating the pixel deposition clock signal for each of the plurality of pixel deposition mechanisms by each of the print engines;

    whereby the pixel deposition frequency of each of the plurality of pixel deposition mechanism are generated from the first clock signal.
