ABSTRACT:
A data transmission system and method is provided for furnishing data to respective drivers for a multicolor sparse array non-impact recording head that includes plural sets of recording elements for sequentially exposing a single pixel area on a recording medium. In one recording mode each recording element of a set of recording elements for recording one color is provided with the same color component exposure data to sequentially control enablement of the plural recording elements at the pixel area. In a second mode at least one of the recording elements of the set is disabled from recording at the pixel area whereas at least one other recording element of the set is enabled to record with a color component exposure at the pixel area.
