A method and apparatus for transmitting data to a printhead by moving a carriage while the printhead records on a receiver medium. The printhead includes a plurality of recording elements and first electronic circuitry is also mounted with the printhead on the carriage for bi-directional movement with the carriage. An optical data link is coupled to the first electronic circuitry. The optical data link carries image data signals from second electronic circuitry remote from the carriage. A multiplexer multiplexes image data signals for transmission to the optical data link. The first electronic circuitry on the carriage includes a demultiplexer that demultiplexes the image data into signals for operation of the printhead.
