| 1. A print engine controller configured to be coupled with others to drive an ink drop printhead comprising:
an interface at which to receive compressed page data;
image decoders to decode compressed image planes in the received compressed page data;
a half-toner/compositer to composite respective strips of the decoded image planes; and
a printhead interface to output the composite strip to a printhead the printhead interface including:
a multi-segment printhead interface outputting printhead formatted data; and
a synchronization signal generator outputting a synchronization signal to couple print engine controllers to synchronize their
respective strips at the printhead.
