ABSTRACT:
A printer controller for supplying print data to a pagewidth printhead is provided. The printhead has a plurality of printhead integrated circuits of different lengths arranged across the pagewidth to define the pagewidth printhead having rows of printing nozzles formed by adjacent printing nozzle rows of the adjacent printhead integrated circuits. The printing nozzle rows of the printhead are configured so that there is at least one row for printing each ink color of a plurality of ink colors. The printer controller is configured to transfer the print data to each of the printhead integrated circuits at a rate proportional to their relative lengths so that the print data is transferred to each of the printhead integrated circuits in equal time.
