| 1. An inkjet printer system comprising:
a pagewidth printhead comprising at least two integrated circuits of different lengths arranged across the pagewidth to define
the pagewidth printhead having at least one row of inkjet nozzles for printing one ink color formed by adjacent inkjet nozzle
rows of the adjacent integrated circuits; and
a controller configured to transfer print data to each of the integrated circuits of the printhead at a rate proportional
to their relative lengths so that the print data is transferred to each of the integrated circuits in equal time.
