1. A printer controller configured to generate dot data for supply to a pagewidth printhead which includes at least a first printhead integrated circuit and a second printhead integrated circuit arranged adjacent each other either side of a join region, the first and second printhead integrated circuits having different lengths which aggregate in said adjacent arrangement so that the first and second printhead integrated circuits extend across said pagewidth, the printer controller configured to transfer dot data to each of the first and second printhead integrated circuits at a rate proportional to the relative lengths of the first and second printhead integrated circuits so that the dot data is transferred to each of the first and second printhead intergated circuits in equal time.
