Abstract

A printhead comprising: a first and second elongate printhead modules, the printhead modules being disposed end to end on either side of a join region, wherein the first printhead module and the second printhead module are vertically offset at the join region; and, at least first and second printer controllers configured to receive print data and process the print data to output dot data for the printhead. The first printer controller outputs dot data to both the first printhead module and the second controller; and the second printer controller outputs dot data to the second printhead module, wherein the dot data output by the second printer controller includes dot data generated by the second printer controller and at least some of the dot data received from the first printer controller.
