Abstract

A printer controller for supplying dot data to at least one printhead module and at least partially compensating for errors in ink dot placement by at least one of a plurality of nozzles on the printhead module due to erroneous rotational displacement of the printhead module relative to a carrier, the printer being configured to access a correction factor associated with the at least one printhead module; determine an order in which at least some of the dot data is supplied to at least one of the at least one printhead modules, the order being determined at least partly on the basis of the correction factor, thereby to at least partially compensate for the rotational displacement; and supply the dot data to the printhead module.
