Abstract

A printer controller for controlling a printhead comprising at least one monolithic printhead module, the at least one printhead module having a plurality of rows of nozzles configured to extend, in use, across at least part of a printable pagewidth of the printhead, the nozzles in each row being grouped into at least first and second fire groups, the printhead module being configured to sequentially fire, for each row, the nozzles of each fire group, such that each nozzle in the sequence from each fire group is fired simultaneously with respective corresponding nozzles in the sequence in the other fire groups, wherein the nozzles are fired row by row such that the nozzles of each row are all fired before the nozzles of each subsequent row, wherein the printer controller is configured to provide one or more control signals that control the order of firing of the nozzles.
