Abstract: According to one example, a printer includes an inkjet printhead, and the printhead comprises nozzles through which printing fluid is ejectable during a pass of the printhead across a print zone. Processing printhead control data includes obtaining printhead control data describing pixel locations in an image to be printed on a media, and allocating, for a swath of the image, each of the pixel locations to a printhead nozzle and to a print pass of a set of print passes in accordance with a print mask. The print mask defines sections associated different groups of the nozzles.

Abstract: An apparatus and method for controlling a printing device are described. In examples, a printing device has a first printhead interface, a first printhead for use in applying a treatment fluid to a print medium and a second printhead interface, a second printhead for use in applying ink to the print medium. The first and second printhead interfaces are consecutively aligned along a common axis and each printhead has a plurality of nozzles that extend in a direction of relative movement of the print medium in relation to said printheads. An example apparatus then has a controller arranged to, when the printheads are installed, configure activation of nozzles of at least one of the first and second printheads in the direction of relative movement to spatially offset useable nozzles of the first printhead with respect to useable nozzles of the second printhead in said direction.
