APPARATUS AND METHOD FOR CONTROLLING A PRINTING DEVICE

摘要

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.

1. Apparatus for controlling a printing device, the printing device comprising a first printhead interface for receiving a first printhead, the first printhead for use in applying a treatment fluid to a print medium, and a second printhead interface for receiving a second printhead, the second printhead for use in applying ink to the print medium, the first and second printhead interfaces being consecutively aligned along a common axis, each printhead comprising a respective plurality of nozzles extending in a direction of relative movement of the print medium in relation to said printheads, the apparatus comprising:
a controller arranged to configure activation of nozzles of at least one of the first and second printheads in the direction of relative movement, when said printheads are installed in the printing device, to spatially offset useable nozzles of the first printhead with respect to useable nozzles of the second printhead in said direction.
