Claim 5:
6. A printing system comprising:
a printhead comprising a plurality of nozzle groups, wherein a nozzle group comprises a plurality of individual nozzles; and
a controller; wherein the controller is to:
cause the printhead to generate a verification plot, the verification plot displaying:
respective differences between a current position of each nozzle group and an aligned position of each nozzle group; and
an indication of an offset to be applied to change the current position of each nozzle group to the aligned position of each nozzle group;

receive an input signal indicating an offset to apply to each nozzle group, the input signal based on the verification plot;
apply the indicated offset to each nozzle group according to the input signal to position each nozzle group at a corrected position; and
cause the printhead to generate a further verification plot, the further verification plot displaying:
respective differences between the corrected position of each nozzle group and the aligned position of each nozzle group; and
an indication of an offset to be applied to change the corrected position of each nozzle group to the aligned position of each nozzle group.
