The effective life of a printhead, such as an ink jet printhead, is extended , when printing repetitive images, by taking measures to change the printhead print elements (e.g. nozzles) that are fired to effect repetitive imaging at a desired location on the media. The nozzles can be changed, yet the repetitiv e images be provided at the same desired location on the media by one or more of : finishing the media after printing to take into account a new position of the images on the media to provide a proper finished media (e.g. by trimming a particular edge or edges); at spaced points in time moving the printhead relative to the media in the second dimension (e.g. substantially transverse to the first dimension); and/or at spaced points in time moving the media in the second dimension relative to the printhead. Where the position of the printhead is moved, that may be accomplished by utilizing a detented shaft, controlled by a knob, that rotates a mounting shaft of the printhead and effects linear movement of the printhead. One detented movement of the detended shaft may correspond to a one pixel movement of the printhead.</SDO AB>
