Printing system for media of different sizes

A printing system comprising:

• a media transport system configured to transport media of differing dimensions along a media path;
• a printhead assembly for printing media transported along the media path, the media path having differing widths depending on the dimensions of the media;
• a plurality of service modules for the printhead assembly, each of the service modules being independently rotatable so as to operate in a plurality of different modes;
• and
• a controller for controlling operation of the service modules,
• wherein the controller is configured to operate one or more of the service modules in a first mode and to operate one or more other service modules in a second mode which is different than the first mode, the one or more other service modules extending beyond a width of the media.
