Multiple resolution pagewidth ink jet printer including a positionable pagewidth printbear

A liquid ink printer, depositing ink drops to form an image, in multiple printing resolutions, on a recording medium moving along a recording medium path, comprising:

• a pagewidth printbar, including an array of ink ejecting nozzles spaced at a predetermined resolution, aligned substantially perpendicular to the recording medium path, to eject the ink drops on the recording medium during movement of the recording medium along the recording medium path;
• a positioning device, coupled to said pagewidth printbar, to position said printbar at a plurality of discrete locations;
• a controller, coupled to said printbar, including a plurality of circuits, to control the interaction of said circuits and thereby cause the printer to print at a resolution greater than a fixed printhead nozzle resolution;
• and
• an image input device, coupled to said controller, including a user interface for providing selectable printing resolutions.
