Abstract
An ink jet printer includes a printhead having a plurality of segments each having ink ejecting nozzles, each segment supplied with ink of a different characteristic. Means are provided for moving the printhead in a direction transverse to the advancing movement of a recording medium. Means are further provided for moving the printhead between two or more positions along the recording medium advance direction. Thus, the printhead can print a swath of ink of a first characteristic from one segment and then be moved to print a second swath from a second segment with ink of a second characteristic. In one embodiment, a printhead has two segments, one printing in black, and the other in color. A shift mechanism is enabled to move the printhead between a black print position and a color print position. The invention contemplates alternate color printing swaths at alternate printing positions along the same printing swath, or a combination thereof.
