1. An inkjet printer comprising:
a media transport that passes media through the inkjet printer in a process direction; and
at least three printheads mounted relative to the media transport and the three printheads being aligned in a cross-process direction to form a first printhead module having a first printhead between a second printhead and a third printhead, each printhead having a single ink inlet configured to supply ink to a manifold in the printhead, the manifold being configured to supply ink to at least one array of nozzles in the printhead, the ink inlet of the first printhead is positioned at an end of the first printhead in the cross-process direction that is opposite to an end in which the ink inlet of the second printhead is positioned and opposite to an end in which the ink inlet of the third printhead is positioned in the cross-process direction to reduce a difference in temperatures between ink ejected by the first printhead and the second printhead into a stitch area between the first and second printheads and to reduce a difference in temperatures between ink ejected by the first printhead and the third printhead into a stitch area between the first and third printheads.
