ABSTRACT:
An inkjet printer is disclosed with mixed print resolution capabilities. The printed dots have a high resolution monochrome component such as black and lower resolution components such as cyan, magenta and yellow. For increased throughput, a higher resolution black printhead has a wider swath. Various alignments between the printheads and printed dots are disclosed. In one embodiment, the top edges of the smaller color printheads are aligned in a scanning carriage at or near the top of the wider black printhead. In other embodiments, the bottom edges of the smaller color printheads are aligned at or near the bottom of the wider black printhead. In another embodiment, the small color printheads are centered with the wider black printhead.
