ABSTRACT:
A printer with mixed base resolution capabilities, having a higher resolution monochrome component such as black and lower resolution components such as cyan, magenta and yellow. The different resolution components are integrated into the same printing mechanism for composite printing of higher resolution black and lower resolution color at the same time. For increased throughput, a higher resolution black printhead has a wider swath.
