A first method obtains a printer having a single-printhead horizontal resolution of H dpi. Dots are printed using first and second printheads in the same print pass. The first printhead is enabled and the second printhead is non-enabled during a first portion of a carrier-movement distance equal to 1/H, and the second printhead is enabled and the first printhead is non-enabled during a second non-overlapping portion of such distance. A printer and a printhead driver for performing the first method are described. A second method obtains a printer having a single-printhead resolution of H horizontal dpi by V vertical dpi. First print data for the first printhead and second print data for the second printhead of H/2 horizontal dpi by V vertical dpi are obtained, are horizontally interlaced creating H horizontal dpi by V vertical dpi, and are printed using the first and second printheads in the same print pass.
