Abstract
A method of printing an image with a printhead having spatially offset groups of drop ejectors, each group having a plurality of drop ejectors that are aligned substantially along a scan direction, includes enabling simultaneous firing of drop ejectors that are corresponding members of a first set of groups. Drop ejectors within each group of the first set are sequentially fired until each member of each group has had opportunity to fire. Corresponding drop ejectors of a second set of groups are simultaneously fired, and drop ejectors within each group of the second set are sequentially fired. Any additional groups of drop ejectors are likewise fired until all drop ejectors have had opportunity to fire during a first stroke. Drop ejectors are fired in subsequent strokes similar to the first stroke as the recording medium is moved relative to the printhead along the scan direction until printing is completed.
