Abstract
A printhead is provided having a plurality of rows of nozzles, with the nozzles in each row being grouped into fire groups, and a controller configured to fire the nozzles of each fire group by outputting firing pulses to the nozzles. The controller sets the number of fire groups in each row based on the width of the firing pulses and a predetermined length of time for firing all of the nozzles of that row.
