Inkjet printer having spaced nozzle firing sequence

摘要

An inkjet printer comprising: an array of nozzles arranged into rows, each row consisting of a plurality of nozzle groups, the nozzles in each group being interspersed with nozzles from the other groups; and associated drive circuitry for actuating the nozzles in the row in accordance with a firing sequence, the firing sequence enabling the nozzles in each group to eject printing fluid simultaneously, and enabling each of the groups to eject printing fluid in succession. The nozzles in each group are spaced from each other by at least a predetermined minimum number of nozzles and each of the nozzles in a group is spaced from the nozzles in the subsequently enabled group by at least the predetermined minimum number of nozzles.
