Abstract:
A printer for printing rows of ink dots onto a medium, the printer comprising:a scanning carriage for scanning across the medium;a printhead mounted on the scanning carriage, the printhead including a plurality of primitives, each primitive having a plurality of non-staggered nozzles for ejecting ink therefrom and a plurality of ink ejection elements, each ink ejection element associated with a respective nozzle of the respective primitive, each primitive having a primitive size defined by the plurality of nozzles of the primitive;an address select circuit electrically coupled to the ink ejection elements of different primitives and including a plurality of address lines, wherein ink ejection elements of different primitives located at a same position on the ink ejection elements' respective primitives have the same address line; andan advance mechanism for advancing the medium through the printer, wherein the advance mechanism advances the medium by a distance equal to an integer multiple of the primitive size so that ink dots within a row are generated by ink ejection elements associated with the same address line.
