<p>An inkjet printhead assembly (12) includes at least one inkjet printhead (40/240) having an internal power supply path (92/292), a power regulator (100/200) providing an offset voltage (114/214) from the internal power supply path voltage, and multiple primitives (50/250). Each primitive includes a group of nozzles (13), a corresponding group of firing resisters (48/248), and a corresponding group of switches (52/223,224,252). The switches are controllable to couple a selected firing resister between the internal power supply path and the offset voltage to thereby permit electrical current to pass through the selected firing resister to cause a corresponding selected nozzle to fire. <IMAGE></p> |
