Abstract:
A fluid ejection device comprising:an internal power supply path configured to provide a substantially constant voltage; nozzles; firing resistors, wherein each firing resistor corresponds to a corresponding one of the nozzles, wherein each firing resistor and corresponding nozzle are located in one zone of a plurality of zones on the fluid ejection device, and wherein each zone has at least one firing resistor and corresponding nozzle; addressable select logic responsive to a select address to couple multiple fire pulses to the firing resistors in the zones so that selected firing resistors in the same zone are coupled to a same fire pulse, wherein the same fire pulse controls an initiation and a duration in which the selected firing resistors in the same zone are coupled to the internal power supply path to thereby control fluid ejection from the nozzles in the same zone corresponding to the selected firing resistors; and at least two parallel and adjacent feed slots, wherein the nozzles are disposed on the fluid ejection device to be adjacent to the feed slots on either a first side or a second side of the feed slots, wherein each zone is defined to include only the nozzles in fluid communication with the adjacent feed slots.
