Abstract
An fluid ejection device includes nozzles and includes firing resistors which correspond to the nozzles. Each firing resistor and corresponding nozzle are located in zones on the fluid ejection device where each zone has at least one firing resistor and corresponding nozzle. Addressable select logic responsive to a select address couples fire pulses to the firing resistors in the zones so that each firing resistor in each zone is coupled to the same fire pulse.
