Wide array printhead module

A printing device comprising:

• a printhead module comprising:
• a plurality of printhead die;
• and
• an application specific integrated circuit (ASIC) to:
• with a delay circuit, calibrate a number of internal delays within each printhead die;
• and
• control activation pulses that activate a number of nozzle firing heaters for each of a number of nozzles, the nozzles being associated with a plurality of primitives, the primitives being defined as groups of the nozzles, wherein the activation pulses are delayed between each of the primitives via the internal delays and a number of external delays to reduce peak power demands of the printhead die,
• wherein the plurality of printhead die are staggered across a width of a print path, where an end of one printhead die overlaps an end of an adjacent printhead die in a direction laterally across the width of the print path.

A method of reducing peak power demands of a printhead module comprising a plurality of printhead die that are staggered across a width of a print path, where an end of one printhead die overlaps an end of an adjacent printhead die in a direction laterally across the width of the print path, the method comprising, with an application specific integrated circuit (ASIC):

• determining a first primitive delay of a printhead die before generating a first activation pulse, each printhead die comprising a plurality of primitives;
• generating the first activation pulse for a primitive of the printhead die, the primitive being associated with a number of nozzles defined within the printhead die;
• activating, via the first activation pulse, a number of nozzle firing heaters coupled to each of the nozzles associated with the primitive based on the primitive delay;
• determining a subsequent primitive delay before generating a next activation pulse;
• and
• generating, based on the subsequent primitive delay, the next activation pulse for a next primitive of the printhead die.
