Abstract

Disclosed is a method of multiplexing ink jet drivers where all of the logic is removed from a disposable print head and placed in the printer. This is done without a signifcant increase in the number of leads to the cartridge. Other advantages include increased maximum operating temperature, lower overall cost, and increased immunity to noise generated when switching high heater currents.
