Abstract
A printhead with drive circuitry for a heating element. At least part of the drive circuitry is positioned proximate to and within 60 microns of the heating element. Moving the drive circuitry within 60 microns of the heating element enhances the nozzle packing on the printhead substrate and improves its energy efficiency.
