Abstract
A method of making a printhead comprises forming a resistor strip in a heating region of the printhead. In a first portion of the heating region, a resistive layer is formed including a central resistor region interposed between two spaced apart conductive elements. In the method, a conductive layer is removed from a bus region of the printhead while protecting the first portion of the heating region.
