Abstract
In order to overcome inefficient power dissipation in parasitic resistances and to provide economies in the power supply, a higher resistance value heater resistor is employed in a thermal inkjet printhead. Higher current densities in a high resistance segmented heater resistor are reduced by employing a shorting bar divided by a current balancing resistor.
