Abstract
A method and apparatus for controlling firing energy in a printer pen of a thermal inkjet printer are described. A digital voltage value representative of a voltage output by a printer-pen power supply is obtained. The printer-pen power supply is electrically coupled to a switch. The switch is electrically coupled to a nozzle resistor and is controlled using a switch logic signal. A voltage level of the switch logic signal is set based on said digital voltage value and a voltage drop due to a parasitic resistance between the printer-pen power supply and the switch.
