A method of determining the state of a printheadcartridge in a thermal inkjet printer. As a result, there is more continuity of packaging, and fewer glued sides. IP packets are also routed within a second ISP’s domain from single network device with a second database. A hysteresis unit is coupled to the AD converter for generating a pulse in response to a power threshold being crossed and a load switch control unit is coupled to the hysteresis unit and the at least one power amplifier for providing gain and phase compensation in response to the pulse.
