ABSTRACT:
A thermal ink jet printer utilizes a printhead whose electrical connections to the heating elements used to expel the ink droplets has been modified to reduce the effects of parasitic resistance of a first power bus when a number of resistors are simultaneously addressed. The first power bus has been modified by forming and interconnecting to it a second power bus using a low resistance connection which is formed to crossover, or under, a common return. The second power bus is connected at each end to a predetermined voltage, while the first power bus is connected at each end through a series ballast resistor to the same predetermined voltage.
