<p>A signaling method for a pen driver circuit interface is embodied in a signal interface (108) between a controller circuit (102) and a pen driver circuit (104) for a printer (106). At least one signal of the interface is omitted; and the pen driver circuit (104) is modified to process a combination of signals including at least one of the signals on the signal interface (108) to provide information pertaining to the at least one omitted signal. According to a preferred method, the combination of signals are processed when data is not being transferred via the signal interface (108) to provide a pen firing control signal for the printer such as a warm enable signal (708) or a fire enable signal (710). <IMAGE></p> |
