One method operates a printer-controller application specific integrated circuit (ASIC) by applying a predetermined voltage to an analog input pin which identifies a desired operating mode (such as, but not limited to, one of at least several test modes) of the ASIC. An analog-to-digital converter (ADC) converts the voltage to a digital output which is used to configure the ASIC to operate in the desired operating mode. Another method operates a printer by applying a predetermined voltage to an analog input pin of an ADC which identifies the printer (such as, without limitation, the particular make or the particular make and model of the printer). The digital output of the ADC is used to configure a printer-controller ASIC to operate with the identified printer (such as, but not limited to, setting the maintenance cycle timing and/or setting the default printing mode required by the identified printer).
