Systems and methods selectively remove flush drops from a plurality of ink drops ejected by a print engine when printing data for a print job. An input circuit receives a sensor signal that indicates an alarm condition, the sensor signal originating from a sensor that is remote from the alarm monitor. The selected image identifies an appropriate output driver supply voltage, and any auxiliary voltages are controlled as functions of the output driver supply voltage to limit voltage inconsistencies. Further, the terminals may alternate between being Slaves and being the Master to equalize battery consumption of the wireless terminals.
