A microprocessor based dispenser control system for controlling the dispensing process in a liquid pump and storing information on the type and number of times the liquid has been dispensed is disclosed. The system includes a dispensing pump and a control console for controlling the pump. The console is interfaced to a cash register, point-of-sales system, or printer for down-loading information to these. In a preferred embodiment, the dispensing pump is a squeeze type pump driven by a stepper motor. The microprocessor uses a pulse drive source to control the stepper motor.
