Abstract
An ink jet printer has an ink jet head comprising a nozzle that discharges an ink droplet toward a print medium, and an actuator that makes the nozzle discharge the ink droplet when a pulse signal is applied to the actuator. An applying device can apply at least two kinds of pulse signals to the actuator. The pulse width of each kind of pulse signal mutually differs. A first storage stores at least two kinds of base pulse widths. Each kind of base pulse width mutually differs and corresponds with a different kind of pulse signal. An inputting device inputs a predetermined value which is stored in the second storage. The applying device determines a pulse width of each kind of pulse signal by multiplying the corresponding base pulse width stored in the first storage by the predetermined value stored in the second storage.
