<p>The ink jet apparatus of an ink jet printer includes an ink jet head (600). The head has an ink channel (613), a nozzle (618), and an actuator for ejecting ink from the channel through the nozzle. A drive unit (211,212,213) can drive the actuator. A control unit (221,222,223) generates print data, on which the control unit is based to control the drive unit. A stop pulse data generator (44,61) carries out a logical operation of the print data for each print cycle Tm and the print data for the next print cycle Tm+1 to generate a predetermined stop pulse data if the former data is a data for execution of printing and if the latter data is a data for no execution of printing. After printing is executed in accordance with the print data for the cycle Tm, the drive unit is based on the stop pulse data to drive the actuator so as to damp the pressure wave vibration generated in the channel. <IMAGE></p> |
