<p>The preliminary waveform driving region is made in the period in which the head is accelerated just after the head starts moving for printing until it reaches the printing starting position, and a preliminary waveform generated in the preliminary waveform driving region stirs the ink in the opening of the nozzle of the head to the extent where the ink is not discharged to reduce the viscosity of the ink and the printing is performed in the usual printing region immediately after the head passes the preliminary waveform driving region. Accordingly, this can drive the head for printing before the viscosity of the ink, which is reduced by the preliminary driving motion, is increased to easily discharge the ink from the nozzle when the head performs the printing. <IMAGE></p> |
