An ink jet printer comprising a print head (10), having a plurality of pressure generating elements (17) each associated with a nozzle from which an ink droplet is ejected; a print controller (1), for driving the print head to control an ink ejecting operation thereof; drive signal generating means (8), for generating a drive signal which includes a plurality of drive pulses during every one print period, each of the drive pulses being divided into a plurality of waveform elements; print data generating means, for generating print data which includes a plurality of pulse selection signals each associated with one of the waveform elements; and switching means for selectively inputs to each of the pressure generating elements, at least one of the drive pulses and a new drive pulse which is not originally found in the drive signal and obtained by combining a plurality of waveform elements selected by the print data at the same pulse potential. <IMAGE> |
