Abstract
Three waveform generators are provided in order to generate three kinds of basic waveform signals. The waveform generators generate the basic waveform signals in correspondence with parameter data inputted from a parameter register. A head driver selects one waveform signal from the basic waveform signals based on image information, and outputs a driving pulse of the same waveform to a corresponding driving element.
