Abstract

A device for driving a recording head comprises select data input elements, a waveform signal selector, and a drive signal supplier. To the select data input elements, select data sets corresponding to recording elements included in the recording head are inputted in a serial manner. Each one of the select data sets indicates which one among waveform signals is to be employed for a corresponding recording element in a single printing cycle. The waveform signal selector selects, for each of the recording elements, one among the waveform signals on the basis of a corresponding one among the select data sets inputted to the select data input. The drive signal supplier supplies, based on the selected waveform signal, a drive signal to each of the recording elements. The number of the select data input elements is greater than the number of bits included in each of the select data sets. The number of signal lines through which the select data sets are inputted to the select data input elements in a serial manner is the same as the number of the select data input elements.
