A serial signal for generating a plurality of recording waveform signals is transmitted serially from a signal transmission circuit to a head river. A serial-parallel converting circuit parallely converts the serial signal and generates a plurality of kinds of the recording waveform signals. A selector in the head driver selects a predetermined recording waveform signal from the plurality of kinds of the recording waveform signals based on a selection signal corresponding to each of actuators. The drive pulse of the selected recording waveform signal is outputted to a recording head and carries out dot recording.
