ABSTRACT:
A head drive waveform generation device and a head drive waveform generation method that do not require large-capacity memory during mounting on a printer are disclosed. The head drive waveform generation device generates and outputs, based on head drive waveform data consisting of a plurality of waveform data elements that comprise inclination values serving as information for specifying signal changes per unit of time, and interval widths serving as information for specifying time intervals during which the inclination values are used, head drive waveforms whose magnitude varies over time in accordance with the inclination values within the waveform data elements, during the time intervals specified by the interval widths within the waveform data elements.
