Abstract
An apparatus for driving an ink-jet recording head includes a piezoelectric device, a drive waveform generation circuit, a waveform extraction circuit. The drive waveform generation circuit generates a drive waveform in which n basic waveforms are connected in series, each of the n basic waveforms having a single period, where n is an integer equal to or greater than 2. The waveform extraction circuit which extracts m (m is an integer, and 0≦m≦n) of the n basic waveforms as a print drive waveform based on an externally supplied print data, and applies the print drive waveform to the piezoelectric device. Thereby, an ink is discharged from a nozzle based on a distortion of the piezoelectric device.
