<p> ABSTRACT A head driving control apparatus for driving a pressure generation part in a droplet discharging headoutputs a driving signal including: a first waveform element for contracting the volume of a pressurizing chamber without discharging a droplet; a second waveform element for keeping a contracted state until a meniscus in a nozzle moves toward the pressurizing chamber; a third waveform element for expanding the volume of the pressurizing chamber from the contracted state; a fourth waveform element for keeping an expanded state; and a fifth waveform element for contracting the volume of the pressurizing chamber to discharge a droplet.</p> |
