Abstract
A printing device comprises a nozzle configured to eject liquid by an energy generating element, a first selector configured to select, for each particular time period, data indicating a drive waveform based on a voltage value in the particular time period, a signal generator configured to generate a time-division multiplex signal, and a separator configured to separate a drive waveform signal indicating the drive waveform from the time-division multiplex signal generated by the signal generator. The energy generating element is configured to be driven by the drive waveform separated by the separator, and the signal generator is configured to increase an assigned time period, in the particular time period, assigned per the drive waveform selected by the first selector as a number of the drive waveforms selected by the first selector decreases.
