1. A printing apparatus comprising:
a first digital synthesizer configured to generate a first basic analog synthesis signal by synthesizing n pieces of digital data and converting the synthesized n pieces of digital data to an analog signal, each of the n pieces of digital data indicating a driving waveform used to drive an energy generating element to cause a nozzle to eject liquid, the n being a natural number greater than or equal to 2;
an integrated signal synthesizer configured to generate an integrated analog signal by synthesizing the first basic analog synthesis signal and one or more analog waveform signals indicating one or more driving waveforms, respectively; and
a separator configured to separate one of a driving waveform signal indicated by one of the n pieces of digital data and driving waveform signals indicated by the one or more analog waveform signals from the integrated analog signal generated by the integrated signal synthesizer.
