Claim 10:
11. A head controller for a head including a nozzle configured to discharge a liquid by an energy generating element, a first separator and a second separator, the head controller comprising:
a first signal generator configured to generate, based on at least first data representing a first driving waveform and second data representing a second driving waveform different from the first driving waveform, a first time division multiplex signal in which a third portion being a part of the second driving waveform is aligned between a first portion being a part of the first driving waveform and a second portion being other part of the first driving waveform, and the second portion is aligned between the third portion and a fourth portion being other part of the second driving waveform, the first time division multiplex signal being capable of transmitting the first data and the second data via a first signal line being single signal line; and
a second signal generator configured to generate, based on at least third data representing a third driving waveform and fourth data representing a fourth driving waveform different from the third driving waveform, a second time division multiplex signal in which a seventh portion being a part of the fourth driving waveform is aligned between a fifth portion being a part of the third driving waveform and a sixth portion being other part of the third driving waveform, and the sixth portion is aligned between the seventh portion and an eighth portion being other part of the fourth driving waveform, the second time division multiplex signal being capable of transmitting the third data and the fourth data via a second signal line being single signal line, wherein
the first separator is configured to separate a first driving waveform signal representing the first driving waveform or a second driving waveform signal representing the second driving waveform from the first time division multiplex signal generated by the first signal generator;
the second separator is configured to separate a third driving waveform signal representing the third driving waveform or a fourth driving waveform signal representing the fourth driving waveform from the second time division multiplex signal generated by the second signal generator;
the energy generating element is driven by the first driving waveform signal or the second driving waveform signal separated by the first separator, or the energy generating element is driven by the third driving waveform signal or the fourth driving waveform signal separated by the second separator; and
a waveform of the first time division multiplex signal and a waveform of the second time division multiplex signal are different from each other.
