Printing device

A printing device, comprising:

• a nozzle configured to eject liquid by an energy generating element;
• a signal generator configured to generate a time-division multiplexed signal where first data indicating a first drive waveform and second data indicating a second drive waveform are multiplexed, the first data and the second data being transmittable by the time-division multiplexed signal through a single signal line, the time-division multiplexed signal being generated based on at least the first data and the second data, the time-division multiplexed signal including a first part of the first drive waveform, a second part of the first drive waveform, a third part of the second drive waveform and a fourth part of the second drive waveform, the third part being arranged between the first part and the second part, the second part being arranged between the third part and the fourth part;
• and
• a separator configured to separate one of a first drive waveform signal indicating the first drive waveform and a second drive waveform signal indicating the second drive waveform from the time-division multiplexed signal, and
• wherein the energy generating element is configured to be driven by one of the first drive waveform signal and the second drive waveform signal, the first drive waveform signal being a signal separated by the separator by a first pulse signal having a period shorter than a period of the first part and a second pulse signal having a period shorter than a period of the second part, the second drive waveform signal being a signal separated by the separator by a third pulse signal having a period shorter than a period of the third part and a fourth pulse signal having a period shorter than a period of the fourth part,
• wherein each of the first data and the second data includes a plurality of quantized data values,
• wherein the signal generator includes:
• a controller;
• a digital-to-analog converter configured to convert the plurality of quantized data values to an analog signal;
• an amplifier configured to amplify the analog signal;
• and
• a memory configured to store the first data and the second data,
• wherein the controller is configured to generate the time-division multiplexed signal by reading the plurality of quantized data values of the first data and the second data from the memory and transmitting the plurality of quantized data values in a time series,
• wherein the digital-to-analog converter is further configured to output the analog signal to the amplifier,
• wherein the amplifier is further configured to output the amplified analog signal to the separator, and
• wherein the separator is configured to separate one of the first drive waveform signal and the second drive waveform signal from the amplified analog signal.
