Abstract
There is provided a printing apparatus including: a nozzle configured to discharge a liquid by an energy generating element; a selector configured to select, based on a print job, a driving waveform corresponding to a printing method indicated by the print job, from a plurality of driving waveforms different from each other; a signal generator configured to generate a time division multiplex signal, based on data indicating the driving waveform selected by the selector; and a separator configured to separate a driving waveform signal indicating the driving waveform selected by the selector from the time division multiplex signal generated by the signal generator. The energy generating element is configured to be driven by the driving waveform signal separated by the separator.
Claims14
A printing apparatus comprising:
- a nozzle configured to discharge a liquid by an energy generating element;
- a selector configured to select, based on a print job, at least two driving waveforms corresponding to a printing method indicated by the print job, from a plurality of driving waveforms different from each other, the at least two driving waveforms including a first driving waveform and a second driving waveform;
- a signal generator configured to generate a time division multiplex signal based on data indicating the at least two driving waveforms selected by the selector;
- and
- a separator configured to separate a first driving waveform signal indicating the first driving waveform or a second driving waveform signal indicating the second driving waveform from the time division multiplex signal generated by the signal generator,
- wherein the energy generating element is configured to be driven by the first driving waveform signal or the second driving waveform signal separated by the separator;
- and
- in the time division multiplex signal, 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 another part of the first driving waveform, and the second portion is aligned between the third portion and a fourth portion being another part of the second driving waveform.
A printing apparatus comprising:
- a nozzle configured to discharge a liquid by an energy generating element;
- a signal generator configured to generate a time division multiplex signal, transmittable via a single signal line, based on a plurality of pieces of data each indicating one of a plurality of driving waveforms different from each other;
- and
- a separator configured to separate a driving waveform signal indicating the one of the plurality of driving waveforms from the time division multiplex signal generated by the signal generator;
- wherein both a first period of time and a second period of time are included in a same one cycle of the time division multiplex signal,
- wherein the second period of time is different from the first period of time,
- wherein a number of the data to be used by the signal generator so as to generate the time division multiplex signal during the first period of time is smaller than a number of the data to be used by the signal generator so as to generate the time division multiplex signal during the second period of time, and
- wherein the energy generating element is configured to be driven by the driving waveform signal separated by the separator.
