More Information
Summary:A liquid discharge device includes: a piezoelectric element to which a drive voltage is applied; a nozzle from which a liquid is to be discharged in accordance with a change of the drive voltage; and circuitry configured to: generate: a first drive waveform including first multiple pulses switchable at first switch timings; and a second drive waveform including second multiple pulses different from the first multiple pulses switchable at second switch timings, at least one the first switch timings of the first multiple pulses of the first drive waveform and at least one of the second switch timings of the second multiple pulses of the second drive waveform are the same; select first selected pulses from the first multiple pulses in the first drive waveform; and select second selected pulses from the second multiple pulses in the second drive waveform.
