Abstract
A standard drive waveform contains, in one ejection cycle: a first ejection waveform group including at least one ejection waveform causing liquid to be ejected from a nozzle to form one dot of a maximum size; a first non-ejection waveform arranged after the first ejection waveform group; a second ejection waveform group including at least one ejection waveform causing the liquid to be ejected from the nozzle to form a dot of a minimum size; and a second non-ejection waveform arranged after the second ejection waveform group. At least one of the ejection waveforms is selected from one of the first and second ejection waveform groups in accordance with ejection data. When the selected ejection waveform belongs to the first ejection waveform group, the first non-ejection waveform is further selected. When the selected ejection waveform belongs to the second ejection waveform group, the second non-ejection waveform is further selected.
