Abstract
A first drive waveform for causing a liquid to be discharged from a first discharge unit and performing printing becomes a first potential during a first period, becomes a fourth potential during a second period, and becomes the first potential during a third period. A second drive waveform for inspecting the first discharge unit becomes a second potential during a fourth period, becomes a third potential during a fifth period, and becomes the second potential during a sixth period, where the third potential is lower than the fourth potential and the first potential.
