Abstract
A liquid ejecting apparatus is configured to eject liquid in response to a drive signal. The drive signal includes a first ejection pulse, a plurality of second ejection pulses, and a third ejection pulse. An ejection component of the first ejection pulse changes from a first potential to a reference potential and is temporally continuous with an interpulse component. Ejection components of the second and third ejection pulses change from the first potential to a second potential. The second ejection pulses include first vibration suppression components that change from the second potential to the reference potential after the ejection components. The third ejection pulse includes a second vibration suppression component that changes from the second potential to a third potential. The reference potential is a potential between the first potential and the second potential and between the second potential and the third potential.
