Abstract
A liquid ejecting apparatus is configured to drive a drive element that is driven in accordance with a drive signal for ejecting a plurality of liquid droplets such that the liquid droplets merge together before landing onto a medium. The drive signal includes a plurality of drive waveforms and a first connection waveform that is continuous from a second-to-last drive waveform and continuous to a last drive waveform and along which a potential of the drive signal is kept at a reference level. Pressure changes caused by the contraction waveform of the last drive waveform in a liquid present inside the pressure compartment are larger than pressure changes caused by the contraction waveform of the second-to-last drive waveform in the liquid present inside the pressure compartment. A period of the first connection waveform is 0.8 or more times as long as a natural vibration cycle of the ejecting portion.
