Abstract
A liquid ejecting apparatus comprises a liquid ejecting head having a drive element that is driven in accordance with a drive signal to eject liquid droplets from a nozzle. The drive signal comprises a first drive waveform including a first contraction waveform to eject a first liquid droplet and a second drive waveform including a second contraction waveform to eject a second liquid droplet which merges with the first liquid droplet before the first liquid droplet lands onto a medium. The first contraction waveform includes a first segment waveform along which the potential changes, a second segment waveform along which the potential is kept, and a third segment waveform along which the potential changes. The second contraction waveform includes a fourth segment waveform along which the potential changes, a fifth segment waveform along which the potential is kept, and a sixth segment waveform along which the potential changes.
