Abstract
A liquid discharge apparatus includes a recording head, a drive waveform generating unit, a transmission path, a switching unit, and a switching control unit. The recording head is configured to discharge liquid. The drive waveform generating unit is configured to generate a head drive waveform signal supplied to the recording head. The transmission path includes a plurality of transmission lines forming pairs and is configured to transmit the head drive waveform signal generated by the drive waveform generating unit to the recording head. the switching unit is arranged between the drive waveform generating unit and the transmission path, and is configured to change directions of electric currents in the transmission lines. The switching control unit is configured to control the switching unit in accordance with a change in a load capacity of the recording head.
