Liquid jet apparatus, printing apparatus, and method of adjusting phase of drive pulse

A printing apparatus comprising:

• a plurality of nozzles provided to a liquid jet head;
• a plurality of actuators provided so as to correspond to each of the nozzles;
• and
• drive unit that applies a drive pulse to each of the plurality of actuators,
• wherein the drive unit includes:
• correction value storing unit that corrects a drive pulse application timing correction value corresponding to the number of actuators to be driven at the same time in order to compensate for an increased electrical interference generated by multiple actuators being driven at the same time, and
• drive pulse application timing correction unit that corrects the drive pulse application timing using the drive pulse application timing correction value corresponding to the number of actuators to be driven at the same time, which is stored in the correction value storing unit.
