摘要：
There is provided a technique with which an abnormal discharge state in a discharge component can be determined on the basis of residual vibration. A printer includes a discharge component that discharges ink, a detector that detects residual vibration in the discharge component, and a tester that tests the discharge component on the basis of the change in the period of the residual vibration.
