Printing apparatus and ink leakage detection method in printing apparatus
A printing apparatus includes: a printing unit configured to eject ink supplied from a storage unit to perform a printing operation; a detection unit configured to detect ink stored in the storage unit; and an acquisition unit configured to acquire a consumption amount of ink consumed in the printing operation from the storage unit. The printing apparatus includes: a calculation unit configured to calculate a decrease amount that is a difference between the ink amount in the storage unit detected by the detection unit prior to the printing operation and the ink amount in the storage unit detected by the detection unit after the printing operation; and a determination unit configured to determine an ink leakage in a case where a difference between the decrease amount calculated by the calculation unit and the consumption amount acquired by the acquisition unit is larger than a threshold value.
