Abstract
Ejection of ink is prohibited when a count value of an amount of ink supplied from an ink tank to an ejection head reaches a value limit. An image is displayed to prompt an operator of the printing apparatus to confirm the amount of ink in the ink tank. When the ink remains, the count value of the amount of ink is returned only by a given amount by the selection of the operator. Thus, since the ink in the ink tank is sufficiently consumed and then the ink can be supplemented, all of the ink in an ink bottle can be supplemented. As a consequence, it is possible to prevent the ink remaining in the ink bottle from deteriorating and prevent the remaining ink from being supplemented.
