Abstract

A low-price printing apparatus with excellent operability, capable of accurate residual-ink amount management, and an ink-consumption amount management method for the apparatus. In the printing apparatus, when printing is performed by discharging ink supplied from a replaceable ink tank from a printhead onto a printing medium based on print data received from a host, ink-consumption amount information is stored into a storage medium, then ink consumption is counted, and the ink-consumption amount information stored in the storage medium is updated based on the counted ink consumption amount. On the other hand, occurrence of replacement of ink tank is determined, then the ink-consumption amount information upon determination is stored as first consumption-amount information into the storage medium, then the result of determination is notified to the host, then as a result of notification, the ink amount information of ink contained in an ink tank newly set by replacement of the ink tank is received, and the obtained ink-consumption amount information is updated based on the ink-consumption amount information updated upon reception, the first consumption-amount information stored in the storage medium, and the received ink amount information.
