摘要

When a printer carries out maintenance by control by a maintenance control portion 52, an ink information obtaining portion 73 calculates the amount of the consumed ink. The calculated ink amount is stored in a storage element attached to an ink cartridge by a storage element managing portion 74. By doing this, the amount of ink not used in actual printing such as the amount of ink used for maintenance can be grasped by reading out the contents of the storage element later.
