As a replacement cartridge is moved closer to a wireless communication section provided on the housing of a printer, information stored in a non-volatile memory of the replacement cartridge is acquired by the wireless communication section. A CPU of the printer compares the amount of ink remaining in the replacement cartridge, obtained from the acquired information, with the amount of an ink remaining in a cartridge on a carriage which retains an ink of the same color as the color of the ink in the replacement cartridge. In the case where the ink remaining amount in the replacement cartridge is larger, the CPU decides that the cartridge should be replaced and moves the carriage in such a way that the target cartridge for replacement is positioned directly under an opening portion in the housing. This makes the cartridge replacement task easier.
