To calculate a residual quantity of ink in an ink cartridge and to announce an ink suction operation right after the loading of the ink cartridge without causing leaking of the ink from a recording head and generating of the ink-out during the printing.
This recorder composes an ink quantity calculating means 32 that adds a quantity of ink that is to be discharged by a suction operation as a consumption quantity of ink before the suction operation and a suction controlling means 29 that executes the suction operation after the adding operation. The residual ink quantity is calculated such that the large quantity of the ink which will be consumed by the suction operation is estimated to be consumed beforehand. As a result, it is possible to add the quantity to a consumption quantity memory means 33 even when a power switch SW is turned off before the suction operation is completed. The residual quantity is fully indicated on an indication means 38 at a stage when the ink suction operation is completed after an ink cartridge is loaded.
