A printing device (10) includes: an inkjet head (30) ejecting ink to paper (20); a tube (32) supplying ink to the inkjet head (30); an ink tank (36) connected to the tube (32) and storing the ink supplied by the tube (32); a housing (38) housing the ink tank (36); a detection device detecting the volume of the ink tank (36); a regulator adjusting the negative pressure of the space between the ink tank (36) and the housing (38); a pump connected to the regulator for generating a negative pressure having a constant value used by the regulator for adjusting the negative pressure of the space; and a CPU (70) controlling the regulator so that the negative pressure of the space between the ink tank (36) and the housing (38) corresponds to the volume detected by the detection device. Accordingly, the small-sized device can be used to reduce waste of the stored fluid and shorten the takt time.
