An inkjet printer 1 has an elastic ink pack 10 that holds ink, and an ink supply mechanism 5 that pressurizes the ink pack 10 and supplies ink to the ink path 4 side. The ink supply mechanism 5 has a pressure pump 15; a remaining ink monitor 52 that watches if the ink in the ink pack 10 has dropped to a specific remaining ink level; a first pressure control unit 56 that drives the pressure pump 15 until the pump pressure reaches a preset first set pressure P1 when the remaining ink has not reached the specific remaining ink level; and a second pressure control unit 57 that drives the pressure pump 15 until the pump pressure reaches a second set pressure P2 that is higher than the first set pressure P1 when the remaining ink has reached the specific remaining ink level.
