A first printing unit and a second printing unit are supplied with ink from a first sub-tank and a second sub-tank, respectively. The first sub-tank and the second sub-tank are supplied with the ink from a first branch pipe and a second branch pipe, respectively. The first branch pipe is provided with a first valve, and the second branch pipe is provided with a second valve. A central control unit determines which one of the first sub-tank and the second sub-tank is to be preferentially supplied with ink based on at least one of the amount of remaining ink in each of the first sub-tank and the second sub-tank, and an estimated amount of consumption of ink in each of the first printing unit and the second printing unit, and controls the first valve and the second valve based on a result of the determination.
