A printing apparatus of the invention prints images by ejecting ink from nozzles onto a printing medium. The printing apparatus includes a first sub-tank which is set at the relatively high position, a second sub-tank which is set at the relatively low position (position set relative to one another), and a main tank which holds ink to be supplied to the first and second sub-tanks. When ink is supplied to the first sub-tank, the ink is supplied from the main tank with relatively high pressure. When ink is supplied to the second sub-tank, the ink is supplied from the main tank with relatively low pressure. The first and second pressures are pressures such that ink is not ejected from the opening of the nozzles when ink is supplied from the main tank to the sub-tanks in the situation that ink can be supplied from the sub-tank to the opening of the nozzles. With this printing apparatus, ink can be supplied efficiently from the main tank to the sub-tanks arranged at the different heights.
