Abstract
An embodiment of this invention is directed to a printing apparatus capable of providing an output result without a printing density difference between two surfaces in two-sided printing. In the printing apparatus, one subtank is provided for each type of ink. The nozzles of printheads that receive inks supplied from the subtank and are used for printing of the front surface of a printing sheet and printing of the back surface, respectively, are aligned to almost the same level in the vertical direction, thereby making the water head pressures match.
