A printing apparatus acquires image characteristic information about the image characteristics of input image information. The printer apparatus includes a first printhead having ink orifices which are arranged in the printing medium convey direction and correspond to the types of inks used for printing, and a second printhead having ink orifices which are laid out symmetrically to the ink orifices of the first printhead. A multipath/double-head data generator distributes print dots based on the input image information to first and second print dots on the basis of the image characteristic information. A first printhead controller controls multipath printing of the first printhead in accordance with the first print dots. A second printhead controller controls multipath printing of the second printhead in accordance with the second print dots.
