Abstract
A printing apparatus including a first nozzle that ejects dye ink; a second nozzle that ejects pigment ink of a color that is the same as the dye ink; and a controller that controls ejection of ink from the first nozzle and the second nozzle. The controller performs a first ejection operation, in which the pigment ink is ejected from the second nozzle after the dye ink is ejected from the first nozzle, for a predetermined position on a medium and performs a second ejection operation, in which the dye ink is ejected from the first nozzle after the pigment ink is ejected from the second nozzle, for a second position on the medium. An amount of the pigment ink per unit area that is ejected in the second ejection operation is made smaller than an amount of the pigment ink per the unit area in the first ejection operation.
