Abstract
A printing apparatus including: first nozzles which discharge a dye ink; second nozzles which discharge a pigment ink of the same color as the dye ink; and a controller which controls the discharge of the inks from the first nozzles and the second nozzles, wherein the controller executes a first discharging operation for discharging the dye ink from the first nozzles and then discharging the pigment ink from the second nozzles at predetermined positions on a medium and executes a second discharging operation for discharging the pigment ink from the second nozzles and then discharging the dye ink from the first nozzles at positions different from the predetermined positions on the medium, and wherein a ratio of the dye ink to the pigment ink in the amount of ink discharged in the second discharging operation per unit area is less than that in the first discharging operation per unit area.
