The present disclosure prevents a visible pattern corresponding to the pattern of a mask from being noticeable and enables more appropriate printing. A printing apparatus 10 performing printing by an inkjet scheme includes: an inkjet head 102; and a controller 20, configured to control the operation of a main scan driver 16 and a sub scan driver 18 to perform a main scanning operation multiple times on each position on a medium 50. In the main scanning operation, for at least part of ejection positions serving as ejection targets of ink droplets in the main scanning operation, the controller 20 causes the inkjet head 102 to eject an ink droplet in accordance with a mask for selecting part of the at least part of ejection positions. In the main scanning operation at one time, the controller 20 causes the inkjet head 102 to eject an ink droplet in accordance with a preset first mask. In the main scanning operation at another time different from the one time, the controller 20 causes the inkjet head 102 to eject an ink droplet in accordance with a second mask for selecting an ejection position in a pattern different from the first mask.
