Abstract
To suppress nozzle clogging without reducing printing speed, a printing device of the invention includes a plurality of nozzles for discharging ink while moving in a movement direction; a conveying unit for conveying a medium in a conveying direction; and a controller for repeating a dot-forming action for discharging ink from the nozzles moving in the movement direction and forming dots on the medium, and a conveying action for conveying the medium in the conveying direction. The controller places an additional image in a different position in the movement direction from an area where a main image to be printed is formed, discharges ink from all of the nozzles in each of the dot-forming actions, and prints the additional image on the medium.
