A printing device comprising:
- a transporter that transports a printing medium;
- a head that ejects ink onto the printing medium and forms an image;
- an inspector that periodically inspects whether or not a dot of the image is omitted;
- and
- a controller that controls the transporter, the head, and the inspector,
- wherein when the inspection of whether or not a dot is omitted is executed, the controller prints, on the printing medium adjacent to the printed image, inspection result information that indicates whether or not the dot is omitted,
- wherein the controller executes the inspection after executing a process of interrupting the transportation of the printing medium and a process of retracting the head positioned above the printing medium from a position above the printing medium,
- wherein if a result of the inspection indicates that a dot is omitted, the controller controls the head retracted and executes a flushing operation, and
- wherein after the flushing operation, the controller returns the head to the position above the printing medium and prints the inspection result information on the printing medium.
