Abstract
A blower is disposed at least at backward side of printing moving direction of the head unit, out of two sides of the head unit. The blower has air nozzles for injecting compressed air perpendicularly to the printing plane, and the bottom of the blower is provided with a curved plane and a parallel plane so that the compressed air injected from the air nozzles may be bent in a direction at right angle by Coanda effect. The curved plane and the parallel plane generate a horizontal air stream parallel to the printing plane, toward a direction departing from the adjacent head unit, at the downside of the blower. The printing device, using the ink jet head, dries the ink on the printing medium by the horizontal air stream injected from the blower while printing on the printing medium.
