Printing apparatus

A printing apparatus comprising:

• a transport unit for a printing medium;
• a head configured to discharge ultraviolet-curable ink onto the printing medium;
• an ultraviolet light irradiation unit disposed downstream of the head in a transport direction of the printing medium;
• a suction unit provided with a suction port for suction mist of the ink, the suction port being provided between the head and the ultraviolet light irradiation unit in the transport direction;
• and
• a gap reducing portion disposed in a gap between the head and the suction unit in the transport direction and configured to at least partially close the gap by a first region being in contact with the suction unit and a second region, located upstream of the first region in the transport direction, being in contact with the head, wherein
• in response to the suction unit suctioning the mist while the head discharges the ink onto the printing medium to be transported, air flow traveling in a direction opposite to the transport direction is generated in an opposing region where the ultraviolet light irradiation unit and the printing medium oppose each other, and
• wherein the gap reducing portion has a length, in an intersecting direction that intersects with the transport direction, greater than or equal to a length of the head in the intersecting direction.
