A printer avoids scratching or damaging the platen and print defects caused by adhesive. The printer 1 prints to thermal paper S that has an adhesive area 150 formed on one side with the edges of the paper adhesive-free, and color layers formed on the other side of the paper. The thermal paper S is wound sequentially into a roll so that the other side is on the outside without applying a liner protecting the adhesive area 150 on the one side. The printer 1 has a platen 18, a heating element unit 43, and a guide incline 45. The platen 18 is disposed to a main cover, rotates in the thermal paper S transportation direction, and applies pressure to the thermal paper S from the one side. The heating element unit 43 selectively heats the other side of the paper. The guide incline 45 guides the thermal paper S in a prescribed direction without contacting the area on the back of the adhesive area 150 on the other side of the thermal paper S after the thermal paper S passes the heating element unit 43, and guides the platen 18 to a prescribed position so that the platen 18 does not contact the heating element unit 43 when the main cover is closed.
