A printing apparatus having an adhesive applying function is provided with a transporting mechanism for transporting an elongated print member, a transferring mechanism for transporting a transferring member having adhesive, contained in a cartridge installed on the apparatus, and for selectively bringing the transferring member into contact with the print member transported by the transporting mechanism, thereby transferring the adhesive of the transferring member onto the surface of the print member which no data is to be printed on, a controlling unit for controlling whether the transferring mechanism transfers the adhesive of the transferring member onto the surface of the print member which no data is to be printed on, and a printing mechanism provided on the downstream side of the transferring mechanism, for processing print data including rotation of the data in unit of 90 degrees, and for printing the data on the surface of the print member.
