An inkjet printer prevents the paper from lifting away from the platen when the suction action of the platen is stopped, and thereby prevents paper jams and other printing problems. The printer 1 conveys the printing paper 12a while holding the paper 12a to the surface of the platen 19 by a suction mechanism 50. After the automatic paper cutting operation is completed, the leading end part 12b of the printing paper 12a is retracted from the cutting position B to the printing start position A on the platen 19, and the printer 1 waits for the next print job with the printing paper 12a held against the platen 19. When a power conservation mode or power off mode is entered, the control unit 61 of the printer 1 advances the leading end part 12b of the printing paper 12a from the printing start position A to the cutting position B so that the paper is held by the downstream-side paper feed roller 34 and pressure roller 35, and then stops the power supply to the suction mechanism 50 of the platen 19. The printing paper 12a can thus be prevented from rising away from the platen 19 while the vacuum action of the suction mechanism 50 is stopped.
