When the user operates a paper feed button 9c while the access cover 11 is open (steps ST1, ST2), the printer 1 moves the printhead 12 from the printhead-down position 12D to the printhead-up position 12U, and moves the second paper feed roller pair 31 from the nip state to the nip-release state (step ST3). When the access cover 11 is then closed, the printer 1 returns the second conveyance roller pair 31 to the nip state, and returns the printhead 12 to the printhead-down position 12D (steps ST4, ST5). The operation for changing the second conveyance roller pair 31 between the nip state and the nip-release state is therefore intuitive, easily understood, and simple for the user.
