According to one embodiment, a printer includes a housing that has an outlet, a drawer unit, first, second and third print medium support units and a printing unit. The drawer unit slides in the outlet between an open position and a closed position. The first supporting unit is disposed in the drawer unit and supports a roll of printable media when the drawer unit is in the open position so that an outer surface of the roll of printable media does not extend above the height of the outlet. The second supporting unit is disposed in the housing and rotatably supports the roll of printable media when the drawer unit is in the closed position so that a portion of the outer surface of the roll of printable media extends above the height of the outlet. The printing unit prints on printable media fed from the roll of printable media.

A rolled paper printing apparatus includes a roller, a cutter capable of cutting the rolled paper and including a first blade and a second blade, a first blade-side guide capable of guiding, from the side of the first blade, the paper transported, and a paper guide including a first guide and a second guide. The paper guide includes a first arm on which the first guide is mounted rotatably about a first shaft, a second arm on which the second guide is mounted rotatably about a second shaft, and an arm shaft that rotatably supports the first arm and the second arm. The first guide and the second guide are pushed by the first blade moving in the first direction, and move in the first direction while rotating from a first position at which the paper can be guided and reach a second position.
