A printer includes a conveyance unit, a print head, and a braking member. The conveyance unit includes first and second rollers arranged in a state of being in pressure contact with each other with a conveyance path for conveying a long printing medium interposed therebetween, and applies a conveyance force to the printing medium by rotating the first and second rollers. The print head is disposed upstream of a position where the conveyance unit applies the conveyance force in a forward direction along the conveyance path, and performs printing on the printing medium conveyed in the forward direction through the conveyance path. The braking member is disposed in contact with the second roller, is moved, by a frictional force generated by rotation of the second roller in the forward direction, to a first position where a first braking force is applied to the printing medium, and is moved, by a frictional force generated by reverse rotation of the second roller, to a second position where a second braking force larger than the first braking force is applied to the printing medium.
