Description

Printing device Technical Field The present invention relates to a printing apparatus. Background Conventionally, as disclosed in patent document 1, a printing apparatus is known that includes a platen roller that feeds recording paper, a cutter provided between the platen roller and a discharge port, and a guide member provided between the platen roller and the cutter. The platen roller is capable of feeding the recording paper in a first direction toward the discharge port and a second direction opposite to the first direction. The cutter cuts the recording paper so as to form a cutting portion and a remaining portion on the recording paper. The guide member suppresses entry of the leading end of the recording paper between the platen roller and the cutter. After the recording paper is cut by the cutter, when the recording paper is fed in the second direction in a state in which the first recording paper portion, which is a portion located in the first direction with respect to the cutting portion and the remaining portion, and the portion located in the second direction with respect to the cutting portion and the remaining portion are connected together, there is a possibility that the first recording paper portion gets caught on a guide member provided between the cutter and the platen roller.
