A feeding device that feeds a rolled paper to a printing apparatus is provided with a feeding mechanism, a tension measuring mechanism, and an outlet side guide roller. The feeding mechanism feeds a predetermined amount of the rolled paper in a forward direction so that slack is provided downstream of the outlet side guide roller. Thereafter, positioning is executed while recovering the rolled paper by feeding it in the opposite direction. The feeding mechanism further includes an inlet feeding mechanism and an outlet feeding mechanism. The inlet feeding mechanism performs a backward feeding of a small amount of the rolled paper, and the outlet feeding mechanism performs a forward feeding of a small amount of the rolled paper, in order to increase tension by pulling the rolled paper from both sides. With the feeding mechanism stopped, the tension measuring mechanism measures the tension, and repeats the process for increasing tension until it is not less than a predetermined value. This permits adequate adjustment of the initial state of a long recording medium when loading it, and prevents the recording medium from being consumed in vain due to a preliminary feeding and breakage.
