ABSTRACT:
A printer comprises a cylindrical platen for supporting and feeding a printing sheet, a pinch roller in resilient contact with the platen to cooperate therewith to feed the cut sheet, and an inclined sheet guide on which a cut sheet is loaded. A leading edge of the cut sheet is inserted into a space between the platen and the pinch roller so that the cut sheet is ready to be compulsorily fed by the platen. When or after a cut sheet is loaded on the sheet guide, the platen is rotated in the reverse direction by a predetermined amount of rotation and then rotated in the forward direction to set the cut sheet at a given print start position. During the reverse rotation of the platen, the leading edge of the cut sheet is pushed up so that the posture of the cut sheet is corrected.
