ABSTRACT:
Method of feeding a sheet of paper in a small-sized paper having small transport rollers mounted downstream of the print head. The feeding of the sheet is stopped temporarily when the sheet arrives at each of a number of positions located before the discharge rollers during a line feed operation. Under this interrupted condition, the print head is reciprocated once idly in a direction perpendicular to the direction in which the sheet is fed. Therefore, even if the front end portion of the sheet curls to a great extent, the curl is reduced by the idle movement of the head immediately before the front end of the sheet arrives between the discharge rollers. This ensures that the sheet is fed between the discharge rollers even if the diameter of the rollers is small.
