Abstract: A paper feeder of a label printer makes printing successively on a continuous printing paper on which a multiplicity of label papers are affixed. The paper feeder includes a control device for moving back the continuous printing paper by a length obtained by adding a fixed length capable of continuously making the next printing subsequently to a final printing position of the printing paper upon resumption of the printing operation when the movement of the printing paper is stopped by completion of the printing operation to an adjustment length for settling a printing position and makes printing successively from a fixed position of the label paper upon resumption after the printing operation is stopped.
