PURPOSE:To enable a printed paper to be discharged at high speed, by providing a paper guide for readjusting a slip form paper to a specified part of a paper-feeding passage, a shape sensor for detecting the paper, and a controlling part for rotating a feeding motor at high speed. CONSTITUTION:A paper guide 21 is provided on a base plate 2 on the user's side of a supplying port 1, whereby a feeding passage for a slip form paper 22 is readjusted as a specific part of a paper-feeding passage. A paper feed sensor 3 and shape sensor 15b are provided as a part through which the slip form paper 22 is not passed but at least a part of a continuous form paper is continuously passed. When the sensor 15b generates a detection output, it is decided that the continuous form paper is being used, whereas when such as output is not generated, it is decided that the slip form paper 22 is being used. A circuit for decision and control comprises a main controlling part (MCT) 31, which comprises a microprocessor (CPU) and memories or the like, and a small-scale sub-controlling part (SCT) 32. The SCT 32 drives a feeding motor (LFM) 4 consisting of a stepping motor through a driving circuit (DRV) 33. Accordingly, when the sensor 15b does not generate the detection output and it is judged that the slip form paper is being used in a non-printing state after completion of printing, the paper is discharged at high speed.
