A fixing device 26 is provided on the left side of the photosensitive drum 27, and an exit chute 24 is attached to the exit of the paper passage 25. The printing apparatus receives the detection output of the paper sensor and controls the printing start timing and the like. On the other hand, normal paper without holes as printing paper,
There is a printing paper having binding holes formed on the edges.

[0004]

However, the conventional printing apparatus has the following problems. That is, the binding holes of the sheet differ depending on the sheet used, and it is difficult to attach the sheet sensor so as to avoid all the binding holes. Therefore, depending on the type of paper, the binding hole may be located at a position just opposite to the paper sensor, and the paper sensor may erroneously detect that it is the end of the paper, thus preventing normal printing operation. In such a case, if the paper is inserted in the opposite direction, the binding hole can be removed from the paper sensor, so that the paper sensor can be operated normally and printing can be performed. In many cases, the directionality of printing is necessary, and there is a problem that printing in the opposite direction is useless.
