An image forming apparatus includes a housing, a feeding tray capable of being inserted into and pulled out from the housing, a feed roller, and one or more detection units. The feeding tray includes a first accommodation part in which a roll body having a configuration where a sheet-shaped medium is rolled in a roll shape is accommodated and a second accommodation part in which a plurality of sheet-shaped media are accommodated in a state of being stacked. The feed roller feeds a sheet-shaped medium from the feeding tray toward a conveying path. The image forming unit forms an image on a sheet-shaped medium provided in the conveying path. The one or more detection units detect whether a sheet-shaped medium is arranged in a predetermined position in the feeding tray.

A thermal-transfer printing apparatus includes a roll-paper-supplying unit that rotates an image-receiving paper roll and unwinds and winds a roll type of first image-receiving paper, and a print unit that includes a thermal head for heating a thermal transfer sheet and that forms an image by transferring a color material from the thermal transfer sheet to the first image-receiving paper. With the image-receiving paper roll removed, a reverse unit that reverses a sheet type of second image-receiving paper is mountable in a region in which the image-receiving paper roll used to be contained. The print unit forms the image on the first image-receiving paper in a first printing mode in which the image-receiving paper roll is contained in the region, and the print unit forms an image on both surfaces of the second image-receiving paper in a second printing mode in which the reverse unit is mounted on the region.

A control device includes a processor configured to: acquire information on a direction in which continuous paper is wound up, specify a viewable surface, which is a surface of the continuous paper viewable from a user in a state where the continuous paper has been wound up, on a basis of the direction in which the continuous paper is wound up, and control a printer to print print information, which is information on a job printed on the continuous paper, on the viewable surface.

A medium cassette of the present disclosure is a medium cassette configured to be inserted and removed with respect to an apparatus main body and capable of selectively accommodating any recording medium of a roll medium having a continuous medium which is wound in a roll shape and a single sheet medium.
