PROBLEM TO BE SOLVED: To provide a printer performing printing by feeding out a print medium from a sheet roll wound with a long print medium in which the print medium can be rewound on the sheet roll without bending a roll sheet on a carrying passage while reducing the cost and size. SOLUTION: Carry rollers 6a and 6b for carrying a print medium M fed out from a sheet roll R and a roll rotary shaft 8 for rewinding the print medium M by rotating the sheet roll R are rotated using one drive motor 7 as a drive source. Rewinding amount of the print medium M through rotation of the roll rotary shaft 8 per unit rotational frequency of the drive motor 7 is set larger than the carrying amount of the print medium M by the carrying roller 6a and 6b even when the outside diameter of the sheet roll R is minimum.
