Abstract: A print media and a photo printer with improved print quality are provided. The print media includes a printing area, and a mark area formed at one side of the printing area and having first marks formed at regular intervals in a printing direction. The photo printer can measure an actual travel distance of the print media by detecting the marks formed on one side of the print media. Accordingly, the photo printer enables print timing to be exactly synchronized with the feeding of the print media.

Abstract: An image forming apparatus includes a main body, an image forming section disposed in the main body to form an image on paper, and a reciprocation section for enabling the paper to exit and re-enter the main body while the image is formed by the image forming section. A driver section moves paper to the reciprocation section and senses movement of the paper to determine whether a paper reciprocation space is clear of obstacles to reciprocate the paper. Thus, prior to image formation, it is sensed whether both the reciprocation space allowing the paper to exit and re-enter and a loading space allowing the paper on which the image is formed to be loaded are sufficiently clear of obstacles to provide efficient image formation.
