A printing device calculates a status value of a surface of a print medium to determine the appropriateness of the print medium for printing. Light fluxes are inputted to the surface of the print medium at an incidence angle. An image pickup unit picks up reflection light fluxes and a measurement-target surface status value calculating unit calculates a status value relating to the appropriateness of the print medium for printing based on the picked up luminance information.
