Abstract
There is provided a printing apparatus for performing printing on a printing medium with a capability of discriminating the type of printing medium on which the printing is to be executed, whereby various printing conditions can be properly selected and set up. Sensors for measuring the reflectances of a front side face, on which the printing will be performed, and of a back side face of the printing medium are provided and the type of printing medium is discriminated through the use of a difference value of the two reflectances and previously-measured standard values. The printing is executed on the printing medium that was discriminated in this way under proper printing conditions.
