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.

A printing-medium type discrimination device applied to a printing apparatus for performing printing on a printing medium, comprising:
- means for acquiring information of both a front side face, on which the printing will be executed, and a back side face of the printing medium;
- and
- means for discriminating the type of the printing medium through the use of the acquired information.
A printing medium that bears information concerning its own type thereon, wherein
- said information is provided at a position that can be read by means for acquiring information of both a front side face, on which printing will be executed, and a back side face of the printing medium.
A printing apparatus for performing printing on a printing medium by using a print head, comprising:
- means for acquiring information of both a front side face, on which the printing will be executed, and a back side face of the printing medium;
- means for discriminating the type of the printing medium through the use of the acquired information;
- and
- means for executing the printing that is suited to the printing medium on which the printing is to be executed according to the discrimination of said discriminating means.
A printing system, comprising:
- a printing apparatus having means for acquiring information of both a front side face, on which printing will be executed, and a back side face of a printing medium, means for discriminating the type of the printing medium through the use of the acquired information, and means for executing the printing that is suited to the printing medium on which the printing is to be executed according to the discrimination of said discriminating means;
- and
- an image data supplying apparatus for supplying image data to be printed to said printing apparatus.
A printing-medium type discrimination method applied to a printing apparatus for performing printing on a printing medium, comprising the steps of:
- acquiring information of both a front side face, on which the printing will be executed, and a back side face of the printing medium;
- and
- discriminating the type of the printing medium through the use of the acquired information.
A printing method for performing printing on a printing medium by using a print head, comprising the steps of:
- acquiring information of both a front side face, on which the printing will be executed, and a back side face of the printing medium;
- discriminating the type of the printing medium through the use of the acquired information;
- and
- executing the printing that is suited to the printing medium on which the printing is to be executed according to the discrimination.
A printing method applied to a printing system comprising an image data supplying apparatus and a printing apparatus, said method comprising the steps of:
- supplying image data to be printed to said printing apparatus from said image data supplying apparatus;
- acquiring information of both a front side face, on which the printing will be executed, and a back side face of a printing medium before printing of said image data;
- discriminating the type of the printing medium through the use of the acquired information;
- and
- executing the printing that is suited to the printing medium on which the printing is to be executed according to the discrimination.
A program for performing a printing-medium type discrimination method applied to a printing apparatus, said method comprising the steps of:
- acquiring information of both a front side face, on which printing will be executed, and a back side face of a printing medium;
- and
- discriminating the type of the printing medium through the use of the acquired information.
A program for performing a printing method for executing printing on a printing medium by using a print head, said method comprising the steps of:
- acquiring information of both a front side face, on which the printing will be executed, and a back side face of the printing medium;
- discriminating the type of the printing medium through the use of the acquired information;
- and
- executing the printing that is suited to the printing medium on which the printing is to be executed according to the discrimination.
A program for performing a printing method applied to a printing system comprising an image data supplying apparatus and a printing apparatus, said method comprising the steps of:
- supplying image data to be printed to said printing apparatus from said image data supplying apparatus;
- acquiring information of both a front side face, on which the printing will be executed, and a back side face of a printing medium before printing of said image data;
- discriminating the type of the printing medium through the use of the acquired information;
- and
- executing the printing that is suited to the printing medium on which the printing is to be executed according to the discrimination.
