Abstract

The present invention relates to a device having a first determining unit configured to determine whether version information included in a two-dimensional code included in an input image is version information that is supported by the device and a second determining unit configured to determine to prohibit printing of the input image when the included version information is determined to be version information that is not supported by the device or to determine whether to permit or prohibit printing of the input image based on information other than the version information included in the two-dimensional code when the included version information is determined to be version information that is supported by the device. With this arrangement, it is possible to execute processing in accordance with version information included in a two-dimensional code.

First claim

What is claimed is:

1. A printing apparatus comprising:
an input unit configured to input an image;
a detecting unit configured to detect a two-dimensional code in the input image;
a determining unit configured to determine whether a version which is included in the detected two-dimensional code is a compliant version of the printing apparatus;
a replacing unit configured to replace the detected two-dimensional code with a new two-dimensional code in the input image; and
a…
