Abstract
A mobile telecommunications device having a printer module and sensor module in a media feed path is disclosed. A drive means transports a print medium through the media feed path. The sensor module senses data encoded on a surface of the print medium in the media feed path. The data encodes a print media identifier which uniquely identifies the print medium and at least part of the digital signature of the print media identifier. The print media identifier and at least part of the digital signature are determined from the data, and it is determined whether the digital signature is authentic. The printer module prints content on the print medium in the media feed path if the digital signature is authentic.
