Method of printing and retrieving information using a mobile telecommunications device

A method of printing first information on a print medium using a mobile telecommunications device and retrieving further information, said method comprising the steps of:

• providing the print medium having a linear data track extending along a side of the print medium and a two-dimensional coding pattern disposed across a face of the print medium, said linear data track identifying at least a print media identifier, said two-dimensional coding pattern identifying at least the print media identifier and a plurality of locations in a two-dimensional coordinate grid;
• printing the first information onto the print medium using a printer module of the mobile telecommunications device;
• automatically reading the data track during said printing using an optical encoder positioned in a media path of the printer module;
• decoding the read data track to determine the print media identifier;
• communicating the print media identifier to a computer system, thereby causing the computer system to associate the print media identifier with the printed first information so as to create a linked page description;
• interacting with the print medium and sensing part of the two-dimensional coding pattern using a sensor module of the mobile telecommunications device;
• decoding the sensed coding pattern to determine the print media identifier and a two-dimensional coordinate position;
• and
• retrieving, using the mobile telecommunications device, the decoded coded pattern and the linked page description, at least one of:
• the first information and second information identified by said linked page description.
