Abstract:
1. A method of printing program information onto a print medium and retrieving a program state using the print medium, the program state being associated with a region of the print medium, said method comprising the steps of: providing a print medium having first coded data in a first format and second coded data in a second format, the first coded data encoding first information and the second coded data encoding second information, at least some of the first information being indicative of a print media identifier, the first format being a linear data track extending along a side of the print medium, at least some of the second information being indicative of the print media identifier and of a two-dimensional coordinate grid, the second format being a two-dimensional pattern, with the print media identifier identifying the print medium; printing program information onto the print medium using a printer module of a mobile telecommunications device; reading the data track during said printing using an optical encoder of the printer module, said optical encoder being configured for automatically reading said data track during said printing; 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 program information; reading, using a sensor module, at least some of the second coded data; determining the print media identifier and a position of the sensor module relative to the print medium by decoding the sensed second coded data; and, retrieving, if the determined position is within the region, the program state from the computer system using the mobile telecommunications device and the determined print media identifier.
