A system for enabling user interaction with computer software. The system includes a printer for receiving print data, printing a form, using the print data, with information related to an interactive element coincident with coded data indicative of the interactive element, receiving indicating data from a sensing device which is generated by the sensing device sensing the coincident coded data so as to be indicative of the interactive element, and transfer the indicating data to a computer system to allow the interaction to be interpreted. The coded data is indicative of an identity. The computer system determines, using the indicating data, the identity, determines, using the identity, a page description, and identifies, using the page description, the interactive element.
