A method of performing data searches on a network includes the step of maintaining a database of electronic documents on a computer system forming a node on the network, such that each electronic document is associated with at least one resource description. Search form print data is generated at the computer system such that the search form carries information relating to at least one parameter of a search to be carried out and coded data associated with that information. Print instructions are received from the computer system at a printer via the network. The search form is printed at the printer. The coded data is sensed at a sensing device operatively connected to the printer. Search instructions generated by the sensing device are written to the computer system, via the printer and the network. A search is carried out on the network, in response to the instructions, based on the, or each, parameter. Search result print data is generated at the computer system, representing the results of the search.
