Patent ID: 7697157

Claim:
A document retrieval device for retrieving a second interactive document in response to first indicating data received from a sensing device, the first indicating data being generated by the sensing device using first coded data disposed on a first interactive document, said first interactive document having a corresponding page description stored in one of a plurality of servers, the document retrieval device being configured to: (i) receive, from the sensing device, the first indicating data, the first indicating data identifying a page identity and one or more locations on the first interactive document; (ii) use the page identity contained in the first indicating data to determine a network address of a server handling the page description corresponding to the first interactive document; (iii) send second indicating data to said network address identified using the page identity, said second indicating data being based on the first indicating data, wherein receipt of said second indicating data by said server initiates a request for said second interactive document; (iv) receive response data corresponding to the second interactive document; and (v) providing the second interactive document to a user; wherein the document retrieval device comprises a printer for providing the second interactive document to the user; the second interactive document has second coded data, said printer includes a coded data generator configured to generate the second coded data based at least partially on the response data, the second coded data being usable by the sensing device to generate third indicating data for initiating an action.
