System for facilitating searches for data stored on a network
First Claim
1. A system for facilitating searches for data stored on a network, the system comprisinga computer system forming a node on the network and having a database of electronic documents, each of which are associated with at least one resource description;
- a printer connected to the network, said printer being configured to;
receive first print instructions from the computer system;
print a first document representing a first electronic document, said first printed document containing graphical information relating to the search to be carried out and coded data printed as a collection of tags, each tag identifying an identity of the first printed document and a location of the tag on the first printed document, said coded data being printed with said graphical information by said printer;
receive data from an optically imaging pen reading the first coded data, said data being indicative of the identity of the printed document and a position of a nib of the pen, the position of the nib being calculated using a first position determined from decoding an imaged tag, a perspective distortion observed on the imaged tag and a known spatial relationship between an optical axis and the nib, wherein the first position is different from the nib position;
receive second print instructions from the computer system in response to the received data; and
print a second document containing information identified by the computer system.

Abstract
A system for facilitating searches for data stored on a network includes a computer system forming a node on the network and having a database of electronic documents, each of which are associated with at least one resource description. A printer is connected to the network for receiving print instructions from the computer system to print a first document representing one of the electronic documents such that the first document carries information relating to the search to be carried out and coded data representing at least an identity of the printed document. A sensing device is capable of sensing the coded data and is operatively connected to the printer to write data representing the identity of the printed document to the computer system, via the printer and the network, the computer system being programmed to retrieve information from the network based on the resource description and to instruct the printer to print the information on a second document.
