ABSTRACT:
A method of communicating between a print client and a print server is described. The method comprises obtaining an indication of the viability of communication of User Datagram Protocol (UDP) messages from the server to the client. If the indication is that UDP messages are viable, messages are sent from the server to the client using UDP. Otherwise a Hypertext Transfer Protocol (HTTP) request is made from the client to the server, that request is left open, and when the server wishes to send a message to the client, the message is sent as the response to the open HTTP request.
