1. An Internet printing method comprising:
- providing a proxy unit on the Internet;
opening a server site of a print server according to a request from a client and/or the print server, the server site being opened in the proxy unit;
accessing the server site by the client; and
converting a protocol into a protocol which allows circumventing a firewall of the print server, and transferring a printing service request from the client to the print server,wherein the firewall is provided between the print server and the proxy unit.

Abstract
The Internet printing system for a client perform printing out to a print server that cannot circumvent a firewall by the Internet Printing Protocol (IPP). For a print server which cannot circumvent the firewall by IPP, a proxy unit which can communicate using IPP is installed on the Internet. A server site of the print server is opened on the proxy unit, and an IPP client regards the print server as a public IPP server opened on the Internet, and exchanges printing service requests and responses via the proxy unit. Since the proxy unit performs gateway conversion from IPP into another protocol, the client can print out to the print server circumventing the firewall by using IPP.

10. An Internet printing system comprising:
-
a client that communicates at least by using the Internet Printing Protocol; a print server that is protected by a firewall on the Internet and for executing a printing service request; and a proxy unit that opens a server site of the print server according to a request from the client and/or the print server, converts the Internet Printing Protocol used by the client for sending the printing service request into a protocol which allows circumventing the firewall of the print server at the access of the client to the server site, and transfers the request to the print server, wherein the firewall is provided between the print server and the proxy unit. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A proxy unit comprising:
-
a server site of a print server to be opened according to a request from a client and/or the print server; and an exchanger that converts a protocol used by the client for sending a printing service request into a protocol which allows circumventing a firewall of the print server at an access of the client to the server site, and transfers the request to the print server, wherein the firewall is provided between the print server and the proxy unit. - View Dependent Claims (18, 19, 20, 21)

22. A printer server comprising:
-
a network interface for communicating; and a processor that requests to a proxy unit installed on the Internet to open a server site of a print server, and receives a printing service request from the proxy unit where a protocol used for a printing service request of the client is converted into a protocol which allows circumventing the firewall of the print server at the access of the client to the server site, and executes the printing service request, wherein the firewall is provided between the print server and the proxy unit. - View Dependent Claims (23, 24)
