Windows 2000 uses the Internet Printing Protocol (IPP) to interpret a URL to identify printers and submit print jobs. This protocol allows users to send documents to any printer on a Microsoft Windows 2000 network that is connected to the Internet. Internet printing is beneficial because a user can print to a URL over an intranet or the Internet, view printer and job related information in Hypertext Markup Language (HTML) format, and download and install printer drivers over the Internet. When you access a printer from a browser, Windows 2000 first attempts to connect to the printer with a remote procedure call (RPC). If the RPC connection is unsuccessful, Windows 2000 uses the IPP protocol encapsulated in a HTTP (Hypertext Transport Protocol) packet as its carrier to connect to the printer. Hypertext Transport Protocol (HTTP) is the method by which World Wide Web pages are transmitted over the Internet.
