Internet printing lets you display printers on Web pages so that printers can be viewed managed and used across the Internet or an intranet. If you enable this policy setting Internet printing is activated on this server. If you disable this policy setting or do not configure it Internet printing is not activated. Internet printing is an extension of Internet Information Services (IIS). To use Internet printing IIS must be installed and printing support and this setting must be enabled. Note: This setting affects the server side of Internet printing only. It does not prevent the print client on the computer from printing across the Internet. Also see the "Custom support URL in the Printers folder's left pane" setting in this folder and the "Browse a common Web site to find printers" setting in User Configuration\Administrative Templates\Control Panel\Printers.
