     Internet Printing Protocol (IPP) over HTTPS Transport Binding
                       and the 'ipps' URI Scheme

Abstract

   This document defines the Internet Printing Protocol (IPP) over HTTPS
   transport binding and the corresponding 'ipps' URI scheme, which is
   used to designate the access to the network location of a secure IPP
   print service or a network resource managed by such a service.

   This document defines an alternate IPP transport binding to that
   defined in the original IPP URL Scheme (RFC 3510), but this document
   does not update or obsolete RFC 3510.

   This document updates RFCs 2910 and 2911.
