    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.},
