Hi, Please review and send us comments on the IPP over HTTPS Transport Binding and 'ipps' URI Scheme and available at: http://tools.ietf.org/id/draft-mcdonald-ipps-uri-scheme-03.txt Many thanks again to Mykyta Yevstifeyev for his helpful comments on the previous draft. Abstract: This memo defines the Internet Printing Protocol (IPP) over HTTPS transport binding and the corresponding 'ipps' URI scheme, that is used to designate the access to the network location of a secure IPP print service or a network resource (for example, a print job) managed by such a service. This memo is published by the IETF on behalf of the Internet Printing Protocol Working Group of the IEEE-ISTO Printer Working Group. This memo updates RFC 2910 and RFC 2911. Background: This memo is published by IETF on behalf of the Internet Printing Protocol Working Group of the IEEE-ISTO Printer Working Group, as part of their IPP Everywhere [IPPEVE] project for mobile, driverless, ubiquitous printing. http://pwg-wiki.wikispaces.com/IPP+Everywhere IPP/1.1 [RFC2911] is now ubiquitous (i.e., supported by all network printers shipped in the last decade). IPP/2.0 (workgroup), IPP/2.1 (enterprise), and IPP/2.2 (datacenter), all defined in [PWG5100.12], are now being deployed. However, many IPP implementations don't support the TLS upgrade (OPTIONAL for conformance in RFC 2910/2911). And some IPP implementations don't immediately upgrade at connection startup (which is non-conforming). This situation has discouraged the use of IPP over public Internet connections. The IPP Everywhere project [IPPEVE] of the IEEE-ISTO PWG mandates the use of TLS for *all* connections. Therefore, a given 'ipps' URI is translated by identity (over port 631) into an 'https' URI (RFC 2818) - see section 3.2 of this memo. 'ipps' URI values also must use UTF-8 (RFC 3629). The 'ipps' URI scheme has been deployed for many years in [CUPS] - the most widely deployed implementation of an IPP print service - CUPS is the default print spooler on Mac OS X, Linux, and most UNIX versions and is also available on Windows and other operating systems.
