All,
This message starts the IPP workgroup last call of the Supporting Multi-Purpose Trays best practice document which can be found here:
http://ftp.pwg.org/pub/pwg/ipp/wd/wd-sweet-mptray-20171127.pdf
This best practice document provides implementation guidance for supporting so-called "multi-purpose" trays in printers. The document was reviewed at the last IPP workgroup conference call and was deemed ready for last call.
Please review this document and respond to the IPP mailing list (reply-all to this message is fine) with any feedback you have for the proposed best practice.
This last call ends at 10pm PT on January 24, 2018.
