<br>Below is ABNF for new "printer-input-tray" and "printer-output-tray"<br>string attributes (i.e., 1setOf (octetString) since they're fixed in<br>
UTF-8 only and not variable charset).<br><br>They are based on Printer MIB v2 conformance requirements, media source<br>key properties, and DMTF CIM ranking activity by WIMS WG in 2006. The<br>reference for that activity (I think we should add as an Informative<br>
reference) is:<br><br>DMTF CIM Ranking of Printer MIB v2 Objects, WIMS WG, September 2006,<br><a href="ftp://ftp.pwg.org/pub/pwg/wims/cim/" target="_blank">ftp://ftp.pwg.org/pub/pwg/wims/cim/</a><br> PrinterMibObjectsToAdd_conclusions_20060921_F.pdf<br>
<br>Mike - note the attribute conformance tables have been included. Also<br>note I fixed the table headers to more accurate "Printer MIB Object".<br><br>Comments?<br></blockquote><div><br></div></div>OK, so I am concerned that we are providing input tray information in two different places. The current media-col-ready attribute provides most of the information in printer-input-tray - as of JPS3 the only missing information is the current level, max capacity, capacity unit, and status. Seems like we could simply add those to the media-source-properties (or a new media-status) collection member attribute instead?</div>
<div><br></div><div>As for printer-output-tray, I'm not sure how a Client could correlate the values with output-bin/output-bin-default/output-bin-supported? I almost think we want an output-bin-ready or output-bin-status 1setOf collection attribute instead that correlates the output tray information to output-bin values.</div>
