Is the intent that all printers will use a resource path of “/ipp/faxout” or is the spec missing mention of the “rfo=/ipp/faxout” mDNS TXT record for determining the IppFaxOut resource path to use?
The FaxOut spec was written before the TXT record variable was defined/used, and then for AirPrint. I've filed an errata issue against 5100.15 to add a DNS-SD section:
https://www.pwg.org/dynamo/issues.php?U131
FWIW, except for print servers (where there would be multiple "queues") the resource path is expected to be "/ipp/faxout". From 5100.15:
4.1.5 Printer URIs
Each instance of an IPP FaxOut service is identified by a URI. The path component of an IPP FaxOut URI MUST be “/ipp/faxout” for the only (or default) instance of the service on an Imaging Device and “/ipp/faxout/instance-name” for each additional, non-default instance on the Imaging Device.
Thanks for noticing this and speaking up!
