RE: Fax processing confirmation


Thank you very much for detailed information about the IPP notification
that it does not support page by page confirmation from the receiver.
Fax wg should discuss about fax processing status.
PWG IPP FAX WG may discuss about the fax processing status also.

Hi Dan and IFax folks,

Please note that IPP notifications (in-band via IPP channel
or out-of-band via SMTP or 'reverse' HTTP) are still
work-in-progress in the IETF IPP WG.

IPP native protocol itself does NOT provide confirmation that
any pages have actually been printed without polling (by the
IPP Client) of the IPP Printer.

The IEEE/ISTO PWG (Printer Working Group) has chartered IPPFax
project, but it isn't very far along yet.  The IETF declined
to charter IPPFax as an IETF WG, so this is probably quite
far away from an IETF 'standards track' RFC.

IPP provides this sort of confirmation today. Why not use IPP?
