Maeda-san,
I think Ira McDonald's message may have been misunderstood. The IPP
notification may still be "work in progress". But, as indicated by the IESG
message below, the basic mechanisms are up for last call. These documents,
although they deal with many possible notification events and mechanisms, do
include "page by page confirmation from the receiver" (or more exactly,
sheet by sheet confirmation.)
Further, although various notification mechanisms are identified, it is
assumed that sheet-by-sheet job progress notification is applicable
primarily to real-time notification connections which include the "indp"
method <draft-ietf-ipp-indp-method-03.txt> as well as the "get" method
<draft-ietf-ipp-notify-get-01.txt> alluded to by Ira.
I suggest that the IP FAX community may be interested in commenting on these
notification approaches.
I would also suggest that the various IFAX approaches each have advantages
in certain environments. T.37 uses virtually universal EMAIL capabilities.
T.38 (non-gateway) uses voice over IP, which suggests a voice/fax
capability. IPP has great flexibility, it can utilize developments in its
host HTTP protocol, and provides for authentication and encryption. It is
unclear that internet fax must settle on a single protocol.
The IESG announcement, dated Mon 2/19/2001. follows.
"The IESG has received a request from the Internet Printing Protocol
Working Group to consider Internet Printing Protocol (IPP):IPP Event
Notification Specification <draft-ietf-ipp-not-spec-06.txt> as a
Proposed Standard.
The IESG will also consider publication of Internet Printing Protocol:
Requirements for IPP Notifications <draft-ietf-ipp-not-05.txt> as an
Informational RFC.
The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send any comments to the
iesg@ietf.org or ietf@ietf.org mailing lists by March 5, 2001.
Files can be obtained via

Ira-san
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.
Regards.
