Hi Ira,

I think you might be interested in the e-mail exchange appended below
because it brings up the question (maybe an extension of the point made by
Chris Story of Ricoh at the just concluded PWG F2F) of how reliable the
proposed CIM and MFP Alert mechanisms will really be in the field when as
mentioned in the attached e-mail discussion it is possible for a printer to
issue different informative responses, for the SAME printer condition,
depending upon whether an application has queried it via its internal web
browser or its MIB.
