Hi Tom,
I've been mulling this topic and I believe that media-ready was required
because we were going to require the client to format the job based on
the size of the paper that could be printed (sender makes right).
However, now that we allow scaling and that we are focusing
repositories, maybe this requirement can be lifted.

Subject: RE: IFX> Media-Ready [and is IPPFAX a Device Protocol or an
Electronic Document Exchange Protocol?]
Gail,
I suspect that the reason that the IPPFAX spec says that the Receiver
MUST support "media-ready" was because the spec says that the IPPFAX
Sender SHOULD query the "media-ready" Printer attribute.
I also think that the mind set of IPPFAX had been a single Device, so
that the fan-out to multiple devices wasn't even a consideration in
being difficult to reflect the "media-ready" value(s) correctly. For
example, the statement in the Introduction:
"The target market for an IPPFAX receiver is a midrange imaging device
that can support the minimum memory requirements that are required by
the data format PDF/is, but the image format is structured in such a way
that the Receiver is not required to include a disk or other permanent
storage."
On the other hand, the definition of Receiver is:
"Receiver The Printer object that accepts IPPFAX protocol operations
and receives the Document sent by the Sender. A Receiver offers the
IPPFAX Print Service (by definition)."
So the real question is:
OK that the IPPFAX Sender not bother with querying "media-ready", but
should send the IPPFAX PDF/is document whether the media is ready or
not?
If the Sender doesn't query "media-ready", then the IPPFAX protocol is
an Electronic Document Transfer Protocol, i.e., get the bits from the
Sender to the Receiver, rather than get the Quality Document
Successfully Printed onto Paper Service. The mind set of the WG does
shift from one paradigm to the other from time to time (and from place
to place within the IPPFAX Protocol spec itself).
As another example of this vacilation between defining a Device Protocol
versus an Electronic Document Exchange Service, is the idea that the
IPPGET notification is going to indicate whether the paper got printed
OK. To me that means we are talking about getting the document
successfully transferred to paper. Therefore, with that mind set,
having the Sender query the "media-ready" makes a lot of sense if the
Sending User cares about knowing for certain that the document was
correctly imaged onto paper.

Subject: IFX> Media-Ready
At Wednesday's telecom, we discovered that Media-Ready was Required in
one spot and optional in another. Ira was of the opinion that it should
be PROHIBIED.
Does anyone else have opinion (or remember why it was "Required"?)
