    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.

    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.

     

    Tom

    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"?)
