    This limitation seems a bit restrictive, particularly since the IPP Model
    doesn't even define a server object.

    I thought of a couple of ways to do a more general, true Move-Job operation
    (maybe these have already been discussed and I've missed it). Given a
    Client, an Old Printer, and a New Printer, the object is to get the job
    from the Old Printer to the New Printer.

    1) A Move-Job request sent from the Client to the Old Printer causes the
    Old Printer to become an IPP client to the New Printer. The Old Printer
    sends a Print-Job request to the New Printer. When the Old Printer
    receives the Print-Job response from the New Printer, it returns this to
    the Client as the Move-Job response. (If the job was accepted, this
    response includes the new job-printer-uri, job-id, and job-uri, so the
    Client can now track the job on the New Printer.)

    2) Instead of a new Move-Job operation, define two new operations: one
    which "inhales" the Job from the Old Printer into the Client, and another
    which "exhales" it from the Client to the New Printer. What should these
    new operations be called? Hmm, ..., ... ! IPPness indeed! On second
    thought, maybe the exhale operation is redundant: the client could just do
    a Print-Job. So, all we need is a new Get-Job operation that allows the
    Client to pull the complete Job back from the Old Printer so that it can be
    sent to the new Printer with a Print-Job request.

    Okay, what are the fatal holes in these proposals?
