- Job submission attributes supported/required
      - scheduling attributes (e.g. priority)
      - production attributes (e.g. number of copies)

5.5. ASYNCHRONOUS NOTIFICATION

   Client                                               IPP Printer

    +----------------------------------------------------------- >
       Use the following method to notify me of Printer events

                                 .
                                 .
                                 .
    < -----------------------------------------------------------+
        Asynchronous notification of Printer event

   Clients must be able to request asynchronous notification for Printer
   events such as

   - job completion
   - a fatal error that requires the job to be resubmitted
   - a condition that severely impacts a queued job for this client
      e.g. printer is out of paper

   Note: end-user notification is a V1.0 design goal while operator
   notification is for V2.0.

5.6. JOB CANCELING

   Client                                               IPP Printer

    +----------------------------------------------------------- >
       Cancel the named job as indicated


    < -----------------------------------------------------------+
        Response (did it or not)

   Similarly clients must be able to make changes to jobs which have
   been submitted and are queued for printing.  Changing of job
   attributes should also be supported.  Job modifications, holding and
   releasing of jobs are not included in the design goals for IPP v1.0.
