But I'm saying that there's no guarantee that you can even verify that the bits (the document data) were successfully received. The Printer may respond after processing the IPP attributes, before the document data was even transmitted.

At the bakeoff, I seem to remember that a certain client implementation was confused when jobs that had been canceled hung around. Maybe this recollection is faulty. Anyway, there is no guarantee in the standard that completed, aborted, or cancelled jobs will be retained for any length of time.
