    I think you are correct to point out that an absolute minimum implementation
    of IPP does not make it a good IPP implementation. A lot of the IPP
    functionality that distinguishes it from past de facto standards and
    proprietary implementations fall into the "optional " category. If everybody
    only bothers to implement the absolute minimum, IPP is not going to have a
    major impact as replacement for the "old" printing technologies and we have
    wasted a lot of our time....

    Okay, I'm obviously landing in the middle of a long discussion.
    Apologies if I'm covering old ground.

    What you describe is very, very sad. Anyone who's worked with
    lpr/lpd, and tried to deliver status or completion results has
    cursed this deficiency in lpr/lpd -- the completed job vanishes.
    Now here we are 25 years later, and we're propagating the same

    Moreover, we're trying to patch the problem with
    machine-readable e-mail notification? If this is important (and
    it is), let's address the underlying problem.

    And please don't anyone tell me about their $99 printer for
    remote internet printing that can't cache a reasonable amount of
    completed job status but does have the resources to deliver
    multi-part MIME e-mail. ;-)
