    Hi Juergen,

    While you're correct that we should define another column
    in 'prtInterpreterTable' to disambiguate this units problem,
    that's not very practical.

    The actual objects (very few) newly defined in Printer MIB v2
    have all been stable for four or five years. Several printer
    vendors have been shipping full Printer MIB v2 implementations
    for two or three years. The tools all understand the current
    objects in Printer MIB v2. Adding an object now would be
    unpopular in the extreme.

    Vendors - is adding a new column to 'prtInterpreterTable'
    (the technically correct solution) acceptable?

    Ron and Harry - I'm personally ambivalent about this issue.
    Juergen has uncovered a non-trivial bug in the Printer MIB
    (v1 and v2).

    Cheers,
    - Ira McDonald, co-editor of Printer MIB v2

    Are you sure this is always and necessarily the right marker?

    What ever the answer is, it should be documented. As far as I am
    concerned, I would like to see another column

        prtInterpreterFeedAddressabilityUnit

    added to the prtInterpreterTable and the need for looking up the unit
    in some other places just goes away.

    Right now, the MIB seems to allow for it and hence I try to allow for
    this in my management application...
