  • Next message: McDonald, Ira: "RE: PMP> Printer MIB draft-11 posted at PWG site (10 January 2002 )"

    Bert,

    Our latest version MIB is now *finally* available at:

    http://www.ietf.org/internet-drafts/draft-ietf-printmib-mib-info-11.txt

    Unfortunately, the posted version is missing form feeds. Ira McDonald has a
    version that contains the missing form feeds and is also planning to run it
    through David Perkins' "mstrip" tool to extract the MIB. I can send to you
    either the version with form feeds and/or the stripped MIB if don't want to
    deal with unfriendly version that was posted.

            Ron Bergman

    I did not yet look at the new rev (too busy preparing for
    IETF... and I bet Dave Harington is in same situation).

    Why don;t you post the new draft as soon as repository opens up
    again and then we'll review.

    Bert
