Ira,

I am confused about the messages from PWG concerning media size names in the
Printer MIB and IEEE-ISTO 5101.  In particular, in the Printer MIB,
shouldn't prtInputMediaName reference IEEE-ISTO 5101.1 in preference to
Appendix C.  And it seems that the Self-Describing Name should be encouraged
as the default MediaName.

Also, please note that the last line of the first paragraph of Appendix B
uses the object name prtMediaDimFeedDir.  I believe you mean
prtInputChosenMediaDimFeedDir.

Thanks for pushing the Printer MIB through the process.

Mark Hopkins

Hi folks,

I just posted the latest version of Printer MIB v2 (draft-11) at the
PWG FTP server - this copy DOES have the formfeeds (page breaks), so
it prints and views better.  And I extracted and compiled and verified
the ASN.1 for the MIB.

To the best of our knowledge this version corrects all problems that
Bert Wijnen, David Harrington, and Juergen Schoenwaelder have found.
The editors believe this document is now ready for publication as an RFC.

At the PWG anonymous FTP server in the directory:

    ftp://ftp.pwg.org/pub/pwg/pmp/drafts/

in the files:

    draft-ietf-printmib-mib-info-11.txt -- full document w/ formfeeds

    draft-ietf-printmib-mib-info-11.mib -- extracted ASN.1 for MIB

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

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.
