    Harry,

    I think that it is a good time to publish the PWG Production Printing
    extensions as a PWG Draft standard, because of its relationship with JDF
    which is just about to publish its 1.0 version. Having the PWG Production
    Printing Instructions being progressed through the PWG (and they've past
    Last Call - twice), was the major reason that we were able to get JDF to add
    Integrated Digital Printing (called IDPrinting) process into JDF and to add
    the Appendix that maps IDPrinting to IPP.

    The printing part of JDF is primarily for production printing.

    Thus IPP and the PWG Production Printing extensions have had an impact on
    JDF and the Appendix maps JDF to IPP, including the PWG Production Printing
    extensions. If the PWG doesn't go forward with publishing the PWG
    Production Printing standard, then the JDF folks will probably have to
    delete their appendix and most of the IDPrinting process. That would be a
    real step backward and would leave IPP and JDF with no commonality.

    Thanks,
    Tom

    Nonetheless, with JDF still in development, is this a good time to
    progress such a "production" intensive extension to IPP?

    Harry,

    The PWG Production Printing documents have been published since January
    2000
    on the PWG server.

    However, we didn't really address them until the September meeting. The
    minutes contain the following:

    2.5 Production Printing

    Carl-Uno referenced the JDF activity [www.job-definition-format.org] that
    has received much attention at the Seybold Conference. According to
    Carl-Uno, there is an ongoing attempt to get the JDF effort to adopt the
    IPP
    semantics.

    2.6 Production Printing Attributes

    Tom Hastings led a review of the latest draft of the Production Printing
    Attributes document:
    ftp://ftp.pwg.org/pub/pwg/ipp/new_PPE/pwg-ipp-prod-print-set1-000605.pdf
    It was suggested that a "force new sheet" attribute should be added. A
    capability for defining "flush-left/right/top/bottom" was also suggested.

    It was agreed that "x-image-auto-center" and "y-image-auto-center" will be
    replaced by "x-image-position" (left/right/center) and "y-image-position"
    (top/bottom).

    "Job-recipient-name" and "media-weight-english" were removed from the
    document.

    It was suggested that the protocol include the specification of both input
    tray and media size. A "media-by-tray" attribute will be added.

    During the review, Tom noted various other minor modifications that were
    suggested and agreed. He will update the document and issue the next draft
    before a PWG Last Call.

    3.4 Presentation Direction

    Bob explained two new [Job Template]
    attributes-"presentation-direction-requested" and
    "presentation-direction-number-up"-that he proposes for additional
    control.

    It was agreed that presentation-direction (as it applies to number-up)
    will
    be included in the updated Production Printing Attributes document.

    We also reviewed the document again at the December IPP WG meeting (which
    you were unable to attend). Those minutes contain:

    2. Administrivia
    · Final voting process to start to become PWG standards:
    * IPP Production Printing Attributes - Set1
    * IPP Override Attributes for Documents and Pages
    * IPP "output-bin" attribute extension
    * IPP "finishings" attribute values extension

    10.1 IPP Production Printing Attributes - Set1

    Tom Hastings announced that Xerox has discovered a few problems with
    Impression Image Shifting Attributes in this document and would like to
    delay its progression to PWG Standard. They would like to include more
    terms, attributes, and clarifications in Section 3.18. Tom explained the
    new
    attributes and described several methods of placing impressions on paper.
    The proposed modifications have not yet been distributed for review,
    but Tom plans to issue a new draft soon.

    We discussed the image shifting by drawing pictures on the flip chart
    easel
    to verify that the distinctions between imposition and signature printing
    agreed with industry practice.
    I hope this helps answer your concerns about the time we've spent on them.

    Thanks,
    Tom

    Subject: PWG-IPP> IPP Production Printing Attributes

    As the vote for IPP Production Attributes nears, I would like to reiterate

    several concerns I have had throughout the life of this draft.

    1. As a PWG draft, this topic does not seem to have received the same
    level of attention and discussion (ex. in f2f meetings or on the wire) as
    have the IETF related efforts (Notifications, Security, Bakeoff's etc.).
    While the document has received a couple short reviews, it is my opinion
    that these have been overshadowed by broader issues at the f2f meetings.

    2. The document introduces numerous concepts such as page ordering, image
    shifting and finishing features, some of which are fairly exotic. Granted,

    the scope of this proposal is "Production" but I wonder if this narrow
    scope may have resulted in less than broad participation in actually
    reviewing and digesting this document.

    3. There are other industry consortia addressing similar areas. The CIP4 -

    JDF is one example. There has been no formal PWG effort to assure harmony
    or compatibility between JDF and IPP Production Attributes.
