    Hi Harry,

    Not a flat set - we already had a multi-attribute set of (at least):

    1) print-quality
    2) printer-resolution
    3) media

    They interact to produce the desired print quality, as Pete observed.

    Having said that, since "print-content-optimize" now ONLY enumerates
    document content metadata, yes I'd be happy to add another new
    attribute:

        print-ink-save (boolean)

    Bob Taylor and others have correctly pointed out that 'toner' is
    only used in laser printing - 'ink' or 'marker' or something else
    is used in the other printing processes.

    Cheers,

    My concern is that "save toner" is probably the most concrete concept
    compared to "Good, Better, Best" or "Text, Image, Graphics". The later has
    efficient application only in special cases (some of which may be very
    significant, like printing photo's). Otherwise, people stare at their mixed
    object document and wonder. I feel "save toner" should be explicit.

    We went from a flat set of descriptors to a pairing.. perhaps we should
    really go to a matrix (although I don't like the perceived complexity)

    Good - Better - Best
    Text - Text+Graphics - Graphics - Image

    Harry,
    We felt that there are many different attributes involved in heuristics for
    saving toner and printing fast. Some of those are "resolution", "media" and
    aspects of the document content. We felt the requirements were met by
    keeping the existing "print-quality" values and augmenting them with hints
    on how to process the document content to achieve 'draft' 'normal' and
    'high'. The assumption is that draft is fastest and uses the least toner.

    I think this warrants further examination. I have known toner saving methods
    that do a very good job of preserving print quality.

    All,
    During the PWG/FSG meeting in Portland we had a discussion about the IPP
    "print-quality" attribute and FSG's desire to add two new values, 'economy'
    and 'fine', where 'economy' is lower than 'draft' and 'fine' is higher than
    'high'. The FSG further proposed the addition of a new attribute, called
    "print-optimize", that would augment "print-quality" with values of 'image',
    'photo', 'text', 'text-and-image', 'save-toner' and 'speed'.
    With regard to 'economy' and 'fine', we agreed that 'economy' would map to
    "print-quality"='draft' and 'fine' to "print-quality"='high'. There may be
    end user visible features that map to multiple attributes. We leave it to
    specific print domains to model these higher level aggregate features. When
    appropriate we will add needed elements to the Semantic Model.
    There was a lot of push back on "print-optimize". The main concern was that
    "print-optimize" contained a mixed bag of items. The two main categories
    were content metadata and rendering hints. We finally agreed that the two
    values 'save-toner' and 'speed' are implied by the "print-quality". Since
    they were not required, they were removed. The remaining values are needed
    to direct the type of optimization/processing that will be performed on the
    content. It does not necessarily mean the value describes the content. To
    clarify this we changed the attribute name to "print-content-optimize".
    Finally the value 'image' seemed the same as 'photo'. The name for this was
    changed to 'graphic'.
    As a result the following attribute will be added to the JobX specification
    in it next revision.
       print-content-optimize (type2 keyword)
          This attribute refines the value specified by the print-quality
          attribute.
          The standard keyword values are:
             'graphic': optimize for graphic clarity
             'photo': optimize for photo clarity
             'text': optimize for text clarity
             'text-and-graphic': optimize for both text and graphic clarity
