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

    IPP> Print Quality Issue resolution

    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
