Peter,
 
Seems  a reasonable resolution. However,  since you  state:
...the value 'image' seemed the same as 'photo'.  The name for this was changed to 'graphic'.
 
I  do not understand why the values  include both "Graphic" and "Photo".:
 
         '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

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
