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.

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
