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

Subject
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
