IPP> Print Quality Issue resolution

My goal is not to make things more complicated so I would propose 
"print-ink-save" and let the implementation decide what or how, as you 
suggest. My main point is that "toner-saver" is too concrete a concept in 
too many implementations for it not to be explicit. 

As far as choosing a name - Toner, vs, Ink, vs Glop... whatever...

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
