>My main question with TonerSaving/InkSaving/MarkerSaving is how this is

To answer this question, straightforward, there are implementations where
you can select High|Normal|Draft independently from "Saver".
Administrators may want to configure policy that "Saving" must always be
on yet still allow the choice of High|Normal|Draft, within that context.
>PrintQuality=High & MarkerSaving=False would seem to say "print in high
quality, and waste toner/ink for no good reason
I think people would expect:
PQ=High|Saving=Off to result in the BEST possible quality.
PQ=High|Saving=On to result in the best possible quality while still
saving marker (toner, ink ...)
PQ=Draft|Saving=Off to result in the FASTEST possible printing
PQ=Draft|Saving=On to result in the fastest possible printing with
legibility that may not stand up to close scrutiny because marker (toner,
ink...) has been used sparingly.

RE: [printing-driver] RE: IPP> Print Quality Issue resolution
My main question with TonerSaving/InkSaving/MarkerSaving is how this is
any different than PrintQuality(High|Normal|Draft). We as well have nifty
algorithms for saving "marker" without impacting quality - but I don't
know why we'd ever want to turn it "off" seperately from the notion of
PQ/performance/economy tradeoff (which I maintain is what PrintQuality
actually is). The semantics of this as a separate attribute seem somewhat
odd to me - i.e., PrintQuality=High & MarkerSaving=False would seem to say
"print in high quality, and waste toner/ink for no good reason", and
PrintQuality=Draft & MarkerSaving=False would seem to say "print in poor
quality, but waste tone/ink anyway". IMHO, a "separate" TonerSaving mode
is really a vendor-specific extension of PrintQuality, which as Ira noted
as already supported (though they are supposed to be IANA-registered,
which I'm guessing most vendors have not bothered to do).
thanks,
bt

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

RE: IPP> Print Quality Issue resolution
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
