Mike, Pete, (All)
So, should the PJT not specify both but rather specify one or the other?
I know that for the PJT, that "quality" is required while "resolution"
is optional. So if "quality" is required and always wins; what is the
value or need for "resolution"? The spec's do not have a value of
"unknown" or "other" for "quality"; so, the Print Service will not ever
use the "resolution" information and, in fact, the "resolution" data
simply adds confusion.
However, if "quality" and "resolution" were made either-or-but-not-both,
then a client could specify either without a "winner". The other
option is add the values "unknown" or "other" to "quality" which directs
the Print Service to use "resolution".

Glen,
This is covered in IPP/2.0; basically if there is a conflict between
resolution and quality, quality wins.
As far as PWG Raster goes, that is a separate capability
(PwgRasterDocumentResolutionSupported) that expresses the capabilities
of the input side of the printer's imaging engine, while Resolution
expresses the capabilities of the output side of the printer's imaging
engine.
(i.e. a printer might only accept 360dpi raster data but print it at
2880dpi...)

I remember a discussion about resolution versus quality (I think the PWG
raster discussions). I thought that is quality and resolution did not
agree (as interpreted by the print service capability/definition) then
quality was to be used. In the PJT should resolution and quality be
denoted as either but not both? Or at least should a note be added?
