The usual common options are:
You can get the supported values via IPP and/or HTTP requests,
and they can be defaulted pretty easily when printing without
CUPS. Also, CUPS supports embedded "job tickets" in PS files like:
%cupsJobTicket: media=a4 sides=two-sided-long-edge
so you can pass the options that way if you like and use a
common print command path.
I'd be happy to work with you on this, provide sample code, etc.
My flPhoto software (http://www.easysw.com/~mike/flPhoto/) does
some of this to provide printing with and without CUPS...
Also, there is a print API being defined by the Free Standards
Group called PAPI which supports CUPS, Berkeley LPR/LPRng, and
System V LP which would allow you to use a common API to get a
list of available destinations and their common options, and submit
