I don't know.  I thought the whole idea of GNUstep was that it was 
supposed to be the part with abstraction.  Let me further explain what 
my main goal of GSCUPS is.
I want to gnustepize the libcups api, the part that deals with managing 
the printing system.  I'm talking adding printers, removing them, 
connecting to printers on the network stuff like that.  The idea is 
that GSCUPS will be foundation of something like OS X's "Print 
Utility".  I wasn't actually thinking of it being used for actually 
sending print jobs.   But I suppose it could.

Let me explore the NSPrint* structure a little bit more.  I've looked 
at at NsprintInfo and NSPrinter, they seem to do all lot of work that 
CUPS can do instead, perhaps better as well.  It would seem like a good 
idea to simply change those so they interface with CUPs, but what then 
about windows?  Maybe a front/back-end system is needed.

I'm not sure I have the expertise to create such a front-end correctly. 
 However, I think that I would be able to create a CUPS back-end.


CUPS seems pretty standard now for all UNIX.  so maybe only two 
backends would be needed: windows and CUPS?
