Jason,
I know GSPrint can work with Windows printers.  It works fine if you only
want to use the windows default printer.  I couldn't, however, get it to
work correctly with the -printer and -query options (well, the -printer
part is mostly shell quoting issues, but the -query just doesn't seem to
work, somehow).  Any insight will be appreciated.  I'm attaching the
script that I currently have.

A question about your script: you're using the '-_' option, which doesn't
seem to be documented on the GSPrint page (
http://www.cs.wisc.edu/~ghost/gsview/gsprint.htm ).  What exactly does it
do?

I also found this thread extremely interesting and relevant:
http://sources.redhat.com/ml/cygwin/2000-11/msg01570.html
a2ps seems like the perfect solution for lp/lpr.  Is it ever going to
become a cygwin package (
http://www.cygwin.com/ml/cygwin/2001-08/msg01240.html )?

Thanks,
	Igor
