Rick, thanks for the reply.

At the moment I'm using NT4.x. In the future it could be nearly anything,
but I'm going to try to constrain it to nothing less than NT 4.x.

I'm using whatever the lpr command is that I got when I installed cygwin, I
don't see any options anywhere to change that. In fact I don't even see lpr
listed in any of the cygwin info on the web page, so I'm not at all sure
what it is.

'which lpr' shows /usr/bin/lpr
and "ls -l /usr/bin/lpr" shows lpr.exe to be 7680 bytes.

As to which printer, I'd like to (at a minimum) be able to print to the
NT-defined default printer, but better would be to figure out how lpr maps
into windows printers so I can tell it which printer to actually use.

As you may be able to tell I'm not real familiar with either Cygwin, or
NT., so the NT printing susbystem is largely a black hole to me.

Which lpr are you using, which OS (9x or NT/2K/XP), and are you trying to
print
to a locally attached or a network printer?
