Printing under OS X

[Tim McNamara]

I'm running Emacs under X11 in Mac OS X and have a printing question
that I couldn't resolve looking at the documentation.  OS X now uses
CUPS.  I can print a file on my HP LaserJet 1012 using File > Print
Buffer.  I can't print a TeX file from within tex-mode using any of
the options Command > Print.  Obviously I'm doing something wrong; I
can't figure out what.

Thanks!
