Hello, I'm sorry for cross-posting, but this issue is a really nasty one (and might come too late for some). If you use OpenType fonts in your TeX documents, don't update your Mac OS X unless you want to have some serious fun with printing ... http://reviews.cnet.com/8301-13727_7-20048314-263.html http://discussions.apple.com/thread.jspa?threadID=2792142 http://discussions.apple.com/thread.jspa?threadID=2791830 ... a workaround that worked for me (for PostScript printers only) was the following: I used http://localhost:631/help for help and ended up doing lpstat -p to get printer name and then lp -d some_very_weird_printer_name_ myfile.pdf to send the file to a PostScript printer. I wasn't sure whether it was an OS issue or LuaTeX issue (I updated both), but Florian on ntg-context mailing list posted the above links which most probably makes XeTeX users vulnerable as well.
