I'm temped to say "Run away! Run Away!". Printing can be hard to get
working sometimes. I don't have any magic solution, but I always start
by editing /etc/cups/cupsd.conf, set LogLevel to debug and restart the
cups daemon so it reloads it's config. Then try to print something and
look in /var/log/cups/error_log for lines that begin with E for error.
Google on the error messages (it may help but there's no guarantee).
Good luck.
