Here are the steps to set up a print server (CUPS) on a container using Debian.

• Create the container and do your initial setup.
• apt-get cupsys cupsys-bsd foomatic-db cupsomatic-ppd (etc)
• Return to the HN and do the following:

vzctl set <veid> --devnodes lp0:rw

• If you configured parport, etc, as modules, you'll have to do the following:

cat << _EOF_ >> /etc/modules

<code>parport

parport_pc

lp

_EOF_

• Return to the container and configure your printer in CUPS.
