Is there some reason you do not want a CUPS printer?  You should still
be able to run lpr and family with a CUPS printer.  Is the CUPS daemon
running?  Can you browse http://localhost:631/ ?  Is 127.0.0.1 aliased
to localhost in /etc/hosts?   I think there was someone with a similar
problem and the cause was localhost was aliased to their network IP
and iptables was blocking access to port 631.  If you really want to
undo this, then I'm not sure how.  You can always remove then add, I
suppose.
