You probably need to use "/dev/parport0" instead of "/dev/lp0".

You will also need your permissions to look like this:

address@hidden:~$ ls -al /dev/lp0 /dev/parport0
crw-rw----    1 root     lp         6,   0 Jun 13  2001 /dev/lp0
crw-rw-rw-    1 root     root      99,   0 Oct 22  2002 /dev/parport0

so that you won't have to run as root.
