... En tiedä miksi sinulla tuo ryhmä on root eikä lp, niinkuin defaulttina pitäisi olla, voit yrittää vaihtaa ryhmän lp:ksi komennolla sudo chgrp lp /dev/lp0
...
Siis
$ ls -l /dev/lp0
crw-rw---- 1 root root 6, 0 2007-03-06 17:23 /dev/lp0
$ sudo chgrp lp /dev/lp0
$ ls -l /dev/lp0
crw-rw---- 1 root lp 6, 0 2007-03-06 17:23 /dev/lp0
reboot ja taas on
$ ls -l /dev/lp0
crw-rw---- 1 root root 6, 0 2007-03-06 17:23 /dev/lp0
Miten korjataan?

Tässä vielä 40-permissions.rules- jos siitä olisi apua
