This is an older post from a while back. The problem seems to have resurfaced. On my machine after a reboot, I have:crw-rw---- 1 root lp 6, 0 2006-10-29 20:03 /dev/lp0 I can't use the printer until I change it to lp:lp or chmod 777. I'm guessing this is a udev problem, but how do I fix it for good?
Have you tried adding yourself to the lp group?
