Well it almost, but doesn't work.
If I DON'T modify the rules I get in response to "ls -l /dev/usb"

crw-rw---- 1 root lp 180, 1 Nov 23 16:59 lp0
crw-rw---- 1 root lp 180, 0 Nov 23 16:59 lp1

If I add my two rules I get this:

crw-rw---- 1 root lp 21, 1 Nov 23 16:59 lp0
crw-rw---- 1 root lp 21, 0 Nov 23 16:59 lp1

The latter DOESN'T work, nothing prints.
The former does print.

I added GROUP="lp" to the rules and nothing changed.
So I've missed something. Anybody have any ideas?
