I poked around at this some more, and found something interesting. If the "last_rule" option is added to the rule on line 37, the device node gets created with the correct group. This leads me to believe that some other rule later in the chain is overwriting the GROUP, however I was unable to find such a rule.
The attached patch causes the device node to be created with the correct group. ** Attachment added: "seems to fix the bug" http://librarian.launchpad.net/5726321/udev-lp.patch -- Permissions on /dev/usblp* don't agree with cupsys https://launchpad.net/bugs/76077 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
