The permissions are still set wrong in 6.10 - I just downloaded and installed it, and the printing worked fine on the live CD but not on the hd install.
I ran into this problem but it was only a permissions issue with lp0. Took me 1/2 hour of sifting through this and other threads to track it down. This thread is a year old - why the heck is something as major as wrong permissions for lp0 still hanging around? -- cupsys does not automatically detect parallel printer https://launchpad.net/bugs/29050 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
