Full Discussion: CUPS setup / dev/lp0 perms. ... Slow printing.
Operating Systems Linux Slackware CUPS setup / dev/lp0 perms. ... Slow printing. Post 302278627 by agentrnge on Tuesday 20th of January 2009 06:13:22 PM

Upon each bootup /dev/lp0 is getting created with permissions to allow root and group lp rw access.

The printer shows unavailable. print jobs error out saying "unable to write to /dev/lp0"

cupsd is running as root
parallel is running as lp

As soon as I add +rw to all users it is fine. This does not feel like the correct "solution".
