[cups] Setup cups and Brother HL-4150CDN on FreeBSD 10

Mon Jun 9 13:56:23 PDT 2014

The error message
E [08/Jun/2014:17:37:53 +0200] [Client 15] Invalid peer credentials  
for "root" - got 8, expected 0!
states that the efective user id cupsd is runnin under is 8, which  
certainly is not root.
Make sure your cupsd is running as root.
(see scheduler/auth.c in your sources directory tree).
