SELinux is preventing lpqd from 'sendto' accesses on the unix_dgram_socket /var/lib/samba/private/msg.sock/2012.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that lpqd should be allowed sendto access on the 2012 unix_dgram_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'lpqd' --raw | audit2allow -M my-lpqd
# semodule -X 300 -i my-lpqd.pp
