Description of problem:
SELinux is preventing lpqd from 'read' accesses on the sock_file cups.sock.

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

If cree que de manera predeterminada, lpqd debería permitir acceso read sobre cups.sock sock_file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
allow this access for now by executing:
# ausearch -c 'lpqd' --raw | audit2allow -M my-lpqd
# semodule -X 300 -i my-lpqd.pp
