***** 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

Could you try it with the latest selinux-policy build?
Thanks,
