Finish setup and try to print a testpage: selinux blocks ipp-printing
SELinux is preventing brcupsconfig3 from using the 'execmem' accesses on a process.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow cups to execmem
Then you must tell SELinux about this by enabling the 'cups_execmem' boolean.
You can read 'None' man page for more details.
Do
setsebool -P cups_execmem 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that brcupsconfig3 should be allowed execmem access on processes labeled cupsd_t 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:
# grep brcupsconfig3 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
