I haven't run into this one myself so I'm not sure this will work (but
simple enough to try).

There is one cups exec related boolean in the base policy:

 # semanage boolean --list | grep -i cup
You can try to enable it and see if it helps:

 # semanage boolean --modify --on cups_execmem

The semanage tool is in the policycoreutils-python package if you don't
have it installed.
