SELinux is preventing /usr/libexec/colord from 'ioctl' accesses on the chr_file /dev/parport0.

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

If you believe that colord should be allowed ioctl access on the parport0 chr_file 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 colord /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
