Summary0016066: SELinux is preventing /usr/lib/cups/backend/ecblp from 'open' accesses on the fifo_file /run/ecblp0.
DescriptionDescription of problem:
Try to print
SELinux is preventing /usr/lib/cups/backend/ecblp from 'open' accesses on the fifo_file /run/ecblp0.

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

If you believe that ecblp should be allowed open access on the ecblp0 fifo_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'ecblp' --raw | audit2allow -M my-ecblp
# semodule -i my-ecblp.pp
