The filter is running UID lpd GID lpd.  Check the UID/GID on the
/usr/local/libexec/filters file.

You can do some debugging by having the filter send messages to STDOUT
so you can see stuff such as the permissions on the executable.

Fix:  You need to make scripts executable AND readable...

chmod -R a+rx /usr/local/libexec/filters
