File Permissions
For security reasons, CUPS will only run filters and backends that are  
owned by root and do not have world write permissions. The recommended  
permissions for filters and backends are 0555 - read and execute but  
no write. Backends that must run as root should use permissions of  
0500 - read and execute by root, no access for other users. Write  
permissions can be enabled for the root user only.
