How to run CUPS back-end as root

[Ido Levy]

I am running RHEL 5.3 with CUPS version 1.3.7-8.el5_3.6.

The CUPS daemon, cupsd process, is running as root:
   # ps -ef | grep -i cupsd
   root     30805     1  0 16:16 ?        00:00:01 cupsd
but the back-end I have written is running as the lp user.

How can I set the back-end to run as root ?

Thanks

Ido
