The set-user-ID-on-execution

Hi:

I made a script (for tcsh shell) which add a printer to the system
(made directories, files, security and made some validations) but
need root access to accomplish this task.

my solution was to setuid the scripts been root

# chown root:admin-hmo *.tcsh
# chmod u=swrx,g=rx,o= *.tcsh
# ls -l
total 4
-rwsr-x---  1 root  admin-hmo  2024 Aug  3 04:07 impresora.tcsh
-rwsr-x---  1 root  admin-hmo   275 Jul 30 02:26 seguridad.tcsh

The first line of the script is #!/bin/tcsh -fb

But when I run the script been other user I had problem with
the permissions

> impresora.tcsh oc81p8707 p1ct203 psct203 raw
mkdir: /var/spool/lpd/oc81p8707: Permission denied
touch: /var/spool/lpd/oc81p8707/filter-errors: No such file or directory
touch: /var/spool/lpd/oc81p8707/accounting-file: No such file or
directory
/var/spool/lpd/oc81p8707/minfree: No such file or directory.

did I miss something?
