samba - Sep 2005 - Guest user mapped account rights not being set correctly

Hi,
 
    I wanted to allow unknown(guest users)  users to print. I have used
"guest ok = yes", "map to guest = bad password" and
"guest account guestuser" where guestuser is a windows domain user.
The reason for
using this being the windows user can modify the rights that would be
given to the guest account by changing the rights to guestuser in the
security tab of printer properties. However, the guest user is able to
print only when the user "everyone" is given print access in the
printer
-> security settings. He is not able to print when "everyone" is
removed
and "guestuser" is given print access although I could see from the
logs
the mapping to guestuser is happening correctly.I have also included my
smb.conf. Please let me know if I am doing something wrong.
 
smb.conf

winbind enum users = yes

force user = root

[printers]
