I'm new in this group, and I can't found the answer of my problem
anywhere. I read the HOWTO and explain something about it but I don't
find the solution.
Ok, the question is that I have SAMBA server with CUPS to share the
printer and home between 34 linux and windowsXP machines. I put the
drivers in a print$ share and all the people can install the driver only
clicking in connect...
The problem is that in some cases the printers default settings are
overwritten for someone (I don't know who) and all the people receive
this new parametres (for exemple not allow to print in both sides) and I
have to go to the printer admin change the properties and then uninstall
and install the printer.
I create a printer admin that is not root or administrator, I tried to
put the driver in read-only mode, but all fails.
I use gentoo (kernel 2.6.17), samba (3.0.22-r3), cups (cups-1.2.6),
openldap (2.3.30-r2).
An extract of my smb.conf (only the relevant):
