printings

[Patrizia Canton]

I am at this point now:
I am connected as root, today it works, yesterday it does not work (maybe
rebooting, I do not know).
BUT when I open the printer folder and try to assign the New driver
to the printer I endend with "It is impossible to obtain the specified
driver. The initial settings will be used".
So I cannot assign the driver.
I checked the directory permission of my /usr/local/samba/printers
the directory and the subdirectory is owned by root, and everybody can rwx
.
this is my smb.conf
