samba - Jun 2006 - Samba 3: Changing printer settings cause reinstallation of printer driver

Dear folks,

I lately updated our PDF-Server (printer provided by Samba which converts 
the postscript to a PDF and sends it back via email) from 2.2.8 to 3.0.20.
I installed the printer driver on the samba server as described in the 
samba how-to and the server delivered the printer driver with the default 
settings just fine.

Now I have the problem that I want to change the default printer settings 
on the server so that he can hand it through to the clients. But every 
time I do a change for example from "portrait" to
"landscape" the
printserver (samba) doesn't deliver the printer driver anymore. I always 
receive the error message that you get, when no driver is installed on the 
printer server at all. Here again, I followed the samba how-to for 
changing the default print options as described in "samba how-to: 19.7.2 
Setting Device Modes on New Printers".

Does anybody have the same problem or an idea to solve it?

cheers

Lynn
