[Samba] printer preferences not settable using samba print driver

[Mike F. Cavanaugh]

We're putting together a Linux-cups-samba print server for Windows 
clients. A dozen print drivers have been loaded and used successfully on 
the Windows clients from the samba server. But, one particular printer 
is causing trouble: a Xerox DC 2240. When a windows client tries to open 
the printer preferences, after connecting to the printer on the samba 
print server, a popup says "operation could not be completed".  Has 
anyone seen this behaviour before? I'm guessing that its somehow related 
to this printer's PPD file. When this printer's driver is loaded 
straight onto a windows client or from a Windows print server there is 
no problem.
