Samba/Cups - windows client does not have duplex and other options

[Brett Carruthers]

Hi,

I am attemping to migrate our office printer server from windows over to one 
of our linux servers. I am facing a problem of the windows clients not 
seeing all of the available driver options (duplex printing etc) - the 
picture below explains my issue;

The left hand side is a printer off a windows server and the right hand side 
is the printer created in CUPS i am trying to get working. The one on the 
right is missing the duplex printing option and another tab 'Destination'.

Anyone have any suggestions? The client printer driver is the same for both 
printers and these are both on the same latop.

Thanks,
Brett
