[cups.general] default options not shown ipp client

[Florian Doersch]

Hi,
I have following problem:

I created 2 printers:

Normal
Duplex

for the second one duplex is marked. If I print from an ipp-client, duplex 
works, but: If I open the printer-options, duplex's unchecked. I tried also 
different ipp-client (MacOS X) but theres the same problem.

What do I have to change on the clientside (or serverside) so the 
remote-client see the predefined options in his printer-dialog/program?

Thank you very much.
