Deploy printer with single sided defaults

Hi,

We are trying to deploy Xerox WorkCentre printers.  Deploying is no problem but it always deploys the Xerox Print drive to double sided rather than single sided and then we have to save it.

How can I set the driver to single sided default on the deployment?  Setting the defaults on the sever first doesn't keep maintain the single sided for the client, it goes back to double sides.

Thanks
