Duplex printing in Karmic doesn't work at all!!! In OpenOffice I even can't choose to print as duplex (screenshot added). But the duplexer is marked as installed (screenshot added).
In evince it's the same. In the HPLIP Device Manager the Duplexer is marked as installed as well (screenshot added as well).
