Comment 26 for bug 657357

Charles, can you start system-config-printer, right-click your printer, choose Properties, click the Change button for make and model and in the selection for the driver choose the hpijs one? Then you should be able to choose duplex in all printing dialogs and your printout will come out double-sided.

jpka, note that there is only a Duplex option for your printer if you ude the SpliX driver. If needed, change to SpliX with system-config-printer.
