Two sides printing HP Photo Smart C4280 OS X Lion

Hi folks!

I am just trying to find the HP driver to have my HP Photo Smart C4280 printer to allow the feature Duplex Printing. After doing some research, I just could find the link for Snow Leopard.

Did HP forget to release a solution for OS X Lion?

Thanks.
