LaserJet 1015 Manual Duplex Mode?

Hello!
I have the following problem - I've lost my original HP installation
CD-Rom and the newest drivers don't seem to have the Manual Duplex
Printing Mode at all. (Huh?)
Can you provide me with a solution for this problem? I really need the
Manual Duplex Printing Mode as some applications don't support e.g. even
or odd page printing and this isn't a good solution for single sheets
anyway.
