I want to use the VpeSetDevDuplex property to print on both sides of the paper. When I set the property value to 3 it still prints on 2 papers instead of one.
I'm using Vpe 3.50 and want to print to a Kyocera FS-9120.
Does anyone know if this works on this printer? I tried it also on a HP8100 and this also didn't work.
