Printing Duplex
For double-sided (duplex) printing open the printer driver Plug-in by
clicking on [File] -> [Print] in your application. By default the Basic panel is
shown when opening the Plug-in. Here you can use the quick print buttons
to easily create the desired output. Just click on the button [Print duplex] in
the lower middle of the panel.
The Plug-in is closed, and the main print dialog is shown again. Click [Print]
to start printing.
