To print a document, select File > Print... or press <Ctrl><P> on the keyboard. This opens an operating system-specific standard print dialog.

Clicking Print (or OK) prints the contents of the active display in the Graphics window. The contents of this dialog are not documented further. Please refer to your operating system documentation for details of using this dialog.
This action is only available if a simulation is visible and a document (visualization scene or plot display) is visible in the Graphics window (it does not have to have the focus).
