How to Enable Duplex Printing on Linux Printer Properties

[Izaak]

I need to set up the printer so it will print on both sides but when I go into System/Administration/Printing and click on the Printer tab and click properties, nothing happens. Am I supposed to re-configure it using the terminal? What should I do?

I am running Fedora 11
(I'm not the one who configured the printer)

What kind of printer is it exactly?

If you're printing from the command line the way to tell it to do duplex printing is
lpr -Zduplex filetorprint.pdf

I think most programs (e.g., firefox, acrobat reader) let you edit the printing command they use, so just make sure the -Zduplex option is in there.
