How to print?

My printer is HP LaserJet 5M. It does surport back to back printing(print both side of the paper).
My question is how to let the printer know I want to print on both side?
I use command lpr to print, But I could't find this option in the lpr man page.

Thanks !

You should install ifhp.  You can find this at
http://www.astart.com/LPRng.html.  In order to get this to work you will also need to have the lprng spooler installed.  This is a nicer spooler than the stock lpr spooler (the one you have) which is often the default spooler in many distributions.

You should also read the FAQ on the site which discusses duplex printing:
