Not able to open print setup in my mac. I use OS X EI Captain 10.11.1 I am not able to open print setup.
When I Open Print Queue, i get the following screen

I am not even able to given double sided printout.

Please help me out

Basically, I want to give back to back printout. But I am not getting that option at all.. In print setup, when choose Layout, the "two sided" dropdown is greyed out as shown below.
It's not entirely clear from your question, but I think you're just looking in the wrong place. The Printers &amp; Scanners control panel is a 'set &amp; forget' control, one you really only need if you add a new printer.

You deal with the regular task of adjusting printer defaults for a given print job from the Print menu in your current application - this example from Safari
