Unable to print my documents two sided on iP7260

[tel851]

The option to select two sided printing is greyed out on my iMac for my iP7260, how can I change this?

Hi tel851,

What version of OS X is installed on your Mac?

To determine this, please click the Apple in the upper left hand corner and then About This Mac.  The version of OS X installed will be listed in the window that appears.
