Hi Offshoreman,
I understand you have a Photosmart 7520 that you'd like to set up for 2 sided printing. I'd be happy to assist you with this!
To have something print 2-sided you'd want to click File and Print in the program and then you should see a screen similar to the one below where you can select 2-sided printing. If you want to make 2-sided a preset you can choose, just click where it says Default Settings and choose the Save option to make your own 2-sided preset.

Clik here to view.
Hope this helps, have a great day!!
