Hi Kendra, I suspect this functionality would come down to the "Print Settings", and your printer may or may not support it.
You can definitely spend time exploring that button (near the top of the screen) but to be honest, it'll be much easier just to duplicate the design in Photoshop, so there's two on the page, then print it as normal.
If you need help with doing that, can you show me a screenshot from Photoshop, showing me the design and your layers panel?
