Make every even-numbered page blank. (Insert new blank pages in between your pre-existing content-bearing pages.)
Also, after adding the blank pages, I suggest you print from a PDF rather than from InDesign. To do this export the InDesign document using the Adobe PDF presets and select High Quality Print, in the subsequent Acrobat dialogue boxes select print individual pages. You can select which range of pages you want and the number of copies you want printed.
