How to set even pages to be blank

[Mitja B]

I have generated a PDF with Prawn. I would like to add every second (even) blank page.

So the PDF can be printed onesided ;)

This is how I solve it:

  

      # ----- add blank pages

      (1..page_count).each do |p|

        if go_to_page(p+(p-1))

            start_new_page

        end

      end
