Duplex printing - how to pad with blank pages

Hello All,

My appendix pages are arranged as follows:

The Appendix title (e.g., Appendix A. Application Form) appears
on a page by itself, and is followed by one or more pages.

When printing double-sided, the form will be printed on the
other side of the page with "Appendix A". How can I automatically
add a blank page after "Appendix A" to prevent this?
