InDesign printing issue

Hi, I am trying to print a very simple book, that is just comprised of normal letter sized paper that will be collated together. So, just one InDesign page per printed page, not like a bound book with two pages of the book per one printed page, and the pages are printed double sided. When I print, the pages come out in random order and it never prints all of the pages. It is very strange. Is there a special InDesign print setting that I am ignoring? Does anyone know why it wouldn't recognize certain pages to print out? At first I was just printing one side, but it is when I started making it double sided that I had issues with it not printing all of the pages.


Also, I am printing to a Sharp MX-5001N PCL6 if that makes any difference. I just set it to print double sided, landscape and to print blank pages. Not sure what other settings would affect it.

Any help would be appreciated. Thank you!
