If you want to print the two pages before the section break at
the end of the 2nd page, then enter either s1 or p1s1-p2s1 in the
page range box in the File-Print dialog. (that's s-One or
p-One-s-One-p-Two-s-One)

If you want to print the two pages after the section break at the
end of the 2nd page, then enter p1s2-p2s2 in the page range box
in the File-Print dialog.

The first two pages of my Word document are not numbered. At the end of the
2nd page I have inserted a Next Page Section Break because I need to start
numbering my document, starting with 1 in the footer to begin on the 3rd
page. When I go to print and select pages 1-2 to print double sided I also
get pages 3 and 4. I believe this is happening because I have started my
numbering to begin on page 3. Is there any way to stop this from happening?
