How do you print two-sided in In Design when some sections have an odd number of pages?

Question

I'm new to In Design, and I'm trying to do something that seems pretty basic and having trouble figuring out how to do it, and I haven't found anything in the Adobe Forum or online that addresses this situation.
I am working on a document that is broken into sections, with page numbering starting on Page 1 for each section.  I have mirror image layouts for the odd and even master pages - for example, the page number is on the left side on even pages and on the right side for odd pages, as you might generally expect to see on a two-sided printout, where in a book or a binder, the even pages are on the left and the odd pages are on the right.
I'm printing the document from my computer onto a printer that supports two-sided printing.  I don't see any options in the File / Print window for two sided printing, so I set this option on the printer itself using the [Setup...] button at the bottom of the window.  This works - I am getting the printout on both sides of the sheets of paper.
At the moment, the first section is 3 pages (two spreads, one with the first page, and one with the other two).  The next section starts with page number 1 on the third spread (one page) and then continues two pages per spread - all as expected.
Here's the problem - the first page of the second section is printing on the back of the last sheet of first section, rather than starting on a new front-facing sheet - so when I put this in a binder, the odd pages are on the left and the even pages on the right.  Every time I hit the end of another section with an odd number of pages, it flips around again.
There's a manual workaround I found - scan through the document and add a blank page to the end of every section that has an odd number of pages (and check "Print Blank Pages).  But I'd have to do this every time I print as I'm adding new pages, and add/delete blank pages as the number in each section changes.
I can't believe that In Design doesn't provide a way to get this to work properly, as I'm sure many people have had this same situation, and I'm hoping that it's some simple thing that I just haven't been able to figure out...
HELP!!! (thanks!  B^)

Well, MS Word does something like this automatically - if you tell it to start a new section on an odd page, and if the section before it ends on an odd page, it will "skip" the even page number in between - and when it prints, it automatically spits out a blank page in between them, so that on a two-sided printer, the odd pages all print on the front of the paper (which is the right-facing sheet when they are put in a binder or book).
InDesign shows the pages like this on the spreads (odd page numbers always on the right), so it is aware of the desired orientation, and I'd think it would provide a mechanism to ensure that they print out this way as well...
