Printing final return duplexed

When I try to print my return using duplex, the sheets don't print properly.  Example, when you read a book, they pages are all oriented the same way.  When I print my return in Turbo Tax, the second (duplexed side) prints upside down.  I have changed the information both ways for duplex printing (print on long edge or short edge), but no matter what, the form prints so that I read the front page, then have to flip up the next page because it is upside down. How to fix this?
