Vicky, I don't think it's really upside down.  Think about how it would look
if it had 3-holes punched and was bound up.  The top of each page should be
along the edge with the holes.  But in that fashion, if you flip the page, it
does appear upside down from page to page.

I don't know of a setting in Excel to flip that around.  Depending on the
printer, their might be one in the printer setup to reverse it.  Neither of
my printers here have such a setting.
