Each Excel sheet has its own print settings, because of this, it usually isn't possible to do this. However, if you are using a Brother machine that was released in 2003 and you are using Windows NT 4.0® or Windows 2000/XP, if all the printer settings within each Excel sheet are the same, you can print them as 1 job which means you can print two separate sheets in 2-sided(duplex) mode.
