hi
this is a printer function not an excel function. if your printer can print
duplex(two sided) then you will have to set this up with the printer.
techically all excel does is send the data. i don't have 07 but in previous
versions, there was an options button on page setup that displayed the
default printer options. you can set up duplex printing there.
if your printer can't do duplex printing then you'll have to do the old
fashion way. print every odd page, then flip the paper over and print every
even page.
see this sight on how to do that.
