hi,
this is usually done by the printer-not excel. excel just send the data.
you must have a printer that duplexes. add that to your printer stack. when
you click the print icon, select the printer that duplexes. next click the
printers properties button (which is on the excel print dialog box next to
the select printer)
setting up to print both sides will be done here plus paper size, tray to
print from, color/BW, ect.

regards
