Duplexing all

[Sergei]

Is there a way to change them all the worksheets in a book
to "print on both sides"(duplex)without doing each one 1
at a time? I tried grouping and page setup, it works for
everything but duplexing!

Couldn't you just change the printer's properties so that it prints duplex?
