If your printer is capable of printing double-sided (or duplex,
as it is sometimes called), then you can usually choose that
option by clicking on File | Print | Properties.

If your printer cannot print double-sided, then you can print the
odd pages, put the odd pages back into the printer's input paper
tray, and then print the even pages. Depending on whether your
printer stacks printed output face-up or face-down and your
printer's input paper path, you may need to flip the odd pages
over before reinserting them into the printer and/or print the
even pages in reverse order.

I have a basic word doc. that is about 60 pages single sided. What is the
set up to print that double sided, or 30 pages? Thanks.
