If your printer has a special "duplex" option, you can use it to automatically print double-sided. However for most printers, you need to:
1) Print the "odd-numbered" pages first
2) Feed the printed pages back into the printer
3) Print the "even-numbered" pages
If your printer prints pages face up, you may need to tell your printer to reverse the order when printing the even-numbered pages.
