Print two-sided and multi-page layouts
To print on both sides of each sheet of paper:
Click File ◂ Print.
Go to the Page Setup tab of the Print window and choose an option from the Two-sided drop-down list. If the option is disabled, two-sided printing is not available for your printer.
Printers handle two-sided printing in different ways. It's a good idea to experiment with your printer to see how it works.
You can print more than one page of the document per side of paper too. Use the Pages per side option to do this.
The availability of these options may depend on the type of printer you have, as well as the application you are using. This option may not always be available.
