We recommend you use the 5567 templates in Avery Design & Print Online for Hanging File Tabs. It will automatically rotate the text to correctly label both sides of the tabs.
If you must use Word, please download the Word template at https://www.avery.com/templates/5567 so the tabs will be rotated correctly. The built-in Word template requires manipulation, so we have some special instructions.
Here's information on recommended printer settings.
