Before you print your item tags, make sure that you have turned off all pop-up blockers before you print. NOTE : You may have to do this more than once. FYI : If you aren't sure how to turn off all your browser's pop-up blockers, hold down the CTRL key when you click on the print tags link. This should temporarily disable all pop-up blockers.
Once you have your browser's pop-up blockers, you will see a screen that shows you all your items (much like a print preview screen). You should see 6 item tags per page. And, from there, just print away!
