How to print different file folder labels on one sheet at once

Templates assume repetition of some sort that is reproducible. For a template to use different pieces, you are better off using a layout program. Word is not a layout program. Adobe InDesign is a layout program.

You are better off testing on a blank sheet of paper ensuring the layout is what you want, and then verify it lines up with the template label paper next. If you need different sizes, get one standard size sheet of paper label sheet which you can then cut to size with a paper cutter.

You can still download Word label templates from Avery, and Word itself has a lot of Avery templates already built into it.

Word > Mailings > Labels > Label Options > Label Products (choose the vendor) > Product Number (choose the product number for the label sheets you have). Ignore the "Number of Labels" selection and don't type anything in the Delivery Address box. After selecting your product number, just click OK and you will get a sheet of formatted, blank labels where you can type whatever you want for each label, format as desired, etc. and then print them. I do this all the time for file folder labels.
