Avery graciously provides a label formatting software that relies on Word (among others) to generate a label file with various possible formats. No need to be a computer to use is relatively simple and there are many possibilities. The easiest way is to start from a Excel file with the different addresses. You can edit personal address labels by adding a photo, for example. Etc ..... as to label it ourselves, it is a product without concern that I use different formats for years; in short it is an excellent price / quality ratio
