Direct thermal label printers (like Dymo) are able to print PDF's, and when they do they assign each page of the PDF to a single label. With the appropriate template selected, Super Address Labels inserts a page break between each label so that one page of the PDF represents one of the labels in the batch.
The application contains some built-in templates for single label printers (like Dymo). If the one you use is not present, you can still create labels for your printer by simply entering the width and height of your labels in inches, millimeters, or centimeters.
Super Address Labels is an application for Shopify that enables merchants to print addresses and other data from their orders onto label sheet templates made by Avery, Dymo, and other manufacturers, using a laser/inkjet or direct thermal printer.
