If your customer's address as captured by Shopify is not in a correct or desired format, it can be edited before printing.
Hover your mouse cursor over any individual label in the preview and click "Edit shipping address". To edit the shipping address of every order currently selected, click "Bulk edit all addresses".
If you’ve edited an address, the next time your mouse cursor hovers over the label a "Restore shipping address" button will be present. This resets the content of the label to the original address from the order in Shopify.
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.
