Yes. To reprint, open the route, click Print, and enable Packing slips and/or Packing labels. You can send the batch to a printer again or save a fresh PDF. Reprinting uses your current template settings — if you change variables or sizes in Settings → Packing Slips & Labels, the new output will reflect those changes.
If the route has been archived from your EasyRoutes account, restore it before printing. This reprint flow works the same in both EasyRoutes for Shopify and EasyRoutes for Web.
