Test checklist

  • Duplicate the Shopify Order Printer template before editing the live one.
  • Preview with the regular order.
  • Scan the printed code with the same scanner or phone workflow staff will use.
  • Print or save one test preview before using the template in production.

Common failure

  • The barcode renders blank because the selected SKU, variant barcode, or tracking value is empty.
  • The snippet is pasted outside the line item loop, so line item fields are not available.
  • The merchant uses order_number when warehouse staff expect the visible order name, such as #1048.
