Quick answer
Show Shopify order notes on a packing slip for Shopify Order Printer
Use the line item properties generator with order note output enabled, then place the order-level note outside the item loop. Start in a duplicate Shopify Order Printer template, paste the Liquid in the right placement area, and preview with real orders before saving.
- Confirm whether the message appears as the order note, a note attribute, or a line item property on a real order.
- Paste order-level note output outside the line item loop, usually near shipping details or the footer.
- Use line item properties only when the note belongs to a specific product.
