I need my current Shopify packing-list template updated so every time an order is printed it shows a scannable barcode that is identical to the order number—nothing more. For example, order HL1100 must appear as barcode HL1100. I have attached a sample mock-up to illustrate what I expect. Key points you should know before jumping in: • Placement is fixed: the barcode has to sit at the very top of the packing list, ahead of any other content. • Content is simple: no customer name, dates, or extras—just the pure order number encoded as a barcode. • Format is flexible: if Code 128, QR, or EAN-13 work equally well in Shopify’s Order Printer / Liquid environment, choose the most reliable one; I care only about fast, consistent scanning. - i can give you access to the Shopify store
