I dont think Shopify has implemented this yet despite a lot of requests for this functionality. Best to contact the helpdesk to check and if not, be added to the list of people asking for this. Here is a thread I found about this... community.shopify.com/c/shopify-design/can-we-print-retail-barcode-labels-directly-from-purchase-orders/td-p/2141886
No sorry - they seem to be in short supply. Would recommend the Bixolon which is pretty much the same thing for $350 cheaper. tillman.co.nz/collections/label-printers/products/bixolon-xd3-40-label-printer-for-courier-and-barcode-labels
