How can I efficiently print barcode labels for received PO items on Shopify POS?

Thank you. We looked at this but given the volume of labels, we use the Avery Label Sheets (8.5 x 11 with 30 labels per sheet). It would be quite expensive and time consuming to use the Dymo printer as it does single labels and we are often printing 100’s at a time. Shopify should have a way to chose multiple printers and associated Label Template.
