“My barcode will not scan” is the warehouse version of a 404. Use a native barcode (not a phone photo), leave a quiet zone, print at 203 or 300 DPI on the actual stock size. Open the free label maker to do it now.
Good to know: A pretty Canva barcode image is often too soft for 203 DPI thermal. Rebuild native here.
