Problem description: Unscannable 2D barcodes


We have been providing box content via 2D barcodes for a long time now and have only recently been told that some of our FBA shipment boxes have Unscannable 2D labels on them.

From speaking to Amazon we have been told that our thermal printers 200 DPI isn’t good enough and needs to be a minimum of 600 DPI even though we have sent 1000’s of boxes with our current printer and not had any issues.

What thermal printers are people using?


can you not just adjust the dpi in your printer settings ?


Unfortunately not, the maximum DPI capability is 200
