Exodus Ride Shop review for Retail Barcode Labels

Being free is the only good thing. Why would a barcode app that generates barcodes generate duplicates? That should not be possible. More disappointing though is the print quality from Shopify is terrible. We use a Dymo label printer and these barcode look awful and some wont even scan. If you print the exact same barcode through the Dymo desktop app it's flawless. What is Shopify doing to cause the barcodes to loose such quality? A fix for this would great.
