About the Mastiff: Print Barcode Labels

Mastiff is a barcode generator and label printing app built for retail stores that need reliable product labels. Unlike standard barcode apps that just generate and print, this one scan-checks every label before it prints to verify each barcode scans correctly as the product it belongs to. You'll see the decoded value next to what you intended, so bad barcodes never make it to paper. The app generates UPC, EAN-13, and Code 128 barcodes with valid check digits and blocks duplicates across your entire catalog. Print price tags and product labels that include title, price, SKU, and barcode on one label. It works with Dymo, Brother, Zebra, and Avery label printers with presets for exact sizing, plus custom sizes and a calibration page. You can also print labels from purchase order CSV files with column mapping and quantities filled. Previews, test prints, and reprints don't count toward your printed label total. Email support is answered the same day.
