Thanks to their acquisition of RJS Verifiers, Printronix offer an in-line barcode verification system for use with their (and other brands) thermal printers. Printronix Online Data Verification (ODV) is the most sophisticated system currently available and verifies the barcodes to the appropriate ANSII specification. The ODV system can be configured to not only inspect every barcode that is printed, but also save the data in common database formats. This is really useful for quality audits or for being able to prove compliance with customer barcode mandates.
