Printronix owes a lot to Barcodes. In fact, our Chairman, Bob Kleist was an early pioneer in the technology, helping to develop and test many early barcode systems in the burgeoning period prior to founding Printronix in the 70's. The first line matrix barcode application was in paper mills, where Printronix printers could operate in a hostile environment and print large barcode labels, large enough for a fork lift operator to read from a distance. This was quickly followed by barcode applications in other manufacturing environments, particularly automotive and retail distribution. Many of Printronix customers power their businesses with barcodes. Our Online Data Validation (ODV) option for our flagship T5000r thermal barcode printer, for example, helps businesses eliminate the costs associated with bad bar codes by scanning a barcode as it is printed, striking through bad labels and automatically printing new ones.
