Abstract
A system for preventing printing of duplicate barcodes includes a server (), a database (), a number of user computers (), and a printer (). The server includes: a print parameter initializing module () for initializing print parameters; an initial barcode number determining module () for searching for a highest barcode number that has been previously printed according to a preset print date and a part number, and for adding one to the highest barcode number in order to create an initial barcode number for the first printed barcode; and a barcode print controlling module () for managing operations of printing barcodes in order to prevent the printer from printing duplicate barcodes. The barcode print controlling module comprises a print controlling sub-module (), a print determining sub-module (), a print quantity checking sub-module (), and an impaired barcode printing sub-module (). A related method is also disclosed.
