Abstract
A system for preventing printing of duplicate barcodes includes a server (1), a database (2), a number of user computers (3), and a printer (4). The server includes: a print parameter initializing module (22) for initializing print parameters; an initial barcode number determining module (23) 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 (24) 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 (241), a print determining sub-module (242), a print quantity checking sub-module (243), and an impaired barcode printing sub-module (244). A related method is also disclosed.
