System and method for preventing printing of duplicate barcodes

A system for preventing printing of duplicate barcodes, the system comprising a server, a database, one or more user computers and a printer, the server being interconnected with the database, said user computers and the printer through a means of communication, wherein the server comprises:

• a basic data maintaining module for maintaining all kinds of basic print data by way of adding, modifying, searching and deleting the basic print data;
• a print parameter initializing module for setting print parameters;
• an initial barcode number determining module for searching for a highest barcode number that has been previously printed according to a print date and a part number on which the barcodes to be printed are attached, and for adding one to the highest barcode number in order to create an initial barcode number for the first printed barcode when the printer starts printing;
• 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 comprising:
• a print controlling sub-module for adding one to a current barcode number and to a current print quantity after each barcode has been printed;
• a print determining sub-module for determining whether a user has canceled printing;
• a print quantity checking sub-module for checking whether the current print quantity is equal to or greater than a preset print total;
• and
• an impaired barcode printing sub-module for receiving user-input instructions about whether to reprint one or more impaired barcodes, determining an initial barcode number for said impaired barcodes that need to be reprinted and a print total, and instructing the printer to start reprinting said impaired barcodes continuously.
