Device and method for printing and comparing circulating label bar codes

Abstract

The invention provides a device and a method for printing and comparing circulating label bar codes, which belong to the technical field of bar code printing. The device for printing and comparing the circulating label bar codes is characterized by comprising a circulating label printing computer, wherein the circulating label printing computer is connected with a circulating label printer, a barcode reader and a concentrator through a serial port cable, a USB cable and a network cable respectively; the concentrator is connected with a pipelining server and a packing station through the network cable respectively; the circulating label printing computer is provided with a serial port blocking module, a global keyboard mouse hook module, a local area network data exchange module and a printing control module which are connected with one another in turn; and the printing control module is connected with the serial port blocking module. The device and the method have the advantages of being capable of determining the correctness of the printed bar codes and controlling the amount of products stacked on the packing station.

Description

Technical field [0001] The invention relates to a device and a method for comparing barcode printing of circulation labels, belonging to the technical field of barcode printing. Background technique [0002] The traditional circulation label barcode printing device and method have the following shortcomings: 1. The circulation label barcode is printed in a thermal manner. If a heating wire on the thermal print head is damaged, it will cause the defect of the barcode in this area, and the user can read the barcode. Cause a lot of trouble. 2. If the printing program is set incorrectly when setting the parameters, the printed barcode will be confused with other models, which will bring great hidden dangers to product management. 3. The unsynchronized printing of the circulation label and the packing station causes the accumulation of products, which is easy to be mixed during packing, resulting in defects. Summary of the invention [0003] The purpose of the present invention is to...
