The principle of a barcode printer can be divided into several parts: 1, bar code printer hot stamping principle 2, bar code printer label drive technology principle 3, bar code printer ribbon drive technology principle (hot transfer mode) Bar code printer principle analysis: 1, bar code printer hot stamping principle There are two main types of hot stamping for bar code printers. One is the thermal discoloration method of thermal paper, which is also known as the thermal method; the other is the transfer of ink ribbon, which is also known as thermal transfer. In the thermal printing mode, the bar code printer works by printing hot hair, and the thermal label media is discolored after being heated at the hot spot of the bar code printer head to display the content to be printed. Labels that use thermal print media will gradually fade under daylight and have a short shelf life (usually no more than 6 months). Many applications require long-term label storage, which requires printing using the thermal transfer principle (currently Ricoh has introduced a special thermal paper that can be stored for six years). In the thermal transfer printing mode, the bar code printer works by printing onto the label printing medium using a thermal transfer ribbon as a medium. The computer-controlled bar code printer prints the hair heat, and the toner coating of the thermal transfer ribbon is melted and transferred to the label printing medium under the action of the thermal heat of the printed hair and the pressure of the print head, showing the pattern to be printed and Text. Labels printed using thermal transfer can be stored for longer depending on the material of the label and the material used for the ribbon. For example, PET durable labels printed on resin-based ribbons can usually be stored for 3-5 years or even longer. time. 2, bar code printer label transmission technology principle Barcode printer label drive currently uses two methods, one is the way the print head is flat, and the other is the way the print head is suspended. The flat press method generally only uses the front roller to drive the paper feed (some wide) The bar code machine will also drive the front and rear roller shafts at the same time. The suspension pressure method adopts the driving mode of the front and rear double roller shafts. Therefore, the flat pressure method, the print head, the label and the front roller shaft are in a compact state, and the suspension pressure is suspended. In this way, the print head, the label, and the front roller can be in an incompletely pressed state. The paper feeding mechanism of the label is driven by the same motor whether it is flat pressing or hanging. If it is a double roller drive, it is generally driven by a belt driven double roller. In the principle of bar code printer, this one is the most reliable bar code. A standard for printer durability, the durable bar code printer drive belt gears are made of metal to ensure the life of the transmission structure in the high-speed operation of the bar code machine, such as the Zebra 110XiIII. Barcode printer accessory drives, such as bar code printer rewinders, bar code printer strippers, are also drive motors that use paper feed mechanisms. 3, bar code printer ribbon drive technology principle (when thermal transfer method) Barcode Printer Ribbon Drives are currently available in two ways, one with the same drive motor as the label feed mechanism and one with a separate motor drive (common in the suspension press). When the barcode printer ribbon drive and the label feed mechanism use a set of drive motors, the energy is transmitted through the belt belt. There are generally 2 ribbon shafts. The front ribbon shaft is the drive shaft and the rear ribbon shaft. It is a driven shaft. The drive shaft is driven by a motor. It moves synchronously with the printing of the label paper. The driven shaft relies on a damping piece or a damping spring to make the ribbon straight and flat. When the bar code printer ribbon drive is driven by a separate motor, the front and rear dual motors are generally used to control the action of the ribbon. The biggest advantage of this method is that the ribbon saving function of barcode printing can be realized. 4, bar code printer sensor automatic detection principle Barcode printer sensor automatic detection mainly includes three parts: 1 label positioning sensor Currently, the tag positioning sensor can detect the interval label, the black label, and the hole label. 2 ribbon detection sensor At present, the ribbon sensor can detect whether the ribbon is installed in the thermal transfer mode. Is the ribbon exhausted? 3 print head opening and closing detection sensor At present, the print head opening and closing detection sensor can detect whether the print head is properly closed. 5, bar code printer DSP data processing principle Bar code printer DSP data processing is a way of data conversion, that is, the computer sends graphics commands to the bar code machine, and the bar code machine drives the print head thermal element to print related content through data storage and data processing.
