What is the difference between ordinary barcode machine and the qr code bar code printer _ printing equipment problems

qr code printer is a dedicated to print qr code bar code printer. Qr code printer and the difference between ordinary barcode printers, qr code printer to print way is given priority to with heat, carbon belt as a printer to print media, or direct the use of thermal paper, thus can continuous print qr code printer unattended. Qr code printer common type mainly has four kinds: stationary qr code printer, industrial-grade qr code printer, desktop and portable qr code printer qr code printer. Stationary qr code printed without PC support, can independently execute user programs, cast magnesium alloy structure, durable, light weight. Industrial-grade barcode printers, mainly for the industry to perform a larger area, sturdy die-cast metal shell. Strong real time connection, excellent compatibility. To adapt to the need of industrial field use, meet the requirements of industrial high quality print. Qr code printer is a kind of small size, small economic barcode printers, suitable for small and medium-sized enterprise mobile office. Small size, beautiful appearance. Portable qr code bar code printers, small size, lightweight, with functions of environmental interference. Characterized by using infrared or bluetooth technology as print data communication interface. Print the contents of the two dimensional barcode printer is normally for the enterprise brand identity, packaging label, bar code identification, envelopes, labels, serial number identification, clothing tags, etc. Industrial-grade quality, not limited by perform, can print 24 hours; Printing speed, the fastest can be up to 10 inches ( 24 cm) Per second, can print the serial number of the continuous, connect to the database to print; Printing material without limit, can print PET, coated paper, thermal paper sticker and synthetic materials such as PET, PVC and water to wash the cloth, etc. , not limited by the working environment; Using thermal transfer printing of text and graphics has scratch-resistant effect, the use of special carbon belt printing also can make the printing products are waterproof, anti-fouling, corrosion resistance, high temperature resistance and other characteristics; Label paper is several hundred meters long, generally can reach thousands to tens of thousands of small tag; Label printer for printing, easier to save and organize, the longest single tag can be reached more than 120 cm. Two dimensional barcode printers performance parameter accuracy depend on the qr code printer in the print head this important parts. Market on the surface of the printing precision is respectively: 200 dpi, 300 dpi, 600 dpi. The higher the accuracy, printed label and bar code, the more fine clear text. The user can according to the industry situation, select suitable for their own print label size requirements of product. Printing speed is compared with one of the strengths of stylus printer qr code printer. On market industrial-grade qr code printer speed can be up to 16 inches per second. For the same machine, the faster the speed, the lower the precision. Users in use, must adjust the machine, in order to perfect combination of speed and accuracy.
