Introduction to bluetooth printer

Panel Printer China is the application of bluetooth technology on the printer, get rid of the Panel Mount Thermal Printer connection, the inconvenience of wirelessly print, can reduce the unpleasant cables on the desktop, and the printer can be far away from the host move, put in the room is suitable for the position.

Bluetooth is a low cost and high capacity short-range wireless communication specification. A bluetooth laptop is a laptop with bluetooth wireless communication function. The name bluetooth is still a legend. In the 10th century, when the vikings of northern Europe were fighting for supremacy, the king of Denmark stepped forward. Through communication, the vassals resolved their differences and became friends. Because the king of Denmark loved eating blueberry so much that his teeth were dyed blue and he was known as the king of bluetooth, bluetooth became a synonym for communication. A thousand years later, when the new wireless code was introduced, people named it bluetooth. In 1995, Ericsson came up with the concept of bluetooth. The bluetooth specification USES the microwave frequency band to work. The transmission rate is 1M bytes per second and the KIOSK Printer China. The transmission power can reach 100 meters by increasing the transmission power. Bluetooth technology is a global open, on a global scale has good compatibility, can lower the cost of the world's intangible bluetooth networks into an organic whole of bluetooth nature has been sending out the glamour business performance and portability. With the popularity of camera phones, bluetooth almost become the standard of modern mobile phone, people demand for photo print function anytime and anywhere has appeared, and based on bluetooth wireless printing is the best solution, more and more printer manufacturers launched a photo printer with bluetooth technology. Bluetooth technology costs more than infrared, but it also has higher performance. The transmission speed is more efficient, the distance is far, and it is not limited by obstacles. At the same time, it has good safety performance and strong anti-interference ability. The use of bluetooth technology printers can greatly improve office efficiency, so that office equipment can be connected without cables. Using a camera phone with bluetooth technology, you can also easily start wireless printing, convenient and fast.

About heat sensitive paper

WIFI POS Printer machine currently USES thermal printers. The following are the relevant materials of thermal printers. I hope you can understand this knowledge.

Thermal printer can only use a dedicated thermal paper, thermal paper coated with a layer of will react when it is heated and the coating color, similar to the film, but this will change color after coating is heated, the use of the properties of thermosensitive coating, thermal printing technology came into being.

WIFI POS Printer Wholesale paper is a special coated paper, its appearance and ordinary white paper similar. Thermal paper surface is smooth, is by the ordinary paper as paper base, top layer coating thermal hair color layer, coated on one side of the surface of ordinary paper, hair color layer is composed of adhesive, chromogenic agent, colorless dye (or leuco dye), not to be separated, microcapsule chemical reactions in a state of "latent". When the thermal sensitive paper meets the hot print head, the colorant and colorless dye in the print head react chemically and change color, forming the picture and text.

Thermal paper were placed above 70 ℃ environment, thermal coating began to change color. The reason why it changes color also depends on its composition.

There are two kinds of thermal sensitive components in POS Printer Brazil paper coating. The other is a colorant. This kind of thermal sensitive paper is also called two-component chemical thermal sensitive recording paper.

POS Printer Russian Commonly used as colorless dyes are: triphenyltoluene alkyl phthalide system of crystalline purple lactone (CVL), fluorane system, colorless benzoyl methylene blue (BLMB) or spiropyran system. Commonly used as colorant: para-hydroxybenzoic acid and its esters (PHBB, PHB), salicylic acid, 2, 4-dihydroxybenzoic acid or aromatic sulfone, etc.

Thermal paper after heated colorless dye color react with chromogenic agent, so the use of thermal paper receives signals on the fax machine to print or direct thermal printer to print, graphic display. Since there are many varieties of colorless dyes used, the colors of the letters displayed are different, such as blue, magenta, black, etc.

Bluetooth printer applications and advantages

Application field

Global bluetooth specification, can be widely used in bluetooth printer membership software, read the membership number, police, government affairs, environmental protection, health, detection of all walks of life, such as LCD Module Supplier, etc.

advantage

Easy to operate(Small Portable Receipt Printer)

Bluetooth technology is an instant, it does not require a fixed infrastructure, and easy to install and set up, don't need to cable connection can be realized, Label Printer China is very convenient to use, simply complete the matching can be put into use, operating the threshold is low.

Fast transmission speed

Compared with infrared and other methods, bluetooth transmission protocol has obvious advantages in speed. The maximum speed of bluetooth 4.0 theory reaches 24Mbps.

Although there are many advantages, the bluetooth transmission protocol, like other 2.4g devices, shares the signals of this frequency band, which inevitably leads to interference between signals. In addition, the bluetooth protocol is not a free technology, and Portable Receipt Printer manufacturer using the technology will have to pay a royalty fee to the organization, which will be included in the cost.
