Thermal Printer Supplies can be divided into thermal line dot system and thermal serial dot system according to the arrangement of thermal elements. As an early product, linear Panel Mount Thermal Printer is mainly used in some occasions with low requirements for printing speed, and has been used in its products by domestic authors. The line type thermal sensitivity belongs to the technology of Portable Printer Supplier. Its printing speed is much faster than the line type thermal sensitivity, and the fastest speed has reached 80mm Thermal Printer. To achieve high-speed thermal printing, in addition to the selection of high-speed thermal printing head, there must be a corresponding control board with it.

Thermal Printer Supplies technology was first used in fax machines. Its basic principle is to convert the data received by the printer into a dot matrix signal to control the heating of thermal sensitive unit, and heat the thermal coating on the thermal paper to develop. Portable Printer Supplier have been widely used in POS terminal systems, banking systems, medical devices and other fields.

Thermal Receipt Printer can only use special thermosensitive paper. Thermosensitive paper is coated with a coating that will produce chemical reactions and change color when heated, similar to photosensitive film. However, this layer of coating will change color when heated.

Thermal KIOSK Receipt Printer technology is the key element, thermal printing machine on a row of tiny semiconductor components, these components close together, ranging from 200 dpi to 600 dpi, these components must be in current through is quickly produce high temperature, when the thermal paper coating meet these components, temperature within a very short time increases, the thermal paper coating chemical reaction occurs, color.

After receiving the printed data, the thermal printer converts the printed data into bitmap data, and then controls the heating element on the printing movement through the current according to the point of the bitmap data, thus turning the printed data into the printed content on the printing paper.

(1) data translation: in order to print complete words and images, in addition to the function of the laser printer itself, the content to be printed must be edited into a computer language with a certain format by using a word or image processing software or graphics processing software. The content described is determined by computer editing software and has nothing to do with Thermal Portable Label Printer Manufacturer. When we select the print command, and determine the print button, the computer sends the edited data through a printer interface to a printer, the printer driver to print the content of explanation, and change printer can identify the language (language) is also called the printer, the printer to print out has been edited according to their own language text or image.

Different types of Thermal Portable Label Printer use different drivers for different printing languages. There are also compatible printer drivers. Production of laser printers, commonly used standard printing language PCL5 or PCL6.

(2) data transmission: there are many communication ports between the printer and the computer, and the common one is "serial port" or "parallel port". EP P/ECP (KIOSK Printer China) is referred to as Enhanced /Extended parallel. "Serial port" is seldom used because of its slow speed. Others, such as the SCSI interface, are mostly used on higher-end printers because of their speed. Other printers communicate with computers using the video interface (VDO), which is different from other interfaces. Its data is done by another "video conversion card", but because it shares memory with the computer, the computer is required to have enough cache space. The general printing typesetting industry USES this interface printer more. Some high-grade printers have multiple interfaces and can connect multiple computers at the same time. Many of these Portable Printer Supplier come with faster USB ports.

When the printing controller receives the data from the computer, the printer generally adopts two ways of working: one is to send the data directly to the interpreter for printing, which is called "segment working mode". Printers that work in this way do not need a lot of cache and memory. Ordinary printers usually work in this way. The other is to store the transmitted data on the internal hard disk of the printer and print it out whenever you need it. The advantage is that when many users share a printer, they can simultaneously issue a print command without having to wait and save the waiting time for data communication, but it is also more expensive.
