Printer Mechanism is the core of the printer, Printer Mechanism quality determines the quality of the printer

The reason for the blurred printer printing

     Question 1. some words do not print out the reasons: print head(Printer Mechanism) dirty, typographical errors.
Methods: cleaning the print head, layout, when to see if the printed word overlap together, and re-typesetting.

Question 2. the print is not clear and black line reasons: print head dirty or print head broken needle
Method: clean the print head, if not, then replace the print head(Printer Mechanism).

Question 3. the font is clear when printing, bar code is not clear Reason: bar code content too much, the density is too small.
Method: shorten the bar code content or increase the bar code density, for 200dpi and 300dpi machine, the bar code density is generally more than 7mils scale factor to 2 or 2 above, the micro-printer to print out the bar code is clear.

Classification and Differences of Micro Printers

Mini Printer categories: thermal printers, dot matrix printers.
Micro printer products are widely used in transportation, commercial, hotel, banking, catering services industry, with the domestic micro-users are increasingly mature, users of micro-printing performance requirements continue to pursue perfection.
Thermal printer is mainly used: shopping malls bills, shopping notes, medical equipment, banking equipment, queuing machines.
Needle-type printer is mainly used: tax control, invoices, taxis and so on.
Stylus, thermal printer distinction
Thermal printer: Thermal Printer Mechanism heat, so that changes in thermal paper to form text content printed on paper, print speed, thermal head maintenance is relatively simple. (The printed text will disappear due to time or temperature changes, but advanced thermal paper will still save the text for a long time.)
Needle printer: Prints the needle to hit the ribbon, forms the writing content to print on the paper, the printing speed is slower, the needle print head(Printer Mechanism) maintenance is more complex, moreover the price is more expensive.

Development Trend of POS Ticket Printer

Now more and more intense competition in all walks of life, POS paper industry even more so. From the previous years of production capacity competition, to the subsequent channel competition, and price competition, until the promotion of competition, competition has penetrated into all aspects of POS marketing. In the competition to the extent of white-hot, the terminal has become the last marketing magic, this is the so-called winning end. Terminal management of enterprise life and death, although the truth of all people understand, however, so that the printer operators feel frustrated that the actual operation of the terminal management is more difficult. This is reflected in the terminal operation.
POS printers are widely used in various industries, such as taxation, supermarkets, convenience stores, postal services, banking, entertainment, enterprises, catering hotels and so on. Now there are many in the mini printer, each has its own scope. POS ticket printer contains many, and now for the concept of micro-printer is also more vague, classification is not clear. We do not talk about micro printer module here, only as a finished micro printer.

How to choose small ticket printer and label printer

   With the advent of the information age, supermarkets, restaurants, health care, banking, public service places and other industries increasingly use a wide range of small ticket printers and label printers, but how to select and evaluate micro-printer There is no uniform standard of merit. I think the main should be from Printer Mechanism quality, transmission system, fault diagnosis and protection technology, cutter reliability and life, ergonomic design philosophy, the main structure of materials, after-sales service security system, and comprehensive cost-effective aspects of comprehensive inspection.

  1, the movement is the core component of the printer, determines the product quality and life. Currently on the market are mainly metal structure Printer Mechanism and plastic movement two. Metal structure movement with high mechanical strength, good heat dissipation and other advantages, access to the user's generally affirmed. Another Printer Mechanism of the manufacturer's product quality and life is also very important.

  2, the transmission system of high efficiency, stability, long life, maintenance-free printer is to ensure the use of an important evaluation index.

  3, the application of fault diagnosis and protection technology can fully guarantee the reliability of the printing process.

  4, the cutter is an important part of the micro printer.

  5, advanced ergonomic design concepts in the application of the product can effectively improve the ease of use and affinity products.

  6, the main body material on the printer's structure, shape, texture has a great impact.

  7, there is no one hundred percent trouble-free products, which depends on the company's after-sales service security system

  8, the current domestic micro printer variety and many manufacturers, quite a mixed bag, price war brutal, polish eyes, insist on only the election, not afraid of your priority price-performance principle, you must be the winner!

Principle and advantages of Thermal transfer printer

    Thermal transfer technology, simply, is the use of specialized ribbon, through a similar facsimile printer head(Printer Mechanism) works, the carbon powder coating on the way through the heating, transfer to paper or other types of materials , Because the coating material on the ribbon can be selected according to need to produce strong adhesion, coupled with the choice of print media, print can ensure that the writing is not affected by the outside world.

Features of Two Kinds of Universal Micro Printers

First, the needle-type micro-printer: pin-type micro-printer The more common micro-printer, the domestic very early Epson print head (Printer Mechanism) products. Needle punch has the advantage that the printed documents can be stored for a long time, of course, you buy the ink on the ribbon must be of good quality, so many convenience stores are used in micro-hit, and because the needle print head control Simple, you can use a relatively cheap control panel program to produce, so cheaper. However, there are many shortcomings of the needle to play: noise, print speed, print head loss quickly, you need to change the ribbon, because the relationship between the principle, these are insurmountable.
Second, thermal micro-printer: pin-type micro-printer is also more common type of micro-printer, but the micro-printer than the needle came out later. Thermal printer prints fast, the noise is small, the Printer Mechanism rarely appears the mechanical loss, and does not need the ribbon, has exempted the change ribbon the trouble. But it also has shortcomings, because it is the use of thermal paper, it can not be indefinitely preserved, in the dark conditions can save a year to five years, there are long-term thermal paper can be stored for ten years.

How to Extend Printer head Life

How to extend the life of the print head, the printer is the most fragile vulnerable to damage the device?
    It is like a car is a loss of goods, will eventually be damaged, but constantly pay attention to maintenance, you can extend the life of the print head. PRE-MAINTENANCE For best results, clean the print head once for each roll of ribbon or roll of thermal paper. CAUTION When cleaning the printer head(Printer Mechanism), remove the ring to prevent scratching the printer head(Printer Mechanism) and use a grounded metal strap or antistatic mat to prevent static damage to the printer head(Printer Mechanism). Use a 70% alcohol swab, first turn the printer off and open the print head, brush with a small amount of cotton cloth on the mechanical part of the printer, or gently blow off dust (eg rollers, paper / tape sensors and printer head(Printer Mechanism)s). Do not use any hard metal or worn tools (such as a screwdriver) to grind the print head contaminants. With a cotton rod with alcohol pressure in the print head from beginning to end rub, and then rotate the roller, use it to turn the edge of the rub, dirty cotton swab not to use. Factors that cause premature damage to the printer head(Printer Mechanism) - Labels / tape Long-term movement through the printer head(Printer Mechanism) wears the protective coating of the ceramic coating, exposing the printer head(Printer Mechanism) pins (spots) and eventually destroying them.
 In order to avoid abrasions
• Clean the print head frequently and use a smooth, heat-transfer ribbon with a backing film to reduce friction.
• Minimize printer head(Printer Mechanism) pressure and print temperature.
• Ensure that the ribbon width is wider than the label to prevent the exposed print head from being scratched by the label. The dirty print head caused by the back layer of the ribbon will need high temperature, high pressure, high speed and other settings after being contaminated by thermal paper and thermal transfer ribbon. The accumulation of contaminants on the printer head(Printer Mechanism) pins creates heat transfer obstructions that affect the print image quality. The increase in contamination gradually reduces the print quality and appears to be dull or damaged. Contaminants and make the soaked cotton swab difficult to clean. In order to avoid the back of the ribbon caused by dirty.
· Use a heat transfer ribbon that has been protected with a backing layer, which must be referenced to a non-tacky ribbon, with both static dissipation and lubrication.
• Always do print head maintenance.
· Use our protective printer head(Printer Mechanism) film to quickly and easily remove print head waste accumulation.

Development and Classification of Micro Printer

      With the continuous improvement of people's living needs and the acceleration of market segmentation, the miniaturization of the printer has become a trend, and the demand for micro-printers has been increasing. From the beginning of 2006 the amount of micro-terminal each year are doubling. Such as the financial industry along with a large number of bank credit card issuance, increasing the number of financial POS; in recent years the country to expand domestic demand policy has also improved the sense of service banking; consumer industry is to let people clearly consumption-oriented, and strive to do all the transactions Have a certificate in hand. Micro-play has been widely used in various industries, such as instrumentation, supermarkets, convenience stores, postal services, banking, tobacco monopoly, utility meter reading, mobile police systems, mobile government systems, car driving recorder and so on.

     MINI printer in accordance with the print mode is divided into pin-type micro-printer, thermal micro-printer and thermal transfer micro-printer. Pin printing is used to print the needle hit the ribbon to the ribbon of ink printed on the paper; thermal micro-heating method used to make the paper coated with heat-sensitive media on the discoloration; thermal transfer is The ribbon on the toner by heating the way printed on the printing paper, the current addition to bar code printers and ticket printers, in other areas of domestic use rarely; in addition to micro-font printer, this printer used in the taxi. The current market share is the largest thermal micro-pin and pin-type micro-fight.

Industry Analysis of Portable Printers

The market demand for portable printers: people's demand for printed products is rising over time, the original stage, people's requirements for the printer is to print faster, better quality, however, technical progress and the real needs of the The above requirements become no longer strong, the current print quality of the printer has been very good, the space can be developed not too much, the print speed has also been a big leap, so people began to pondering other needs, such as portable printing . Portable printing on the printer has two main needs, one is the mobility, one is small, in the final analysis is the need for "small" printer, out of the bulky shape in order to portable mobile. Today, with the development of mobile office, the market is equipped with a variety of office printing equipment is also more user-friendly and comprehensive, "short and pithy" products applied to the field is more extensive, for those who work outside the perennial people are no exception , So, portable printer by more and more industry attention.

Portable printer is the most important features: portable printers are generally used for portable use, with small size, light weight, battery-powered, easy to carry and so on.

Portable printers introduced the development prospects: portable printer as a new product is in the development period, a lot of technology and functionality are in the exploratory stage, and this development will last a long time, the current market situation is far from mature market . Mainly in the following areas: portable Printer Mechanism is the print output core device, is the highest cost, high technical content, manufacturing process requirements are very complex key components. At present, the domestic brands of portable printers used for overseas procurement movement, movement procurement costs are the key factors affecting the cost of their products.

How to maintain of barcode printer head

1. Try to use labels and ribbons provided by your barcode printer agents, because at least they understand the printer's characteristics and are more likely to appreciate the importance and cost of the printer head.

2. Do not put the dust on the ground has been lost or no good label on the machine to use.

3. Do not want to print a little black away free to adjust the print head temperature, as long as the clear can be printed can be.

4. The horizontal and vertical pressure of the bar code Printer Module should be accurate and not cause the phenomenon that the burden is not even and break the needle.

5. For each three-volume ribbon, wipe the barcode with a cotton swab and alcohol, and wipe the bar with a clean cloth, and then brush the dust inside the machine.

Classification of Micro printer

    There are four main types of mini printer: wearable, integrated handheld, car-mounted and trolley-mounted.

Wearable

The user can wear the printer with a belt clip or shoulder strap. With the printer in place of the other carrying options, users can free up their hands to perform other tasks and reduce fatigue, especially if the printer is heavily used or is carried all day. Using the belt clip or shoulder strap, the user can comfortably carry larger and heavier printers, which is useful when additional media capacity or a wider label is required.

Handheld

Handheld printer is a portable computer with a combination of devices. The printer may be made as a detachable component stuck on the terminal unit, or incorporated as an integral unit. The combination of printer and handheld design eliminates the need for cable connections and the wireless connection between the printer and the computer. Users should test all-in-one models to ensure they are durable enough to remain in use after a fall, and their ergonomic design allows comfortable one-handed use.

Car mounted

Mobile printers can be installed on most vehicles, including forklifts and freight trucks. Installation can be permanent, for in-vehicle operation, or it can be disassembled to allow the printer to be taken out of the service point, for example, in goods delivery or route account processing. The mobile printer is designed to withstand shock and vibration in a mobile environment, and its power management, media handling and user interface functions are optimized for mobile applications. Printer Modules

Cart mounted

Desktop and desktop printers can be mounted on carts for mobility. Typical applications include distribution centers, signage, dual media, and other print jobs that require high capacity output or large media specifications. Trolley-mounted printers require power and are typically used with a PC or a portable computer mounted on a cart.

How to clean printer head

Inkjet printer in a long time without or after a period of time, there will be print is not clear, breakpoints, broken lines and other failures, then need to use the Printer Mechanism cleaning method to solve. Most inkjet printers automatically clean the Printer Mechanism when it is turned on and have a button to clean the Printer Mechanism. Such as Canon most of the inkjet printer with fast cleaning, regular cleaning and thorough cleaning of the third gear cleaning function, the specific cleaning operation, please refer to the inkjet printer operating manual for the steps on it. However, if the printing is not satisfactory after several consecutive cleaning, it should be the ink has run out, you need to replace the cartridge. When the cartridge is not in use, it is best not to remove it, otherwise it will cause a waste of ink or printer ink measurement errors. In general, the printer's ink on the printer within a short time does not occur like hardening deterioration, so we do not need to take out the cartridge. However, if you do not really long-term use of the printer, then you need to take out the cartridge, which can prevent ink deterioration, but also to ensure the life of the nozzle.
If the automatic cleaning method fails to prove more serious congestion is usually a long time the printer useless or use the process of power, the nozzle is not caused by reset. With the syringe against the nozzle, constantly pulling the pressure device, so high-speed air flow cleaning nozzle, and suck out the remaining ink, is a ink-saving cleaning method.
The manual cleaning method does not work, we must prepare to open the printer for the following operations. Turn off the power first, and unplug the plug, completely disconnect the power. Remove the moving shaft and turn the belt, then carefully pick up the Printer Mechanism, rinse with distilled water. And then use syringes and soft hose to form a spray system, inserted into the ink hole to be cleaned. Two steps must be exceptionally careful, absolutely can not let the water stained circuit board, if unfortunately wet circuit board should be immediately dried with a hair dryer. Finally, replace the printer, the implementation of software cleaning program again, so that the ink inside the nozzle of distilled water washed away.
Long-term unused integrated Printer Module due to dry ink and plug the nozzle, can be soaked with hot water and then cleaned. Cleaning the Printer Mechanism should note the following points: A, do not use sharp objects cleaning nozzle, can not impact the nozzle, do not touch the nozzle; B, can not be charged in the state of demolition, install the nozzle, not hand or other items contact print car Of the electrical contacts; C, the nozzle can not be removed from the printer alone, not the nozzle on the dusty place.

The Role of Thermal Printers in Electronic Commerce

    In recent years, the rise of electricity providers, more and more people for online shopping has been from the beginning of the attempt to the subsequent habit, become the ultimate dependence. It is precisely because the online shopping service with unparalleled convenience, so a little size of the electric business every day to face the huge number of commodity circulation and the resulting large number of bills!
    Net purchases of goods produced by the receipts are mainly bills, bills, etc., they have high speed and clarity requirements, therefore, thermal printer is the best tool to solve this problem.
    Thermal printer works is the Printer Module is equipped with a semiconductor heating element, the print head heating and contact with the thermal printing paper can print out the desired pattern, the principle and thermal-type fax machines similar. The image is generated by heating and creating a chemical reaction in the film. This thermal printer chemical reaction is carried out at a certain temperature. High temperature will accelerate this chemical reaction. When the temperature is lower than 60 ℃, the paper takes quite a long, even a few years time to become dark; and when the temperature is 200 ℃, this reflection will be completed within a few microseconds.
Thermal printer characteristics
    Thermal printer is a conventional bill printing equipment, is a set of software and hardware in one embedded real-time processing system. It has small size, light weight, speed, low noise, print clear, easy to use, etc., and its ease of use and adaptability better. But the shortcomings of thermal printers is obvious, that is, it can not be printed out of the permanent preservation of documents, even the best use of thermal paper, can only save about 10 years.
    In the print media, the thermal printer can only use a special thermal paper, this print media surface will have a chemical reaction and will change color coating, and in order to achieve the print output. Thermal paper coating in the heat-sensitive components are mainly two: one is leuco dye or leuco dye; the other is the developer; when the thermal paper heat, they will produce a chemical reaction, which Showing different colors, such as blue, black, purple and so on.
Classification of thermal printers
    Thermal printer is mainly based on the arrangement of thermal components and classification, can be divided into row-type thermal and column-type thermal. Column thermal is an early product, mainly used in some of the printing speed is not demanding occasions. Line-type thermal technology is the last century 90's, the printing speed is much faster than the thermal column, the fastest speed has reached 200mm / sec.
The Application of Thermal Printer
    Thermal printing technology was first used in the fax machine, the basic principle is to receive data into the lattice of the printer signal to control the heating of the thermal unit, the thermal paper heat-sensitive coating heating development. At present, the thermal printer has been in the financial industry, logistics, medical and other fields are widely used.
    Although the application areas of Thermal Printer Mechanism have strong industry characteristics, but also gradually began to apply to the personal field.

The Application of Micro Printer in Bank

Application of thermal printer mechanism in banking terminal

The Application of Mini printer in Bank Self service Terminal. In recent years, with the advancement of science and technology, the opening of the banking business and the fierce competition environment, banks must provide more efficient and convenient services to attract customers, and customers' demands for bank timeliness are also increasing. Bank "," self-service banking "business will emerge as the times require. So, micro-printer in the bank self-service terminal application which?

Bank information inquiry machine, transfer machine and other non-cash trading terminal, usually developed by domestic manufacturers, lower cost, is a strong complement and extension of the banking business. This type of equipment on the print module requirements are slightly lower, the function usually only need the ordinary printing function, and some even the black mark detection function is unnecessary, but the basic needs of automatic cutting function, print Chinese function, but requires high reliability, performance Mainly to the mid-range, usually without prsenter, on the paper near the large roll of functional requirements is not strong.

Because such terminals tend to be delicate, compact, beautiful appearance, etc., leaving the print module space is usually small, the general purchase of spare parts to the size of the cabinet according to the flexible installation of print module components, components generally include Printer Mechanisms, printer The printer control board, the special power source and so on. The components can be designed to form the printing structure unit through the frame and the paper supporting frame. The components can also be installed in different places according to the actual situation, such as the ultra-thin cabinet, Type cabinets and so on.

Characteristics of Printer industry

The printer is currently dominated by the United States, Japan, Korea, the three major countries, the brand as HP, Canon, Samsung, Hitachi and other international brands. Why has the printer been monopolized in these three countries? One to because it is a high-risk, high-input industries; Second, the patent barrier to this industry is relatively high, the technical difficulty is also high. The third characteristic of the Kiosk printer is information security problems. According to foreign authorities survey, there are three ways of information security leaks, one E-mail leak, a mobile storage leak, there is a print leak. And we do when making their own domestic printer, do not reserve loopholes, no back door, no communication module and information backup function, does not provide firmware host-side download function, custom compression and encryption algorithms to solve the security risks. This is our independent intellectual property rights, belonging to the Chinese people an important reason for the printer. Printer Mechanisms

Application of EM1X in Self service Terminal
