When there is only one computer, it's not fully equipped. The text and pictures that the computer wants to export are made from our printer, which is one of the output devices for computer images, printing the results of computer processing on the relevant medium。
In general, there are three indicators of the printer's functionality, the resolution of printing, the speed of printing and noise. There are three types of printers, laser printers, inkjet printers and needle printers, and today we look at needle printers。
Printers are not available in the workplace
While there is no apparent difference between needle printers, the need for specialization and specialization has led to the emergence of different types of needle printers, such as “general needle printers”, “clip printers”, “line printers” and “high-speed needle printers”, which are products to be exported from different business line areas。
More banks
With the spread of electronicization in all industries, needle printers dedicated to counter operations such as banking, post offices and social security services have been rapidly promoted and applied, and some operations require the retention of documents, both for users and for business, so that only needle printers can quickly complete the reproduction of documents and provide efficient services to users。
Needle printers form fonts by hitting the double-written paper with 24 needles in the head, and in use users can select multi-link paper according to demand, which is commonly used as two, three, four-link paper, also using six-link printer paper。
Multi-coalted paper printing is done using carbon-free overlaying techniques, which, like ordinary hand-written overlaying paper, automatically appear on the lower paper when multiple double-written paper folds together on the top floor. During the reproduction process, pentips need to put some pressure on the duplicate paper in order for the paper below to have the same handwriting。
The rationale for needle printing (source: p. Baidu. Com)
A needle printer has a special working method, printing needles when printed, printing colours on paper, and needles during printing will always put pressure on paper, so that multiple layers of duplicate paper can print the same effect, so that, in addition to the first piece of paper, the lower part of the paper will also display the handwriting, thus achieving multiple printing。
And why can't ink printing and laser printing do that? The inkjet printer is sprayed on the paper surface through the nozzle, which does not exert any pressure on the paper, so even if the multiple double-written paper is printed, only the first paper will be printed, and the paper below will not appear. The laser printer, on the other hand, transfers the ink to the paper surface through a selenium drum, which exerts the same power on all parts of the paper during the reproduction process, regardless of the print content, and therefore cannot be properly duplicated. Only the first piece of paper printed in multiple groups will be printed on the first piece of paper, and the paper below will not appear in writing。

Inkjet printers and laser printers are unable to print on polygaps because of the properties of polygaps. Only needle printers are pressurized needles, needles are printed on paper with a degree of strength and can leave a mark on several layers of paper, single printing is done quickly only by needle printers, general needle printers are easy to use, and printing is extremely easy to break if colour belts are not suitable and paper quality is poor. One of the disadvantages of needle-printing is that it is slow, and it is slower to print because of unique needle-trip motion。
The needle piercs
The widespread application of needle printers in the financial system and the unique printing of instruments, documents, vouchers, statements and tax returns in financial applications require multi-layer penetrating printing, which is one of the advantages of needle printers over other printing techniques. It also avoids binding problems and allows originals and copies to be visible, which is something that cannot be done with ink printing and laser printing。
The key to a needle printer is to see the lifetime of the head of printing, where a good needle is typically designed in a new high-density, high-resilient printing head, which is designed in a compact manner and enhances the heat-dispersion function, which can produce high-copy capacity and long-lived needle life of up to 400 million times per needle, while the average time of the whole machine is high, which also represents the high reliability of the printer, and the average time of a good needle master is usually 10,000 hours。
The needle is right next to us
The general assembly of the world olympic movement of 1964 was held in tokyo. At that time, eppson, which was dedicated to the provision of timing products, developed, inter alia, a crystal precise timesheet 951 and a printed timescale. The original printer is a print-type time-sec, a so-called print-type time-sec, which, if named, means an electronic record-keeping device combining a printing time machine with a measuring time device。
It is combined with pistols, pvs, photo readers, and is mainly used in the human race that has difficulty measuring speed and can automatically record the time spent in the competition. These two products not only made a difference at that time, but also provided a rich research and development base and opportunities for future corporate transformation and diversification。
In 1978, eppson released needle printers (7 needles) tp-80, which received a great deal of approval. The advent of mp-80 (9 needles) in 1980 was also a global shock, with the market share of mp-80 in japan reaching more than 60 per cent in the second year, and the united states market gaining a high rating, gradually becoming the first global mainstream needle printer for pc products. In the past five years, china's needle printer exports have accounted for more than 70 per cent of the global market, and china's needle printer market continues to have strong momentum。
The needles are widely used
In 1988, eppson took the lead in introducing 1600k of needle printers in industry 1, with a cumulative sale of 3 million relays. The emergence of this printer has led to the development of printers throughout china. Neither ink-jet printing nor laser printing is currently a substitute for needle-printing. After reading the article, a wide range of netizens have developed a certain understanding of needle injections, which are highly stable and have a very low failure rate, especially with very good repetition, even if the last link, the print print is equally clear, with high-quality positive colour belts, the ink quality is good, the long-term preservation of documents does not affect information recognition, and long-term retention checks are not problematic。
Now that we're still in a lot of use in our lives, as the electronicization of the instrument advances, needles may slowly exit the historical arena。
