Needle printer

　　Needle printer is a printing device with unique application fields.

　　From the perspective of working principle, a needle printer uses steel needles in the print head to strike the ribbon, printing the ink on the ribbon onto the paper to form characters and images. The number of pins in the print head varies, commonly including 9 pins, 24 pins, etc. The more pins there are, the higher the resolution and quality of the print. The ribbon of a needle printer is a consumable, which has a relatively low cost and is easy to replace.

　　In terms of printing quality, the printing effect of a dot matrix printer is mainly characterized by clear dot matrix characters. Although its performance in image printing is not as good as inkjet and laser printers, it has irreplaceable advantages in printing multi copy paper such as bills and reports. It can easily penetrate multiple layers of paper and achieve duplicate printing, which is crucial for fields such as finance and taxation that require printing multiple copies.

　　In terms of cost, needle printers themselves are relatively affordable, especially for some basic models. The price of ribbon is also relatively cheap, for example, a regular ribbon may only cost a few tens of yuan and can print a certain number of pages.

　　In terms of usage scenarios, needle printers are mainly used in industries that require printing multiple bills, such as banks, hospitals, logistics, and other fields. It is also suitable for printing some special forms, reports, etc., which require long-term storage and do not have particularly high requirements for printing quality. The stability and durability of the needle printer can meet these needs.
