Everyone often encounters a lot of paper tickets in daily life, but carefully whether you find that the same is a small ticket, but the feeling of getting started is quite different. One kind of small ticket feels like ordinary paper, another kind of small ticket feels more smooth. What is the difference between them? Today I will tell you about two printing methods that are widely used in receipt printing.

    At present, in addition to daily documents, our daily life and work are also filled with various bills, from express receipts to restaurant receipts, shopping receipts and so on. The seemingly identical bills can be realized by two technologies: thermal printing and dot matrix printer. The previously mentioned bills that feel smoother to the touch are basically realized by thermal printing. So what are the characteristics of these two printing methods?

Dot matrix printer

    Dot matrix printers form fonts by hitting media such as paper with the needle in the print head. In use, users can choose multi-ply paper according to their needs. Generally, the commonly used multiply paper includes 2-ply, 3-ply, and 4-ply paper, as well as 6-ply printer paper. Multi-part paper printing is completed at one time and only a needle printer can quickly complete it.

     The characteristic of needle printing technology is that the needle hits the medium, and the force of the needle is transmitted to the paper medium through the ribbon, which can print multi-copy carbon paper. Due to the subtle differences in the needles, the printed documents are unique and difficult to fake.

    But needle printing also has its shortcomings, that is slow printing! Stylus printing has a slower printing speed because the needle adopts a reciprocating movement. Secondly, the ink ribbon of the dot matrix printer needs to be replaced frequently, the operation is complicated and the printing cost is high.

   Common applications: invoice printing, ticket printing, etc.

Thermal printing

    The thermal Label Printer is equipped with a semiconductor heating element on the print head. The print head heats and contacts the thermal printing paper and prints the required patterns. It is similar to a thermal fax machine. The image is generated by heating, generating a chemical reaction in the film.

     Compared with stylus printing, thermal printing has the advantage of being fast. Because the print head with the same width as the printed medium is adopted, the paper of thermal printer can reach the second output speed.

    However, thermal printing also has disadvantages. Because thermal paper is greatly affected by the environmental temperature, the printed bills have a shorter storage time. The printed bills will fade and blur in about three months and will be difficult to identify.

    Common applications: catering receipt printing, takeaway order printing, shopping receipt printing, etc.
