Printers are also divided into many types. According to wireless, they can be divided into ordinary printers and wireless printers. Wireless printers output text, pictures and other content through networks such as local area networks. In addition to this division method, printers also have types for different needs. The shopping receipts that we usually get when shopping in the supermarket use thermal paper, and printing on thermal paper requires a special thermal printer. We sometimes find in the supermarket that the small ticket we get has no content at all, it is a blank sheet of paper, which means that the thermal printer can't print. There are generally several reasons why the thermal printer cannot print characters. Let's take a look together.

   Thermal printers are aimed at thermal paper, and naturally need to be used with special thermal printing paper. If you are not using special thermal printing paper, the thermal printer cannot print words at all. A simple way to test whether the paper is thermal printing paper is to use your fingernail to draw a line on the paper. If there are black lines, the paper is thermal printing paper.

   Thermal printing paper is used in conjunction with a rubber roller. Sometimes the rubber roller does not press the thermal paper firmly, and the needle of the thermal printer will have poor contact with the thermal paper, so it is naturally impossible to print.

    If the user is using a thermal printer with a ribbon, it is recommended that the user check the ribbon to see if the ribbon can work normally when the words cannot be printed. If it can work normally, it is due to other reasons. If not, it is recommended that the user replace the ribbon.

   If the user has used the three methods mentioned above to check the thermal printer and still cannot eliminate the fault, at this time it is very likely that the thermal printer itself has a fault. It is recommended to go to the after-sales department of the purchaser to have the thermal printer carry out all-round troubleshooting and maintenance.
