Why should businesses use thermal paper and thermal printers to print shopping tickets instead of laser or inkjet printers that we are more familiar with?
First of all, laser or inkjet printers require complex devices to transfer ink or toner from the printer to the paper. Both printers are relatively large in size and usually need to use AC as the power supply; Businesses often need smaller printers, especially when selling goods outdoors or on transportation vehicles such as planes and trains. It is obviously unrealistic to carry a heavy printer to print receipts for customers.
Secondly, replacing ink cartridges or toners in laser or inkjet printers is often time-consuming and laborious. If customers are delayed in paying their bills, businesses and consumers are very reluctant to see it.
If thermal printer and thermal paper are used to replace laser or inkjet printer, these problems will be solved. Since the ink has been stored on paper in advance, thermal printers no longer need complex structures to store and transmit ink, and can be very small. And it can be battery driven, which is very suitable for businesses to carry, especially in the outdoors or on vehicles to print receipts for customers. Due to its simple structure, the thermal printer is also very easy to maintain. Users do not need to worry about replacing the ink cartridge, as long as they quickly replace a new roll of thermal paper when the paper is used up. In addition, the thermal printer has fast printing speed and low noise, which is very suitable for use in shopping malls. Because of these advantages, thermal printing is not only the preferred way to print shopping tickets, but also often used to print tickets, labels and even faxes.
Thermal paper also has a big defect, that is, the handwriting on the printed document will fade gradually after it is stored for a period of time. In order to solve this problem, we will add an additional protective layer on the dye layer when producing thermal paper to minimize the contact between the dye and other chemicals, so that the documents printed with thermal paper can be preserved longer.
