The printer used in the cash register uses a thermal printer, so what is the working principle?
working principle
Use chemically treated thermal media to darken as the media passes under the thermal printhead. Thermal printers do not use ink, toner or ribbon. The simple design makes the thermal printer durable and easy to use. Because there is no ribbon, thermal printers operate at a lower cost than thermal transfer printers. The pattern on the thermal media will fade over time. If the label is overexposed to heat, light, or other catalyst, the material will become darker and the barcode will not be read.
The readability of thermal labels varies greatly depending on the conditions of use, but the technology provides a sufficient lifetime for printing applications with nominal markings and many other common bar codes. For example, after six months of storage at the distribution center, the direct thermal tag can still be easily scanned for reading.
Thermal conversion principle
In thermal transfer printing, the thermal printhead heats the ribbon and the ink melts on the label material to form a pattern. The ribbon material is absorbed by the medium and the pattern forms part of the label. This technology provides pattern quality and durability that is unmatched by other on-demand printing technologies.
Thermal transfer printers accept a wider variety of media, including paper, polyester and polypropylene, than thermal printers. Thermal transfer printers produce durable rated labels, UL/CSA labels, labels and tickets, as well as wrist straps, permanent asset tags, racks and other logos.
Raw material selection
Wax is the most common and inexpensive option for many labeling applications. Resin ribbons improve heat and chemical resistance and are used in synthetic label materials. Resin-modified wax ribbons combine the best of both worlds and perform well on many label materials. To ensure print performance and durability, specific label materials and ribbons must be carefully selected. The choice of the ideal ribbon depends on the materials used in the label, the printer, and the environment. By choosing the right combination of media ribbons, users are able to produce high quality labels that are always readable during production, logistics and storage.
A1 LED Light Pad
When using, put the original on the first layer of the copy table, then take the normal A4 printing paper or drawing manuscript on the original, plug in the power supply to light the copy table, press the brightness you want, so it is very clear If you can see the pattern on the original clearly, you can directly copy the pattern according to the pattern. After you draw it, you can have two identical artworks!
