Why thermal print receipts can't keep for a long time?

Thermal paper is coated with a chemical that changes color when heat is applied. This means that when a thermal printer applies heat to the paper, it creates the image or text on the paper. However, the chemical used in thermal paper is not very stable and degrades over time, causing the text or image to fade. Additionally, thermal paper is sensitive to heat, light, and humidity. Exposure to any of these elements can cause the paper to yellow, fade, or become brittle, which can make it difficult to read the printout. This sensitivity makes thermal paper receipts unsuitable for long-term storage. Moreover, the chemical used in the thermal paper can also be harmful to the environment. Thermal paper receipts often contain bisphenol A (BPA), a chemical that has been linked to health problems. As a result, many countries have banned the use of BPA in thermal paper, which can further compromise its durability. In conclusion, thermal paper receipts are not suitable for long-term storage due t

Can I use dot matrix printers to print barcodes?

Why my thermal print is getting blurry?

 There could be several reasons why a thermal print is getting blurry: Worn-out print head: The print head is the component of a thermal printer that comes in contact with the thermal paper and applies heat to create the image. If the print head is worn out, it may not apply enough heat evenly, leading to blurry or faint prints. Dirty print head: If the print head is dirty, it can cause the prints to become blurry. Dirt or debris on the print head can prevent it from making proper contact with the thermal paper, resulting in incomplete or uneven printing. Low-quality thermal paper: The quality of the thermal paper can also affect the quality of the prints. Low-quality paper may not be able to handle the heat generated by the print head, leading to blurry prints. Fading ink: Over time, the ink on the thermal paper can fade, resulting in blurry prints. This can happen if the paper is exposed to direct sunlight or high temperatures. Printer settings: If the printer settings are not optimi

Can I re-use barcode printer ribbon?
