Definition - What does Thermal Paper mean?
Techopedia explains Thermal Paper
Reliability, durability and high-definition images are characteristics of printing on thermal paper. Printing on thermal paper is faster than other modes of printing technologies, and this helps in high-volume printouts. Again, the printing involved is quieter, and so high-output printing is a smooth experience. The print images on thermal paper are of high quality and are also capable of handling high-quality barcode scans. Apart from being economical and low in energy consumption for the printer, thermal papers offer great flexibility with respect to size. Different formats of printing are supported by thermal papers. The images do not fade or smudge over time and last for a longer period of time. Another advantage of using thermal paper for printing is the low maintenance cost as there are fewer movements involved in such printers.
For these reasons, the technology is used in various sectors such as health care, retail, etc. It is also used in most transaction documents, point-of-sale receipts and some faxes.
