Thermal paper (often supplied in roll form, and sometimes referred to as an audit roll) is a special fine paper that is coated with a material formulated to change color locally when exposed to heat. It is used in thermal printers , particularly in inexpensive devices such as adding machines , cash registers , and credit card terminals and ...
A thermal printer Bills and receipts are typically printed on thermal paper. [1]Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by passing paper with a thermochromic coating, commonly known as thermal paper, over a print head consisting of tiny electrically heated elements.
This is called thermal printing and was used in older model fax machines and is used in most shop till receipt printers. This is called direct thermal. This is called direct thermal. More complex is thermal transfer printing that melts print off a ribbon and onto the sheet of paper.
Thermal copier Pentacon PENTACOP 110 in a GDR Museum in Dresden. A thermal copier or thermocopier (used as a Tattoo transfer copier) is a kind of photocopi er based on the effect of heat. The original sheet feeds in conjunction with the "thermo-sensitive" paper, generating a copy on its specially treated surface.
It was a significant advance as no chemicals were required, other than those contained in the copy paper itself. A thin sheet of heat sensitive copy paper was placed on the original document to be copied, and exposed to infrared energy. Wherever the image on the original paper contained carbon, the image absorbed the infrared energy when heated.
Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.
