Inkless printing is a technology that allows images and text to be printed without the use of traditional ink. Instead, it utilizes heat to create images on specially coated paper. When the paper is heated, the coating changes color, producing the desired print. This method can be more environmentally friendly since it eliminates the need for ink cartridges. This printing technique is often used in devices like thermal printers, which are commonly found in receipt printers and label makers. Inkless printing can also reduce costs associated with purchasing and replacing ink, making it an economical choice for various applications.
