There is a known device that forms an image by contact-transferring a thermal transfer recording element onto plain paper based on the difference in melting heat generated by a heating body such as a thermal head, and is known as an am/contact-transfer printing device on plain paper. Images have the advantage of being highly durable and cannot be tampered with, but on the other hand, printed images are limited to line drawings or solid images, or images with extremely poor tone reproducibility even when halftone reproduction is performed. The drawback was that you could only get it.
