The Okimate 10 by Oki Electric Industry was a low-cost 1980s color printer with interface "plug 'n print" modules for Commodore, Atari, IBM PC, and Apple Inc. home computers. Unlike thermal printers, which use thermal printing technology and require thermal paper, the Okimate used thermal transfer technology and was advertised as being able to print on any type of paper. In practice, however, printing to common printer/copier paper did not produce adequate results. Best results were obtained by printing to special "thermal transfer paper" which looks like ordinary copier paper but is actually an ultra-smooth paper for the wax-transfer to adhere to.
