To produce receipts, a roll of thermal paper is inserted into the slot between the thermal head and rubber roll. The printer sends an electric current to the heating elements of the thermal head that generates the heat. When heat is applied to the paper, the printer generates different colors for printing out text, symbols or pictures. No ink is necessary.
