Electro-thermic printing device

摘要: An electrothermal printer for non-impact printing on plain paper which makes use of a ribbon is made up substrate having thermal transferrable ink coated the surface towards and coating electrically resistive material other side. The held in contact with while plurality selectively energizable electrodes are side ribbon. energized causing current to pass through an incremental portion another electrode said short distance from electrodes. causes enough I2R heating soften wax directly opposite heated portion. softened transfers sheet as dot or line.
