Abstract
The machine is a card printer that carries out simultaneous black-and-white or color printing on both faces of a card. This machine uses two identical printers of the type using thermal printing heads and ribbons placed on either side of a device to guide and convey the card to be printed on. A device for the simultaneous positioning of the thermal printing heads enables each ink-bearing ribbon to be applied against one of the faces of the card when it comes under the heads. The invention can be applied to bank cards, entry cards, telephone cards.
