The printing device includes a dye tank (11-13) for containing a powdered vaporizable dye (C,M,Y), an entrance section (14) for liquefying the powdered vaporizable dye and a vaporizing section (17-19) for radiating a laser light beam onto the liquefied dye transported to it by the entrance section (14) for vaporizing the liquefied dye for thermal transcription of the vaporized dye onto a photographic paper (21). In this manner, printing may be made without employing an ink ribbon or a thermal head and hence the saving in power and the reduction in size and costs of the printing device may be achieved. Besides, the printing time may be shortened, while the size of the printing paper may be set freely. The photographic paper (2) includes a light absorbing layer (212) between a receptor layer (211) and a photographic paper base (214). Since the light absorbing layer is capable of absorbing the light efficiently for evolving heat efficiently, the receptor layer may be heated directly to assure a high quality of the printed picture. <IMAGE> <IMAGE> |
