Abstract
A machine for printing addresses on envelopes or cards from a plurality of master cards each having an address and other indicia imprinted thereon with heat conducting material, such as carbon. Master cards and envelopes or cards to be printed are delivered to a printing zone in face-to-face relationship together with a length of printing tape interposed between each master card and its respective envelope or card to be printed. The tape has one surface coated with heat-transferable printing medium disposed in face-to-face relationship with the envelopes. The master cards, tape and envelopes or cards to be printed are pressed together at the printing zone where heat is applied to the heat conducting indicia on the master cards.
