Abstract
Postal franking apparatus in which both semi-permanent and variable information to be printed onto an envelope is stored electrically in a memory and is read out to form printing control signals for controlling a thermal printer containing thermally activable inking means at a printing station into which the envelope is placed. The thermal printer is in the form of an elongate conductive plate having a large plurality of electrical connections along its length to which are fed the printing control signals in synchronized relationship to passage of the envelope, the plate being of sufficiently high resistivity that only localized areas thereof are heated by the currents associated with the control signals, and ink is applied to the envelope only at the heated localities.
