Abstract
A franking machine is disclosed which has a microprocessor for carrying out accounting and control functions and in which printing of a franking impression is effected by ejecting droplets of ink from ink filled nozzles by means of selectively heatable elements which vaporize the ink or a constituent thereof to the rear of the nozzles and thereby eject the ink droplets. The nozzles may be stationary and be supplied with ink through a common pipe connected to a reservoir or the nozzles may be constituted by pores in a belt which is driven through an ink reservoir and then past the heatable elements.
