Abstract
Methods enabling the use of an office printer connected to a microcomputer in order to print legitimate postal marks. It uses a cartridge of special fonts in which there are stored the franking marks according to the standards laid down for the printer. A known security component is provided, on the one hand to protect access to the memory contained in the cartridge and, on the other hand, to perform the computation, for each printing of a franking mark, of a security mark that contains encrypted information elements that are readable by the postal authority, enabling the franking mark to be authenticated. It provides for the elimination of specific franking machines and limits the handling operations to the handling of a small-sized cartridge.
