Abstract
A value printing system is disclosed which provides for storing the indicia to be printed within a secure vault module. The vault module also provides for securely maintaining the system accounting data. Coupled to the vault module is a host module which in turn is coupled to a printer module, whereby the indicia are printed. The vault module and the host module are coupled together by a high speed communications bus which utilizes a memory interchange, or swapping, technique to transfer blocks of data bidirectionally between the vault and the host.
