A security module is operatively disposed at the hardware/software interface within a printing apparatus. The module is disposed along a connection which acts as a medium for command signals to operate the printer hardware, and for status signals to indicate physical conditions within the hardware. The security module facilitates security procedures which control aspects of printer operation, particularly the creation of MICR characters.

A customer-replaceable supply accessory for a page printer, such as a toner cartridge or liquid-ink supply, includes a conductor which interacts with connectors within the printer to ensure proper installation of a given type of accessory. The conductor is exposed only within cavities on the accessory which receive springably-mounted extendible members. The extendible members serve to secure the accessory in position within the printer. The conductor is generally not apparent from the outside of the accessory.
