An extended Foreign Device Interface (FDI) to external devices provides point of sale accounting for use of a Multi-Function Device (MFD). Simple Network Management Protocol (SNMP) can be used, in addition to the very limited page oriented interface used on copiers, to access much more detailed information about a job, permitting accurate billing by feature use, including for scan only jobs that are not currently supported. The interface also permits the external device to control job status, allowing approval of a job only after a complete cost has been computed.
