A computer system includes workstations and a peripheral having a processor. The workstations and the peripheral communicate via email over a network. Email messages include commands and requests that control access to status and reconfiguration of the peripheral, establish subscriptions to status of the peripheral, and invoke reconfiguration of the peripheral. Email messages also include publications of the status of the peripheral according to reporting criteria. Reporting criteria identify a report of process or state variables, define publication criteria for directing the monitoring of state variables, and define delivery criteria to avoid network undesirable network traffic and irritating addressees of subscriptions.
