Collecting meter readings: email, SNMP and manual readings

Many printers, particularly Ricoh models, can be configured to email meter readings periodically. The provider does not need access to the local network: the printer reports directly. PrinterMS automatically assigns the incoming email to the correct printer and contract, extracts the reading and calculates charges. The limitation is setup: the printer must be configured to send reports, and support varies between brands.

SNMP (Simple Network Management Protocol) is a standard way to query network devices. A DCA queries printers on the local network and retrieves readings, toner levels and status. This offers broad coverage across brands and live data rather than only monthly reports.

The printer must be reachable on the network, and the agent must run on a server, small computer or Raspberry Pi. Collection can then be fully automatic. Read more about the PrinterMS multi-brand SNMP agent in the DCA glossary entry.

The oldest method is to visit or call the customer, read the counter on the display and enter it into a spreadsheet or system. This can work for a few printers. With hundreds, mistyped numbers, missed printers and late submissions become common sources of errors. It is useful as a fallback, but does not scale as the main method. Aim to make manual readings the exception.

Usually, a combination. Use email or SNMP as the automatic primary source, with manual readings for the few printers that fail to report. Most readings can then arrive without intervention, leaving only exceptions to investigate. PrinterMS handles all three sources and flags missing expected readings before you issue an incorrect or incomplete invoice.
