The web interface provides an Endpoint to register client Printers, printers are discovered using SNMP and page counters are sent to the backend so that reports can be generated using printer info.

Possible update to this NPM package -> https://www.npmjs.com/package/net-snmp, using PM2 to keek service runing after restarts.
