# SNMP Printer Monitoring: Toner, Pages & Status

Monitor network printers over SNMP with the standard Printer-MIB (RFC 3805) — track toner/supply levels, compute percentage, read page counts.

## Frequently asked questions

### How do I monitor printer toner with SNMP?

Poll prtMarkerSuppliesLevel (1.3.6.1.2.1.43.11.1.1.9) for the current level and prtMarkerSuppliesMaxCapacity (.8) for the maximum at the same supply index, then compute percentage as level ÷ max × 100. Handle the special values −2 (unknown) and −3 (some remaining, unquantifiable) as sentinels rather than numbers, and alert when the percentage drops below your reorder threshold.

### Does the Printer-MIB work on all printers?

The Printer-MIB (RFC 3805) is an IETF standard, so most network-capable printers from HP, Brother, Canon, Xerox, Lexmark, and others implement it — that's what makes it vendor-neutral. Coverage of individual leaves can vary slightly by model, so verify against your specific printer, but the core objects (supplies, page count, status) are widely and consistently supported.

### What OID is the printer page count?

The lifetime page (marker) count is prtMarkerLifeCount at 1.3.6.1.2.1.43.10.2.1.4. It's a monotonically increasing total, so graph its rate over time to see daily print volume and to predict consumable replacement. Combined with supply levels, it lets you forecast pages-per-cartridge and plan toner orders across the fleet.

### How do I compute toner percentage over SNMP?

There's no single "percent" OID — you derive it. Read the supply level (prtMarkerSuppliesLevel, .9) and divide by the supply's maximum capacity (prtMarkerSuppliesMaxCapacity, .8) at the same index, then multiply by 100. Always guard against the RFC-defined −2 (unknown) and −3 (some remaining) values so they don't produce a bogus negative percentage.
