Description: Hewlett-Packard LaserJet 2300 series printer MIB defining SNMP objects for consumable levels, paper handling, and device alerts.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is LJ2300-MIB?

LJ2300-MIB is Hewlett-Packard's private MIB for the LaserJet 2300 series monochrome laser printer, covering device-specific objects beyond the standard Printer MIB for consumables, paper handling, control panel, and diagnostics. It exposes self-test and diagnostic controls (self-test, print-internal-page, perm-store-init-occurred), control-panel status objects such as button-press events and display contents with a CRC/change-counter (control-panel-display-contents-crc, control-panel-display-contents-change-counter), and status message lines (background-status-msg-line1-part1/background-status-msg-line2-part1) reflecting the printer's current activity or error condition. Its monitoring emphasis is squarely on device software/hardware status - reading the live status-message lines to see conditions like out-of-paper or low-toner, watching control-panel interaction events, and using self-test/print-internal-page to verify the print engine and formatter are functioning, plus power-management state via the energy-star object. It works alongside and extends the standard Printer-MIB and Host Resources MIB, layering HP-specific PML (Printer Management Language)-derived objects (via netPMLmgmt) on top. It is deployed wherever HP LaserJet 2300 printers are managed in office/enterprise print-fleet monitoring via SNMP. Engineers can download the LJ2300-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LJ2300-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • HP LaserJet 2300 series printers

Monitoring Examples

A print-fleet monitoring tool would poll background-status-msg-line1-part1/background-status-msg-line2-part1 to display the printer's current human-readable status (e.g., a jam or low-toner message) without needing to interpret raw Printer-MIB alert codes. control-panel-display-contents-crc changing between polls indicates the front-panel display content has changed, useful for detecting an error screen being shown. Triggering self-test or print-internal-page remotely lets a technician verify the print engine still produces output when a print job otherwise seems to hang.

What Can Be Monitored

  • printer status message text
  • control panel display contents/changes
  • control panel button presses
  • self-test/internal page print results
  • energy-star power state
OIDs
