Example: Monitoring Network Printer Toner Levels
To avoid running out of printer ink in the middle of print jobs, or wasting toner by switching toner cartridges before they are empty, through WhatsUp Gold you can create a custom SNMP active monitor that notifies you when toner levels are low.

- Enter a and for the monitor. For example, TonerMonitor and Toner monitor for the Hewlett Packard LaserJet 4050N.
