How often does the Toner Level update?
PaperCut makes sure to routinely query a printer or copier to determine its toner levels. The frequency of this can be modified to a degree.
A toner level update is requested:
- When a print job completes (and something printed)
- When a copy job completes (and paper was output)
- Overnight (during the "daily maintenance tasks")
- When manually requesting it via the printer's page in the admin interface
- When a print queue is first created / set up
However, it is skipped if:
- Toner checks are globally disabled
- The device's network address ("physical identifier") is not known
- If toner was checked recently (controlled by the advanced config option "toner.minimum-check-period-mins")
The default value for "toner.minimum-check-period-mins" is 240 minutes (4 hours).
In summary, while devices are in use the toner levels are updated every 4 hours. If a device has not been used for at least 4 hours its toner levels will be updated either overnight or when it is next used.

How much bandwidth does an update use?
PaperCut uses SNMP to poll the print device, this is a very well known and well documented protocol. You can expect a query and response to only take a few KiloBytes (KB) of bandwidth every few hours. It's what we like to call a drop in the ocean!
