1. Lansweeper doesn't create asset pages for local printers. As they don't have a network interface, the toner level of these printers can't be scanned. Local printers are visible on the asset pages of the computers they are connected to under tab
Config\Devices\Printer2. The
lastchanged field refers to the date when information about toner data was last updated by Lansweeper. That means it is the last date when Lansweeper scanned this printer and found new information about it. The date of last cartridge change isn't being scanned. You could use a custom field for this. Under
Configuration\Asset pages, section
Asset Custom Fields, choose a field, give it a title and change it's type to "Date".
