If you are seeing this error, that means SNMP info was scanned for the printer at some point, but can now no longer be accessed. Please contact support@lansweeper.com and provide us with screenshots of:
- One problem printer's Lansweeper webpage.
- A connection test performed to the printer using the DeviceTester.exe: http://download.lansweeper.com/tools50/DeviceTester.exe
Perform the test on your Lansweeper server, connecting to the printer's IP address, and show us the entire test window.
