HP OfficeJet Pro 9720e SNMP not working

[Edward_S]

Hello,

I'm monitoring toner levels on all our network printers. Most of the printers are HP. We recently deployed an HP OfficeJet Pro 9720e printer, and I can't receive SNMP information from it. The SNMP is set correctly, screenshot attached. Printer is on the latest firmware.

Any idea why it's not working? All other network printers (different model) working fine with the same settings.

Hi @Edward_S , the log shows that the SNMP credentials are not correct: 

Scanning SNMP..
SNMP disabled or wrong community

Could you doublecheck that the SNMP account details are correct? 

Additionally, you are running an old Lansweeper version (v10.0.1.0). we recommend updating to the latest version, as there has been multiple SNMP enhancements and bug fixes since that version was released. You can find the update instructions in this article:
