Too much lag for SNMP probably. Quickest solution/workaround is:
Start > Devices and Printers
right-click the printer and go to Printer properties
Ports > Configure Port
OK > OK
I am having the same problem with my Xerox Workcentre 6605 - for the past few days the printer is always 'offline'. Sometimes rebooting PC and printer works but often I have to remove the printer and re-install it. It is linked via wifi.
I looked at your suggested solution but when I get to Printer Properties>Ports>Configure Ports I get an error message:
'An error occureds during configuration. This operation is not supported'.
The printer is on the WSDF port.
My operating system is Windows 10
Can you provide any further suggestions to resolve the persistant offline issue?
Never use WSD, in the same place as the Configure port there is an option for Add Port.
Use that and just create a port using settings to match the screenshot.
