After installing Windows 10, or after updating Windows, your wireless printer may show as being offline in Windows (even though it is online), and you will be unable to print. Here’s a Windows-10 fix that worked for me:

  1. Go to Devices and Printers in Control Panel. One way to go there is to type “Devices and Printers” in the “ask me anything” field in left side of the taskbar, which is normally at the bottom of the screen. Then select Devices and Printers from the menu/choices that pop up.
  2. Right click on the printer that is shown as offline and select “printer properties” (not “properties”).
  3. Select the “Ports” tab.
  4. Press the “Configure Port” button.
  5. Uncheck the “SNMP Status Enabled” box.

This should resolve the problem and enable you to print.
