Issue with Canon MFNP Port and Wi-Fi Direct Compatibility on MF443dw

Hi,Due to a Windows update in 2025, there is an issue with unintended printing for printers connected via USB(https://learn.microsoft.com/en-us/windows/release-health/status-windows-10-22H2#3495msgdesc - Is there any solution to this problem? ).In the institution I work for, I disconnected USB connections of computers without network capability and connected them via Wi-Fi Direct. I installed the relevant driver for the Canon MF443dw printer using the Wi-Fi Direct connection. The issue is that I cannot print or scan through the Canon MFNP port. When I switch the ports to WSD, I can print, but I cannot scan through the WSD port using the MF Scan Utility application. My question is: Is CNMFNP incompatible with Wi-Fi Direct? If it is incompatible, how can I perform scanning in this situation?

Greetings,

Why struggle. Uninstall the update. Its a preview update, not critical. MS will eventually address.
