Windows 11 25H2 Canon printers no longer redirect through RDP to Windows Server 2019

Hi David E. Kerwin, CFA,

I’ve reviewed the details you shared about installing the Canon Generic Plus UFR II V340 driver with pnputil and the fact that it still doesn’t appear in redirected printers during the RDP session. That indicates the driver package is present on the host, but Windows 11 25H2 is not mapping it correctly through the redirection layer.

Please double‑check the Group Policy on the Server 2019 host under Computer Configuration= > Administrative Templates => Windows Components => Remote Desktop Services => Remote Desktop Session Host => Printer Redirection. Make sure “Redirect only default client printer” is set to Disabled. Also confirm in the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services that there is no value like DisablePrinterRedir set to 1.

It’s worth trying to install the Canon driver using the full setup package rather than pnputil, since the setup registers additional components that RDP redirection depends on. If you still don’t see the printer, temporarily enable Easy Print to verify that redirection works in principle, then disable it again and retest with the Canon driver.

Given that your Dell XPS test shows similar behavior, this strongly suggests a change in Windows 11 25H2 affecting Canon redirection. I recommend monitoring Canon’s support site and Microsoft’s update catalog for a driver update or hotfix. If the issue persists after these checks, opening a support case with Microsoft would be the most reliable way to get an official patch for RDP printer redirection in this build.

Hi David,

This behavior is typically caused by a driver isolation or redirection mismatch introduced in recent Windows 11 updates where third-party Version 3 drivers like the Canon Generic Plus UFR II V340 are blocked from redirecting, while Microsoft IPP Class Driver redirection fails due to fallback rendering policies on Windows Server 2019.

To resolve this, open Local Group Policy Editor on your Windows Server 2019 RDS host by running gpedit.msc and navigate to Computer Configuration => Administrative Templates => Windows Components => Remote Desktop Services => Remote Desktop Session Host => Printer Redirection. Open the policy Use Remote Desktop Easy Print printer driver first, set it to Disabled, and run gpupdate /force in Command Prompt to force the session host to use matching vendor drivers rather than falling back to Easy Print IPP drivers. Next, install the exact same Canon Generic Plus UFR II V340 driver package directly onto the Windows Server 2019 host so both client and server share identical driver definitions. Finally, if redirection is still restricted by driver isolation, open regedit on the Windows 11 client, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services, create a DWORD value named DisableFDORedir and set it to 0, then restart your RDP session.

If this solution helps resolve your issue, please accept this answer so other community members can benefit from it as well.
