After enabling Windows protected print mode I am no longer able to add a printer queue programmatically using the Win32 API nor using Powershell. Windows protected print mode requires me to use the built-in driver called Microsoft IPP Class Driver. The following Powershell command works when Windows protected print mode is disabled, but the question is, how can I install a printer queue with Windows protected print mode enabled (using the Win32 API or Powershell)?
Add-Printer -Name "My Printer Name"
-PortName "http://printer-hostname:631/ipp/print"
-DriverName "Microsoft IPP Class Driver"
I don't actually expect this to work with this new Windows feature. Calling into printui might actually kick in the Plug and Play aspect though. I am pretty confident you are the first person to even try this.

This works:
Add-Printer -IppURL http://printer-hostname:631/ipp/print
Anyone find out how to do it via win32 API?
Yes, this is working. Thank you very much!
Is it possible to do the same using the Win32 API?

i use the same method to add printers using the IPP class driver. by default you don't set a printername. you can rename it afterwards. the IPP class driver is automatically selected by the OS, so you do not need to specify a driver. This will work with WPP. If your printer manufacturer offers a Printer Support Application you will also see that appear automatically, provided your users have access to the MS store.
If you want encryption:
Add-Printer -IppURL ipps://printer-hostname:443/ipp/print
Have you tried using printui.exe for this? Printui /? Will give you additional parameters. The printer must be turned on and Mopria compliant in order to be added when WPP is enabled. If that endpoint is not hardware, then you can't use printui or PowerShell
Hello,
You can find this in document: https://learn.microsoft.com/en-us/windows-hardware/drivers/print/windows-protected-print-mode#windows-protected-print-mode-device-compatibility
upon enabling Windows protected print mode, printers that use third–party drivers are uninstalled.
The print driver is deleted from the print driver store, and it can't be used while Windows protected print mode is active.

Hello,
I already know that third-party drivers can't be used in WPP-mode. What I'm asking is how to install a printer queue using an IPP-port and the Microsoft IPP Class Driver either using Win32 or Powershell. This doesn't seem to be possible anymore.
