Cannot access Universal Print Printer Registration API

[SongLei]

Hi,

I am trying to call the Printer Registration API (https://docs.microsoft.com/en-us/universal-print/hardware/universal-print-oem-printer-registration) by following the instruction (https://docs.microsoft.com/en-us/universal-print/hardware/universal-print-oem-app-registration). But we encountered an error, "The scople doesn't exist" (Please see the attachment).

My API permission list is also attached. (This account has the right to use Universal Print.)

I am not sure if our account is lack of some permission to access this API. Do I need to do some application for accessing the API?

Please give me some suggestions. Thank you in advance.

@SongLei, I'll follow up with you separately as there are a number of things to be aware of if you are building a printer to integrate with Universal Print, which are difficult to explain in a community post.

Thanks,

Jimmy
