[Feature]: Result of calling ShowPrintUI

Describe the feature/enhancement you need

Once the print preview window has been called, there is no way to know whether it was completed by clicking the Print button or by clicking the Cancel button.
I would like to have the following two options:

1. ShowPrintUI should show a modal preview window.
2. ShowPrintUI should return a True/False value indicating whether the document was sent to print or not.

The scenario/use case where you would use this feature

1. Preview a specific document.
2. If the user has sent the document to printer (pressed the Print button), then add a mark to the system that the document has been printed, print the accompanying documents and send an email with a notification to the Client.
3. If the user has not sent the document to print (pressed the Cancel button or closed the window in another way), then do nothing.

How important is this request to you?

Impactful. My app's user experience would be significantly compromised without it.

Suggested implementation

No response

What does your app do? Is there a pending deadline for this request?

Our application uses WebView2 to print various medical reports.

Start by reviewing the ShowPrintUI API and the existing WebView2 printing behavior described in this issue. Determine how modal completion and cancellation are currently exposed, then define an API result that distinguishes printing from cancellation or window closure; the work is done when both requested behaviors are supported and documented.
