PrintAsync prints blank page - WinForms VB.NET

[Desz5]

I have a question and i hope someone can help me:)
I load a page containing a label PDF and i would like to print it using the following command:

await WebView_Browser2.CoreWebView2.PrintAsync(PrintSettings)

I have the PrintSettings set to a number of Copies and PrinterName.
After the page is fully loaded i wait an additional 4/5 seconds to ensure everything is completely loaded.
But it prints a blank page/labels everytime.
The number of Copies work and it prints on the correct printer.
But everything is blank.
When trying a different printer it's the same issue, the number of copies work and the other printer, but still blank labels are printed, why?
When printing the page normally it prints correctly, also with ctrl+p and with await WebView_Browser2.CoreWebView2.ExecuteScriptAsync("window.print();")
When looking at the printerqueue the document when normal printed is about 8 kb, when using PrintAsync the document is 143 bytes, why?
Why wont it work with PrintAsync?
Is there something i'm forgetting or is it a bug?
Thank you!

I see that it is a bug, same as this:
#1938

@Desz5 Current PrintAsync and PrintToPDFAsync doesn't support printing a PDF. I've added this bug to our backlog to correctly print PDFs. Thanks!

@monica-ch Thank you!

@monica-ch Is this something that will be fixed in the latest webview2 release?

@Desz5 We are planning to investigate this in next couple of sprints. I'll update the thread when the fix is available.

This also occurs for c# (since the title says VB.Net).

@Desz5 This is fixed in WebView2 runtimes 112.0.1675.0+. Please test using edge canary channel and let us know if you have questions.
