You can use ShellExecute(Ex) with the print verb to invoke the same operation as if you right click a file and choose print.

It will show window to select printer and configuration, right?

What I want to do is:

I have printer name and path of the PDF file. I want to programmatically (silently) print the PDF without showing any window.

Maybe - it'll depend on the behaviour of the registered application.

You can convert the PDF to bitmaps with Windows.Data.Pdf

and then print the bitmaps silently

I had posted a sample in C#/WPF that can be adapted in C++ :

Was able to get PdfDocument and PdfPage. That is fine.

However the DrawingVisual class used in that code is not available for my WinRT app.

You get IRandomAccessStream from PdfPage.RenderToStreamAsync that you can convert to BitmapImage (like in some samples like https://github.com/microsoft/Windows-universal-samples/blob/bb470280e493a888d98ac367edf3b85f8c053c4f/Samples/PdfDocument/cpp/Scenario1_Render.xaml.cpp#L141)

or call CreateStreamOverRandomAccessStream to get IStream (then some APIs like GdipCreateBitmapFromStream to get a GDI+ bitmap from the stream)
