UWP to print without Print preview

In my UWP application, I wanted to print a document without showing the print UI. Normally we use PrintManager.ShowPrintUIAsync()
But I wanted to print without showing the UI. In my Research, I found that there's no such thing in UWP to print directly without showing Preview. But it can be done through FullTrustProces Launcher (or) Brokered Component. I am unaware of both of this 2 processes. Can someone tell me the way to use them in detail or any other way to get print without showing the Preview or sending stream directly to the Printer?

Edit1: Someone tageed it as a duplicate, so i explained the difference between the 2 questions. It's not the duplicate of that question. My question clearly asks which process shall i use whether the FullTrustProcess Launcher or Brokered Component. The question that person tagged is asking whether there's a way to print silently. But my question is which method is best.

No matter FullTrustProces Launcher (or) Brokered Component technology, they all call win32 APIs to achieve the silent print.

For the FullTrustProces Launcher, it actually is putting a win32 process in your UWP app package. The win32 process could be console application, Windows Forms app etc. Stefan has replied a similar thread. On that thread, Stefan has explained and provided a simple code sample, please check it.

You could also refer to this blog Desktop Bridge – The Migrate phase: invoking a Win32 process from a UWP app for more details.

For the Brokered Windows Runtime Components, it makes side-loaded Universal Windows Platform apps to interoperate with desktop processes outside of the app container possible. Please see Brokered Windows Runtime Components for a side-loaded UWP app for more details.
