How to print a pdf file directly to printer(silent printing) without using tools like adobe?

Question

Hi,

I have an invoice pdf file in my local file system. I need to directly print it without showing any preview or dialog box(silent printing).
Note: Without using tools like adobe reader.

Thanks.

Answer 1

Without any external tool, one of the ways is with Windows.Data.Pdf (references to Windows.winmd and System.Runtime.WindowsRuntime.dll for WPF or Winforms), by converting each PDF page into an image (I tested with a BitmapImage for example, from PdfPage.RenderToStreamAsync),
then you can print each image silently on a printer with PrintDialog.PrintVisual or other method

I used FreeSpire.PDF in .NET MAUI on Windows, I don't see any reason why it wouldn't work in WPF. Details here: [http://billreiss.com/2023/12/01/printing-a-pdf-from-net-maui-windows-silently/]
