Solution

RadRichTextEditor supports importing the content of different document types like DOCX, XAML, HTML, RTF, Plain text. To import a document you have to use a specific class that implements the IDocumentFormatProvider. The supported document providers in RadRichTextEditor are listed here. Once a document is imported in RadRichTextEditor, you can use its printing functionality.

Silent Printing of Word and HTML documents

namespace ConsoleApplicationSilentPrintRTE
{
    class Program
    {
        static void Main(string[] args)
        {
            PrintWordDocument(@"..\..\Sample.docx");
            PrintHtmlDocument(@"..\..\Sample.html");
        }

        private static void PrintHtmlDocument(string fileName)
        {
            Telerik.WinControls.UI.RadRichTextEditor radRichTextEditor1 = new RadRichTextEditor();
            Telerik.WinForms.Documents.FormatProviders.Html.HtmlFormatProvider provider = new HtmlFormatProvider();
            using (System.IO.FileStream inputStream = File.OpenRead(fileName))
            {
                radRichTextEditor1.Document = provider.Import(inputStream);
            }
            radRichTextEditor1.LoadElementTree();
            radRichTextEditor1.Print();
        }

        private static void PrintWordDocument(string fileName)
        {
            Telerik.WinControls.UI.RadRichTextEditor radRichTextEditor1 = new RadRichTextEditor();
            Telerik.WinForms.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider provider = new DocxFormatProvider();
            using (System.IO.FileStream inputStream = File.OpenRead(fileName))
            {
                radRichTextEditor1.Document = provider.Import(inputStream);
            }
            radRichTextEditor1.LoadElementTree();
            radRichTextEditor1.Print();
        }
    }
}

Module Module1

    Sub Main()
        PrintWordDocument("..\..\Sample.docx")
        PrintHtmlDocument("..\..\Sample.html")
    End Sub
    Private Sub PrintHtmlDocument(ByVal fileName As String)
        Dim radRichTextEditor1 As Telerik.WinControls.UI.RadRichTextEditor = New RadRichTextEditor()
        Dim provider As Telerik.WinForms.Documents.FormatProviders.Html.HtmlFormatProvider = New HtmlFormatProvider()

        Using inputStream As System.IO.FileStream = File.OpenRead(fileName)
            radRichTextEditor1.Document = provider.Import(inputStream)
        End Using

        radRichTextEditor1.LoadElementTree()
        radRichTextEditor1.Print()
    End Sub

    Private Sub PrintWordDocument(ByVal fileName As String)
        Dim radRichTextEditor1 As Telerik.WinControls.UI.RadRichTextEditor = New RadRichTextEditor()
        Dim provider As Telerik.WinForms.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider = New DocxFormatProvider()

        Using inputStream As System.IO.FileStream = File.OpenRead(fileName)
            radRichTextEditor1.Document = provider.Import(inputStream)
        End Using

        radRichTextEditor1.LoadElementTree()
        radRichTextEditor1.Print()
    End Sub

End Module


The above approach can be followed with the rest of the document providers that RadRichTextEditor offers.
