Solution

The powerful FixedContentEditor allows you draw any element at the desired Position:

        public static System.Windows.Size pageSize = new System.Windows.Size(Unit.MmToDip(210), Telerik.Windows.Documents.Media.Unit.MmToDip(297));
        public static Padding pageMarginsValue = new Telerik.Windows.Documents.Primitives.Padding(
             Unit.MmToDip(20),//left
             Unit.MmToDip(0),//top
             Unit.MmToDip(0),//right
             Unit.MmToDip(0));//bottom
        public static double currentYposition = pageMarginsValue.Top;
        public static double currentXposition = pageMarginsValue.Left;
        public static double pageYLimit = pageSize.Height - pageMarginsValue.Bottom;
        public static double pageXLimit = pageSize.Width - pageMarginsValue.Right;
        static void Main(string[] args)
        {
            RadFixedDocument fixedDocument = new RadFixedDocument();
            DrawLogo(fixedDocument);
            DrawHeading(fixedDocument);
            DrawText(fixedDocument);
            PdfFormatProvider provider = new PdfFormatProvider();
            string outputFilePath = @"..\..\sample.pdf";
            File.Delete(outputFilePath);
            using (Stream output = File.OpenWrite(outputFilePath))
            {
                provider.Export(fixedDocument, output);
            }
            Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true }); 
        }
