Printing Word Document

Here is the solution: PaperSource tray2; PrintDocument pd = new PrintDocument(); for (int j = 0; j < pd.PrinterSettings.PaperSources.Count; j++) { if (pd.PrinterSettings.PaperSources[j].SourceName.Trim() == "Tray 2") { tray2 = pd.PrinterSettings.PaperSources[j]; } } int rawKind = Convert.ToInt32(tray2.GetType().GetField("kind", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).GetValue(tray2)); oWordDoc.PageSetup.FirstPageTray = (Word.WdPaperTray)rawKind; oWordApp.ActivePrinter = printername; oWordApp.Visible = false; oWordApp.PrintOut(ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
