ASP.NET C#

well you can just save the page as HTM which Winword knows howto open

and for the print issue you can ues this code:

          Word.Document oWordDoc = new Word.Document();

            Object copies = "1"; 
             Object pages = ""; 
             Object range = Word.WdPrintOutRange.wdPrintAllDocument; 
             Object items = Word.WdPrintOutItem.wdPrintDocumentContent; 
             Object pageType = Word.WdPrintOutPages.wdPrintAllPages; 
             Object oTrue = true; 
             Object oFalse = false; 
             Object oTemplatePath = templateFullPath; 
             oWord.Visible = true;

            oWordDoc = oWord.Documents.Add(ref oTemplatePath, ref 
 oMissing, ref oMissing, ref oMissing);

            foreach (Word.Field mergeField in oWordDoc.Fields) 
             { 
                 Word.Range rngFieldCode = mergeField.Code; 
                 String fieldText = rngFieldCode.Text;

                if (fieldText.StartsWith(" MERGEFIELD")) 
                 { 
                     Int32 endMerge = fieldText.IndexOf("\\"); 
                     Int32 fieldNameLength = fieldText.Length - 
 endMerge; 
                     String fieldName = fieldText.Substring(11, 
 endMerge - 11); 
                     fieldName = fieldName.Trim();

                    mergeField.Select();

oWord.Selection.TypeText(letterData[fieldName].ToString()); 
                 } 
             } 
             oWord.ActiveDocument.PrintOut( 
                 ref oTrue, ref oFalse, ref range, ref oMissing, ref 
 oMissing, ref oMissing, 
                 ref items, ref copies, ref pages, ref pageType, ref 
 oFalse, ref oTrue, 
                 ref oMissing, ref oFalse, ref oMissing, ref oMissing, 
 ref oMissing, ref oMissing);

            oWord.Quit(ref oSave, ref oMissing, ref oMissing);
