WebService 调用打印机

         [WebMethod]
        public string PrintT()
        {
            System.Drawing.Printing.PrintDocument prnDocument = new System.Drawing.Printing.PrintDocument();
            prnDocument.PrinterSettings.PrinterName = @"\\192.168.0.110\PDFCreator";
            prnDocument.Print();
            return "打印成功";
        }

特别强调要指出 调用哪个台打印机
