You don't convert Crystal Reports to plain text (which what I think you mean by notepad). Crystal has the ability to send its output to the printer via the ReportDocument.
report.PrintOptions.PrinterName = printerName;
report.PrintToPrinter(1, true, 0, 0);
If you are attempting to print server side from ASP.NET, you register your network printer as a local printer entry on each web server. This will allow your network printer to be visible and accessible in an ASP.NET application.
