Web Printout problem

Hello I need some help I setup my Web application to print from a WebServer. I have setup the account so that it can print correctly. However, it can only print if the printer is connected to Win98 but if the printer is connected to Win2000/XP, it throws an error: Error in File xxx Request cancelled by the user. Here is my code to print over the web: Dim x As ReportDocument = New ReportDocument() x.PrintOptions.PrinterName = "xxx" x.PrintToPrinter(1, True, 1, 1) '(eror on this line) Please give me a solution thank u all
