Crystal Report in WinXP

Hello Everybody

I Used Crystal Report in Win 98 and noe I want to change my platform to WinXP.

my program was something like this.

  Dim P As Printer, L As Printer
  For Each P In Printers
 if someconditionoccurs then
        L.PrinterDriver = P.DriverName
        L.PrinterName = P.DeviceName
        L.PrinterPort = P.Port
 endif


and somewhere else in my program

     CR1.Destination = crptToPrinter
     CR1.PrinterDriver = L.PrinterDriver
     CR1.PrinterName = L.PrinterName
     CR1.PrinterPort = L.PrinterPort
     CR1.Action = 1

this worked in Win98 but now in WinXP I have two problems.
1: Driver for all printers is "winspool"
2: There is something wrong with name of printers
    as after calling "Action" error code 20530 with message
"Invalid printer specified" is shown.

Can anybody help me? I use shared printers and I dont know how can I manage it.

Thanks for your attention.
