printersettings conversion to vb.net

I found this code which is what I need for my program.  I tried to convert it myself, but I get an error on
fi.SetValue(PD.PrinterSettings, outname)
It says object reference not set to an instance of an object.

Here is the original code:
System.Type type = typeof(PrinterSettings);
this.PrinterSettings.PrintToFile = true;
FieldInfo outputPort = type.GetField("outputPort",
BindingFlags.NonPublic | BindingFlags.Instance);
outputPort.SetValue(this.PrinterSettings,"FILE:");

Here is what I converted it to:
Dim PD As New Printing.PrintDocument
       
Dim fi As System.Reflection.FieldInfo
Dim outname As New Object

PD.PrinterSettings.PrintToFile = True
fi = PD.PrinterSettings.GetType().GetField("outputport", Reflection.BindingFlags.Instance)

outname = "C:\jimc.ps"
fi.SetValue(PD.PrinterSettings, outname)  "I get the error on this line"

PD.Print()

Can someone help me with this conversion?
