Invalid Printer Specified Error

Question

I have an application that allows the user to select the target printer from the list of available printers on the system.
The following code generates the list of printers from which they select:
Dim PrinterList As New List(Of String)
        Dim PrintServer = New LocalPrintServer
        Dim PrintQueues = PrintServer.GetPrintQueues(New EnumeratedPrintQueueTypes() {EnumeratedPrintQueueTypes.Connections, EnumeratedPrintQueueTypes.Local})
        For Each p In PrintQueues
            PrinterList.Add(p.FullName)
        Next
The selected value is saved. When I go to print, I use the following code to select the printer:
ClientInstructions.PrintOptions.PrinterName = My.Application.PrinterSettings.ActiveLetterheadPrinter

This works 90% of the time. I occasionally get the following error:
Error generated by: Print Client Instructions - Print Record Copy
Error Message:  Invalid printer specified.

When I use other redirectred printers, it works fine.
Any idea what I am doing wrong? Any thoughs are greatly appreciated.
