I'm not 100% sure this will work so try it first:

'usage
For Each prn As String In PrinterSettings.InstalledPrinters
    Debug.WriteLine(String.Format("Is printer {0} online? {1}", prn, CheckPrinter(prn).ToString))
Next

'function to test printer status
Private Function CheckPrinter(ByVal printerName As String) As Boolean
    Try
        Dim printDocument As PrintDocument = New PrintDocument
        printDocument.PrinterSettings.PrinterName = printerName
        Return printDocument.PrinterSettings.IsValid
    Catch ex As System.Exception
        Return False
    End Try
End Function

As you use Vb.net I guess you are on a windows machine. Use your operating systems API. Like e.g. GetPrinterStatus.
