Writing a document in TIFF format using only native .NET namespaces

I have a VB.Net program which uses a third-party "print to file" object to create some TIFF files.  This object is failing randomly (apparently randomly that is).  Every so often it just prints a blank document (no errors, it's just blank).  If I recreate the scenario exactly, it will run fine...usually.  Bottom line is that I want to abandon this 3rd party tool and just use pure .NET to do the job.  I don't know how though.  

I've posted the essential code below of how I use this defective "ImageConverter" object.  How can I swap this out for pure .NET and still get a TIFF image (yes, it must be a TIFF file)?

Imports System.Drawing.Printing

Dim WithEvents PrintDoc As New System.Drawing.Printing.PrintDocument
Dim ImageConverter As New badPDFPrinter

With ImageConverter
     .OutputFormat = badPDFOutputFormatEnum.TIFFG32d
     .Settings.OpenDocumentAfterCreation = False
     .ApplySettingsBeforePrint()
End With

PrintDoc.PrinterSettings.PrinterName = ImageConverter.PrinterName
PrintDoc.Print()
ImageConverter.WaitUntilDocumentIsPrinted()  'prevents the biopdf user interface from launching
