Printing in Grayscale in .NET

[WFM]

I would like to print in one bit but I guess that grayscale is the closest. What I using is
Dim PDFPrinter As String = "My Converter"
Dim CDI As CDIntf.CDIntfControl = New CDIntf.CDIntfControl
CDI.DriverInit(PDFPrinter)
' CDI.SetPrinterParamString()
CDI.FileNameOptions = 80003
'CDI.FileNameOptions = 3
CDI.EnablePrinter("My Company",...EF25")
'CDI.BatchConvert("C:\Temp\input\*.htm")
CDI.SetPrinterParamString("File Name", sOut)
If I use the Options=3 it works fine-- if I use the Options=80003 then the image is an "Unrecognizable Image Format". Is there something else that I need to do using the .Net Dll in VS2003/5? Is this supported in the .Net version?

Thanks,

Hello,

Printing in gray scale shouldn't cause a problem. I suggest that you try using the latest version 2.50 of the driver to check if this issue presists.
