Does the Aspose.PDF support printing a doc/pdf for customed color or white-black mode?

That’s great! I’ll take a try.
And else, Does your PDF.dll supports this feature? If no, hope the Pdf.dll support it.

@ducaisoft I will move your question to Aspose.PDF forum. My colleagues from Aspose.PDF team will help you shortly.
