如何告诉打印机打印灰度或彩色内容

Question

I have this line of codes that will tell the printer to print a document. But it will only print colored content.

word = Dispatch("Word.Application")
word.Documents.Open(self.filePath)
word.ActiveDocument.PrintOut()
word.ActiveDocument.Close()
word.Quit()

What I want is to tell the printer to print grayscale content. Is there any possible solution for this?

Q: How to tell the printer to print grayscale or colored content?

• Short Answer: :

  You have to talk to the relevant printer driver, which is completely platform- and API-specific.

• Longer Answer:

  The snippet you showed, word = Dispatch("Word.Application") , is using a Python wrapper to Microsoft Com/ActiveX . Specifically, to the MS-Word COM/ActiveX component (which was presumably registered on your PC when you installed MS-Word).

  So all you have to do is look at the options provided by "Word.Application":

Be advised, you might also have to play around with "Printer Device Settings", for example:
