It's weird. At the New line when it tries to enter printview it gives me this error: "Runtime Error 5918: The property or method is not available on this system."

I searched for this and this seems to be a problem that happened elsewhere also, when the same line of code was written:

I tried changing the line a bit, but still the same error: 
ActiveWindow.ActivePane.View.Type = WdViewType.wdPrintView
I also tried it on another computer where I work and it still gives me this. I am really confused about what this could be.
