what if you dont have the exact printer colors? mine ran out and i dont want to get a refil

I think the poor English in the original post is too confusing... Which of these is your situation:

1) I ran out of color ink and want to print in black AND white (grayscale)
2) I have all my ink but I only want to print using black ink (grayscale)
3) I have all my ink but I want to print inverted colors on dark paper (print on black paper in white ink)

Of those three only #2 can be solved without buying a new printer/toner, and that one is as easy as clicking the printer properties when you go to print.
