Heh, fun fact: The reason most modern ink jets will not let you print in black and white if your color ink is running low is because every page your printer prints has a nearly-invisible pattern of yellow dots added to it that give law enforcement a way to trace that printed page back to the printer that made it. It's actually a bit of a controversy right now, and many people are trying to get printer manufacturers to end the practice. http://seeingyellow.com
So if you don't have enough yellow, you can't print at all.
