I'm trying to find out how to ask the computer how much ink is left in the printer cartridges. Maybe it will tell me if theri empty or not.

What make/model of printer?
If it is an HP Deskjet 670C, those printers didn't have the capability of keeping track of ink usage... they're simply too old. It's amazing you can still get cartridges if that is the printer you have.
