Saving money on printer ink

[sommap]

I read that if you print most things in black instead of color, you obviously save on the color ink, which is more expensive.  I also read that if you print in draft style, it will save on the ink.  I do both of these things.  The funny part is that when I am printing on draft, my printer shoots the paper out so fast it keeps going until it hits a cabinet which is five feet away.  If I print on regular style, the paper sits in the printer when it has finished printing.
