That figure cannot be right. Does it have gold in it? Or maybe 
someone is figuring based on $50+ ink cartridges? That would be 200 
cartridges and may make some sense. Maybe they should move away from 
personal inkjet printers and use laser or possibly negotiate a better 
purchasing contract on their cartridges or start using refillables.

I did a bit of calculation. One website says an HP88 model takes 
47.5ml of ink. That equates to 1.6 ounces. There are 128 ounces in a gallon.
There is a value site where you can pay $60 for the 4 cartridge pack. 
That's. $27.50/ounce times 128 = $4800/gallon.

Even the manufacturers price is only $71 for each individual 
cartridge in total. $44.37/ounce times 128 = $5680/gallon

Our truest response to the irrationality of the world is to paint or 
sing or write, for only in such response do we find truth.
