True, printer ink is mass production so it should be much cheaper.

Printing with blood is more of a niche market right now.

Hussein used to do that, but it never went mainstream [http://en.wikipedia.org/wiki/Blood_Quran]

KISS did it as well. http://www.snopes.com/music/artists/kissblood.asp

And The Flaming Lips. http://www.rollingstone.com/music/news/wayne-coyne-makes-pos...

Human blood is far more mass produced than printer ink. There are currently about 7 billion mostly independently owned and operated production facilities. The problem is the supply lines and market prices. Distribution of the surplus also tends to be fairly shitty.

(that last bit was a poop joke, not a statement about my opinions on the subject of donated blood distribution)

I thought the joke was about the medical practice of bleeding.

If someone has too much blood does it really get disposed of that way?

That's interesting, I didn't know that.

If my memory serves, it's more a disposal for old damaged red blood cells than just disposal of excess.
