I have long known printer ink was a scam, maybe some of my dear friends that work for HP could explain the ink usage above. In particular:

1) Why does pure black printing use magenta?
2) How can one page take yellow from 80% to 13%. (Note that the page in question was not a photo of big bird waving a Boa Vista flag while eating a banana just after being diagnosed with hepatitis.)
3) How does ink suddenly go up by 3%?
4) Why don't you document the MIB for ink? Why must I poke at the printer for a long time, then wait for the ink to drop off of 100% in order to determine what color it is?

Interesting factoid: if I pull a nosehair out of my left nostril, it makes me sneeze. I just thought you would want to know.

...and the pile is back. The circle of life is completed.

magically, the pile disappears.

Big pile of crap.
