It is well-documented that ink is not required in order to scan or to fax a document...
The reason Good will never prevail over Evil in this world is that Good is required to document shit like this, whereas Evil can get miles ahead being assholes in the time it takes to do that.
Ecotanks ftw. Sure they are slightly slower and when the paper gets damp the ink smears but for the price of the ink I'll take it. I bought a 3 pack of black ink 3 years ago and to this day only 1 bottle has been used.
