Joe recently had a firmware update, and Epson killed the ability for him to use third-party ink cartridges. Leo hates that and says it's anti-competitive. It also wreaks of industrial sabotage and begs the question: if they can do that, do you really own your printer?
If accurate, Leo finds this a disappointing development because he's always considered Epson one of the "good guys." And he hates copy protection.
If you like Epson though, the EcoTank line gives you enough ink so you don't need cartridges.
