Rhyas writes "Seems as though Lexmark has decided it wants all the pie when it comes to the printing world, as they are suing a company that does reselling of chips that allow third party toner cartridges to work in Lexmark printers. Cindy Cohn, an attorney at the Electronic Frontier Foundation, said she expected more cases like the one brought by Lexmark. 'We have long said that the DMCA's potential use as an anti-competitive tool has been great,' Cohn said. 'Now we're seeing it happen.'" The European Union is taking action against the practice of embedding chips in printer cartridges which make it difficult for third parties to sell refills.
