HP Printers don't run Oracle's (Sun) JVM (Score 4, Informative)

The article leads the reader to believe that the VM running on HP LaserJet printer is an old version of Sun's -- now Oracle -- JVM. That's no true. HP Printers run ChaiVM, a clean-room implementation written based on the published specification. Moreover HP has historically recommended their customers to NOT expose printers to the public Internet. The embedded web server is an administration tool, not a fully-fledged HTTP server, and was not designed to be used that way.
