Hello - just great! Greetings from Germany - Es funktioniert auch mit dem Epson PX810FW perfekt - einfach hinten per USB anschließen und das kostenlose Programm laden. Wenn der Drucker gefunden wurde, den Reset Key online per PayPal kaufen. Habe sofot den Key per E-Mail bekommen. Jetzt noch 3 Klicks und der Drucker ist wieder wie neu.... Danke und Gruß
