jkmozzz 0 Report post Posted January 24 Hello, I'm brand new to this so I would like to know, is the activation key good only once? I have an Epson XP-1500. How is the reliability of this firmware with my printer? Can you reverse the firmware back to Epson if needed? Thank you, John Share this post Link to post Share on other sites
