  Thank You. I had just bought a new printer and Epson asked to update the firmware...unfortunately in the middle of the update my power shut off. I thought for sure I had deep sixed my brand new device. Even on the Epson website I could not find a manual firmware recover for my printer and OS version...others printers yes, but not this one. I found you website and thought I'd give it a try. Horray, My printer is back working again. While I am not happy to have to pay someone else for something that Epson should have given for free, your price was with-in reason and your software was easy to use.

  Much easier then I had expected. Downloaded the program, purchased the key, switch off and on the printer and that was it! The printer works again.

  This was awesome. I was skeptical at first, but the program worked beautifully. Thank you for helping me, where Epson couldn\'t. I truly appreciate it! Great investment, happy camper.
