Today my Epson printer stopped working. I have the tool they provide to reset the ink pad counter but it simply reports network error after network error trying to connect to the Epson server. Since its Christmas eve and I need to print some gifts for my kids I was totally hooped until I found you guys. I just want to thank you for doing what Epson was unable to do. They suck, you rock!

Thank you. for the program. It worked on TX106 printer. Reset waste ink counter in few minutes. Not go to epson customer service. Good.

Awesome. I made a mistake ordering 2 codes (I needed just 1). They called me (I'm in Italy) to ask if it was an erroneous "double click"...and they deleted the second order. I still can't believe it. That's PURE QUALITY. (Of course the whole thing works and the printer is doing his work). THANX!
