Worked hassle free with my Epson XP-55 . I am very thankful that you provide the SW tool also for Linux as I have gone Microsoft-free at home. It's cool that you provide a trial license to check out, whether the counter reset works in your setup (I admit I was sceptical). It worked for me and I immediatly ordered the full license. The good thing is: as it is pure SW, it works also on weekends, when you need to print urgently and that stupid printer decided to not let you print any more!

Hello, you guys are legends for providing this service. It's fucking rediculous customers have to use hacked firmware just to use their own fucking printers. Thanks again.

I always bought the key and it arrived correctly, but unfortunately in my last 3 purchases, the key did not arrive. I already sent an email to support with the order number with the problem, they told me that everything was resolved, but nothing was resolved, and I still don't have the key. very bad and slow customer support, it took almost 2 days for useless response.
