I use an Epson ET-2550 & ET-2750. They use an internal "maintenance box" to dump ink. It's easy to clean, but needs to be reset after cleaning. Was recommended this software by this video which specifically uses your software to reset the ET-2750 maintenance box counter. But I can't find ET-2750 in the license list.
Is there any chance you'll start supporting ET-2750 & ET-2550 again?
