Well, I've used multiple Epson and even a HP WiFi printer. And all of them worked perfectly. Way better than on Windows. In the worst cases, I had to choose the driver from a list and that's it. In some instances, I even have ink level indicators, and options to clean the printer. It's really cool
Not for now. The project is still in very early stages. Will probably open source it once the first beta comes out. But if enough people want it, I can open source it now
