@argen96 I've now got it working and everything is working very well. The only problem is that the box just crashes in the middle of printing. Sometimes it prints for more than 15 hours without problems and sometimes it crashes after 8 hours. That means the printer just stops and nothing happens anymore. The tv box can no longer be reached via the Internet either. Can I see a log somewhere of what exactly is happening?I took this image, is that the right one?

Does the system perhaps have a standby mode and that is where the problem is?
