works great, easy to set up, also works with google print I think it's a newer firmware than the others mentioned as the screens they reference no longer exist. Energy saving function, they have changes and they just work, they had no problems with falling asleep and not waking up, satisfied with the purchase on 3/18/2018 after a new firmware update, had to fix the deep sleep for printers mentioned by others, was able to set the parameter on on the Web Management page. Go to General Settings, then OK, Environment, then OK. worked great to deep sleep off SAVE.edit 6-2018 it sometimes had to be switched off to work quite annoying prints ok but I wouldn't buy it again
