No problem here. Check your wireless settings.
Try forgetting your previous connection and connect your iOS 8 device to the printer as if it was a new iPhone/iPad.
After upgrading to iOS 8, I'm no longer able to print using my AirPrint capable printer (an Epson WF-3520). Has anyone had trouble with AirPrint after upgrading?
I have been having a similar issue with my Epson WF-3540. I am not sure why but if I unplug the router for a minute or 2 then when it starts back up I can print from my iPad and iPhone with IOS 8 for awhile. Sometimes days. But I may have to re-boot the router again. For me it appears to be a Netgear problem.
