The IP assignment would come from the main router as the EAP just passes that request through it being an AP.

I would check the printer network settings, typically you want it set for DHCP so it will automatically get an IP like your other devices do. If the network has to be set statically look at your other connected devices to see what network information they get, copy everything except in the last part of the IP, change that number. So for example, if your iPad gets an IP of 192.168.0.110, make the IP of the printer 192.168.0.250, and everything else the same.
