The conflict is in the IP addresses being given.
Disable DHCP on the WAP11, let it pull addresses from whatever DHCP server sits behind it.
Give the WAP11 a non-conflicting (with the DHCP, but same subnet) a static address. Say, 182.168.1.9
Do the same for the print server, but a different static IP: say 192.168.1.8
Reboot all devices, starting with the router; then the WAP11, then the print device.
