    You should not need to modify your printer configuration, DHCP is enough.

    Can you try to ping your printer from a wireless endpoint?  Also check if your wireless blocks LAN to WLAN broadcast/multicast.

    I have an RT-AC5300 running the wireless network.  I don't see an exact match to Lan to WLAN broadcast/multicast.  It does have Set AP Isolated which prevents computers from talking to each other.  That is Disabled.

    Testing from in the router I can ping the gateway but not other devices downstream in the system, such as the printer.

    Can you the router reach your AP?  and AP is in bridge mode?  try to arp for the printer and see if you get something.  If not, then likely the AP is doing something

    if you have a pc or Linux, you can type "arp [printer IP]" and see if it will show up.  If it doesn't, you have an issue with your network segments.  You will need to double-check how your printer is connected to the main network, and make sure there is no NAT in between.
