Your printer used to work fine. Now your phone can't see it for AirPrint, your laptop's print dialog says "No printers found," or the initial WiFi setup on the printer just times out repeatedly. The Eero Pro 7 is a great mesh router, but a few of its defaults trip up older printers in ways that aren't obvious until you know where to look.
Two-part move that catches most cases at once: confirm WPA3 is off in eero Labs, then bring the printer within six feet of the gateway eero for the initial pairing. Open the Eero app, tap Discover, eero Labs, and confirm WPA3 shows as Off (it's opt-in, not default, but if you turned it on you may have forgotten). Move the printer into the same room as the gateway, run its WiFi setup, then put it back where it lives.
If that doesn't get it, here's the rest of the playbook.
Why Your Printer Won't Connect to the Eero Pro 7
The Eero Pro 7 is BE10800 tri-band Wi-Fi 7 with WPA3 opt-in via eero Labs. Common reasons printers fail:
- WPA3 is enabled: opt-in but if you turned it on, most pre-2022 printers can't connect.
- Printer needs 2.4 GHz only: the eero broadcasts a single SSID and steers your phone to 5 GHz; the printer can't see what your phone sees.
- mDNS/Bonjour discovery failing across mesh: AirPrint relies on mDNS and the eero sometimes doesn't propagate it cleanly between satellites.
- Printer paired but phone is on guest network: the two networks are isolated and printer discovery doesn't cross.
- WiFi password contains special characters: older printer keypads can't input apostrophes or symbols.
- Printer firmware out of date: older firmware doesn't support modern WiFi authentication.
- Static DHCP reservation gone after eero re-setup: after a factory reset, the printer's previous IP reservation is gone.
Confirm WPA3 Is Off in eero Labs
WPA3 on Eero Pro 7 is opt-in via eero Labs, not default; if you turned it on at some point, that's likely the printer's problem. Discover, eero Labs, toggle WPA3 off. Re-pair the printer, then optionally re-enable WPA3 once paired (most modern clients negotiate fine, most printers won't).
Move the Printer Within Six Feet of the Gateway
Initial WiFi pairing on a printer is much more sensitive to signal strength than ongoing operation. If you set the printer up across the house from the gateway, the handshake may fail repeatedly. Bring the printer into the same room as the gateway eero for the initial pairing.
Once it's connected, you can move it back to its final spot.
Use Your Phone on 2.4 GHz Temporarily
Many printers only support 2.4 GHz. The Eero Pro 7's single SSID steers your phone to 5 GHz, which means your phone can't even see what the printer is trying to connect to. Some printer setup apps require your phone to be on the same network as the printer is trying to join.
The eero doesn't let you split bands easily. The workaround is to use the printer manufacturer's app (HP Smart, Canon PRINT, Epson iPrint, etc.), which handles the band-switching logic. Make sure you're using the official manufacturer app, not a third-party utility.
Update the Printer's Firmware
Many older printers shipped with WiFi firmware that predates modern routers. Check the printer manufacturer's website (HP, Canon, Epson, Brother all have firmware downloads) and update via USB cable to a computer if WiFi pairing isn't working. After firmware update, retry the WiFi setup.
This often fixes printers that worked fine on an older router but can't pair with the eero.
Restart Discovery on Your Phone or Mac
If the printer is on the network but doesn't show up for AirPrint, the issue is mDNS discovery, not the printer itself. On iPhone or Mac, toggle WiFi off and back on. On Mac, you can also remove and re-add the printer in System Settings, Printers & Scanners.
This forces the device to re-broadcast for available printers via mDNS.
Power-Cycle the Gateway Eero
If mDNS propagation across the mesh is broken, restarting the gateway resets it. Unplug the gateway eero, wait 60 seconds, plug back in. Don't restart the satellites. Wait 5 minutes for the mesh to re-stabilize, then retry printer discovery.
Check Guest Network Isolation
If you're using a guest network, devices on it are isolated from the main network. The printer must be on the main network and your phone or computer must be on the main network too. Open Eero app, check which network each device is on, and move them to the same network.
Set a Static DHCP Reservation for the Printer
Once the printer is paired and online, give it a static IP. Open Eero app, tap Settings, Network Settings, Reservations & Port Forwarding, and add a reservation for the printer's MAC address. This means the printer always gets the same IP, even after the eero reboots, and AirPrint discovery is more reliable.
Reset the Printer's Network Settings and Pair Fresh
If the printer's WiFi memory is corrupted from previous failed attempts, reset only its network settings (not the whole printer); the menu path varies by manufacturer but is usually called "Restore Network Defaults" or "Reset LAN Settings." Then run the printer's WiFi setup wizard from scratch with the printer near the gateway eero.
