USB works but Wi‑Fi fails — HP, Epson, Canon, Brother on Windows 10/Windows 11 or Mac

Technician avatar Technician
Hey! We’ll get wireless printing working. Tell me the brand (HP, Epson, Canon, Brother) and device (Windows 10/11, macOS, iOS/AirPrint, Android). Since USB printing works but Wi‑Fi does not, we’ll check the 2.4 GHz SSID, DHCP lease, static IP / DHCP reservation, AP/Client isolation, and mDNS/Bonjour for AirPrint.
Customer
Windows 11 laptop + iPhones. Printer: HP OfficeJet Pro. Over USB it prints fine. Over Wi‑Fi it’s offline or disappears after a router reboot. We use a dual‑band router with one SSID.
Technician avatar Technician
Got it. Common causes when a printer connects via USB but not Wi‑Fi:
• The printer is on a different band or SSID (5 GHz only / band‑steering) — many models need 2.4 GHz.
• DHCP gives a new IP on every restart; Windows/macOS cache the old IP → printer shows offline.
• Router features like AP/client isolation, guest network, or firewall rules block LAN‑to‑LAN traffic.
• mDNS/Bonjour (for AirPrint) is filtered; iPhone/iPad can’t discover the printer.
• Queue added as USB only or WSD/IPP class driver that doesn’t track IP changes.
Plan: rejoin 2.4 GHz, assign a static IP (DHCP reservation), re‑add driver/queue, then verify Bonjour and firewall.
Customer
How do I put the printer on 2.4 GHz and give it a static IP?
Technician avatar Technician
Connect to 2.4 GHz & set DHCP reservation:
1) On the printer panel: Wireless/Network → Setup → Wi‑Fi → choose the 2.4 GHz SSID (create separate SSIDs if your router hides bands).
2) In the router app/web UI: find the printer in the device list → DHCP Reservation / Address Reservation → bind its MAC to a fixed IP (e.g., 192.168.1.50). This is safer than manual static IP.
3) Reboot router and printer. Now the IP address won’t change after restart, fixing “printer offline” on Wi‑Fi.
Customer
Windows still says Offline. Should I remove and re‑add the printer?
Technician avatar Technician
Yes. Repair the wireless queue on Windows 10/11:
• Settings → Bluetooth & devices → Printers & scanners → remove old entries (USB/WSD/IPP Class).
• Click Add device → Add manually → pick TCP/IP and enter the reserved IP → select the vendor driver (HP Full Feature/UPD, Epson, Canon UFRII, Brother).
• In Printer properties → Ports ensure it uses the Standard TCP/IP Port for that IP. This prevents Windows from switching to USB‑only mode.
Customer
What about our iPhones? AirPrint can’t find the printer unless we plug in USB.
Technician avatar Technician
AirPrint discovery relies on Bonjour/mDNS (UDP 5353). Make sure:
• Phone and printer are on the same subnet and not on a Guest SSID.
• Router options like Client/AP isolation are disabled for the main SSID.
• If you run security software or Pi‑hole, allow mDNS and IPP/631, RAW/9100 as needed.
• On the printer, enable AirPrint / Bonjour service. Then re‑add the printer on iOS.
Customer
We have one SSID for 2.4/5 GHz (band steering). Could that break Wi‑Fi printing?
Technician avatar Technician
Sometimes. Many printers only join 2.4 GHz, while phones jump to 5 GHz and can’t discover them. Options:
• Create a dedicated 2.4 GHz SSID for the printer and IoT devices.
• Keep both bands on the same LAN (no isolation) and disable “Smart Connect” if it forces 5 GHz.
• On mesh systems, confirm mDNS across nodes is supported so AirPrint works room‑to‑room.
Customer
Could our firewall or VPN block the printer when on Wi‑Fi?
Technician avatar Technician
Yes. On PCs, set the network to Private and allow File and Printer Sharing. In security suites, allow mDNS (5353), IPP/631, RAW/9100, and WSD if used. Corporate or app‑level VPNs often block local LAN — pause VPN when printing or enable “Allow access to local network”.
Customer
We also see “Wi‑Fi Direct” on the printer. Should we use that?
Technician avatar Technician
Wi‑Fi Direct is a temporary peer‑to‑peer mode. It’s fine for quick prints but won’t keep the printer on your home Wi‑Fi network or be discoverable by all devices. Prefer joining the main SSID with a DHCP reservation/static IP.
Customer
Any brand‑specific steps for HP, Epson and Brother?
Technician avatar Technician
HP: Use HP Smart to reconnect Wi‑Fi, then in router set DHCP reservation. Add on Windows as TCP/IP with HP driver; on Mac, choose AirPrint or HP driver.
Epson: Run Epson Setup/NetConfig to join 2.4 GHz; ensure Bonjour is enabled. Add via IP on Windows if WSD fails.
Canon: Use Wireless LAN Setup, then driver UFR II/Generic Plus with TCP/IP port.
Brother: Use Wireless Setup Wizard or iPrint&Scan; confirm AP Isolation disabled on router; add via Standard TCP/IP port.
Customer
Great — after setting the DHCP reservation and re‑adding the TCP/IP port, Wi‑Fi printing works on PCs and phones.
Technician avatar Technician
Summary: When a printer works over USB but not Wi‑Fi, stabilize the network path: join 2.4 GHz, set a DHCP reservation/static IP, re‑add the queue via TCP/IP, and allow mDNS/Bonjour through firewalls. Disable AP/Client isolation and avoid Guest SSIDs. Need hands‑on help? Open the chat.

Quick answer: the accepted fix

Accepted fix when USB printing works but Wi‑Fi printing does not (Windows 10/Windows 11/Mac/iOS): connect the printer to 2.4 GHz, create a DHCP reservation (static IP), re‑add the printer via TCP/IP with the vendor driver, and ensure mDNS/Bonjour and IPP/RAW are allowed in router/firewall. Avoid Guest/AP isolation.


Printer goes offline after router restart — keep the same IP

If the printer drops off Wi‑Fi or shows offline after reboot, DHCP likely assigns a new address. Make a DHCP reservation for the printer’s MAC in the router so its IP address never changes. Then re‑add the queue using a Standard TCP/IP port on Windows or AirPrint/IP on macOS.

How to verify wireless printing works

Print a status/test page from the printer to confirm the Wi‑Fi IP. From a PC, open a browser to that IP — the web admin should load. If it doesn’t, check AP isolation, guest SSID, and firewall. From iPhone/iPad, try AirPrint again; if missing, verify Bonjour/mDNS is not blocked.

Wireless printing — troubleshooting tips

Most Wi‑Fi issues come from band/SSID mismatch, changing IPs, or blocked discovery.

Quick path: join 2.4 GHz SSID → set DHCP reservation/static IP → re‑add queue via TCP/IP → enable Bonjour/mDNS → disable AP/Client isolation and avoid Guest networks → allow IPP/RAW through firewall/VPN. For HP/Epson/Canon/Brother, vendor setup tools simplify Wi‑Fi reconnect.

FAQ

Why does my printer work via USB but not over Wi‑Fi?

Usually band/SSID mismatch (printer on 2.4 GHz, phone on 5 GHz), changing IPs without a reservation, or blocked discovery (mDNS/Bonjour). Join the same 2.4 GHz SSID, set a DHCP reservation/static IP, re‑add the queue via TCP/IP, and allow IPP/RAW through firewall.

How do I stop the printer from going offline after a router restart?

Create a DHCP reservation so the printer keeps the same IP. Then add it on Windows using a Standard TCP/IP port or on macOS as AirPrint/IP. This prevents “offline” caused by IP changes.

AirPrint can’t find my printer — what now?

Ensure iPhone/iPad and printer are on the same SSID; disable Guest or AP isolation; allow mDNS/5353 in router/security apps; enable Bonjour/AirPrint on the printer.

Will Wi‑Fi Direct fix this?

Wi‑Fi Direct is temporary and device‑to‑device. For whole‑home printing, join the printer to your main 2.4 GHz SSID with a DHCP reservation.

Brand tips for HP / Epson / Canon / Brother?

Use each vendor’s setup tool to re‑join Wi‑Fi, then lock a DHCP reservation. Add the printer via TCP/IP (Windows) or AirPrint/IP (Mac). Ensure drivers are the full vendor versions, not a class/IPP placeholder.

Common wireless problems and quick fixes
SymptomLikely causeQuick fix
USB works, Wi‑Fi “Offline” New DHCP IP; cached port DHCP reservation; re‑add as TCP/IP port
Phone can’t find printer 5 GHz vs 2.4 GHz; mDNS blocked Use 2.4 GHz SSID; enable Bonjour; allow UDP 5353
Works on PC, not on Mac/iOS AirPrint disabled or filtered Enable AirPrint; disable AP/Client isolation; same subnet
Fails on Guest or VPN LAN access blocked Use main SSID; allow local network in VPN; firewall rules for IPP/RAW

Step‑by‑step (Windows 10/11)

  1. Connect printer to 2.4 GHz SSID; create a DHCP reservation in the router.
  2. Remove old queues; Add printer → Add manually → TCP/IP; install the vendor driver.
  3. Open Printer properties → Ports and confirm the Standard TCP/IP port points to the reserved IP.
  4. Set network to Private; allow File and Printer Sharing and mDNS/IPP/RAW through firewall.

Step‑by‑step (macOS)

  1. Join the printer to the same 2.4 GHz SSID; reserve its IP in the router.
  2. In System Settings → Printers & Scanners, add the printer with AirPrint or via IP (IPP/HP Jetdirect).
  3. Ensure Bonjour is enabled; avoid Guest SSID and AP isolation.
