What Does WLAN Mean on a Printer? The Light, the Button and How to Fix It
Last Updated:Quick answer: WLAN stands for wireless local area network, which is simply your Wi-Fi network. On a printer, the WLAN light, button or menu controls and reports its Wi-Fi connection. A solid WLAN light means the printer is connected, a blinking light means it is searching, waiting for WPS or has lost the network, and an unlit light usually means wireless is turned off. "WLAN" and "Wi-Fi" mean the same thing here.

Key Takeaways
- WLAN = wireless local area network. It's the technical name for the Wi-Fi network in your home or office.
- A WLAN light shows connection status; a WLAN button starts wireless setup or WPS; a WLAN menu turns Wi-Fi on or off.
- Solid = connected. Blinking = connecting or lost. Off = wireless disabled.
- Canon labels its wireless toggle "WLAN active/inactive"; Brother uses "WLAN(Wi-Fi)" and an "Enable WLAN?" prompt.
- WLAN is different from Wi-Fi Direct (Canon calls it Wireless Direct), which connects a phone straight to the printer without a router.
What Does WLAN Stand For on a Printer?
WLAN stands for wireless local area network. It's the network your router creates, the same thing most people just call Wi-Fi. When a printer says WLAN, it is talking about its connection to that network.
Manufacturers use "WLAN" in menus because it's the formal networking term, alongside "LAN" (local area network) for a wired Ethernet connection. So a printer menu that offers Wired LAN and Wireless LAN (WLAN) is asking whether you want to connect with a cable or over Wi-Fi.
| Term on the printer | Plain English | Needs a router? |
|---|---|---|
| WLAN / Wireless LAN | Connect to your Wi-Fi network | Yes |
| LAN / Wired LAN | Connect with an Ethernet cable | Yes |
| Wi-Fi Direct / Wireless Direct | Phone or laptop connects straight to the printer | No |
| WPS | One-button pairing with your router | Yes (router must support WPS) |
| SSID | The name of your Wi-Fi network | — |
What Does the WLAN Light on My Printer Mean?
A solid WLAN light means the printer is connected to your wireless network. A blinking light means it is trying to connect, is in setup or WPS mode, or has lost its connection. No light means wireless is switched off. This matches how Brother describes its Wi-Fi light (on = connected; blinking = connection down or connecting) and how HP describes a blinking blue Wireless light (setup mode).
Is a Blinking WLAN Light Bad?
Only if it never stops. Blinking is normal for a minute or two during setup or after the router restarts. If it blinks for more than a few minutes, the printer can't find or join the network. Work through the fixes below.
How Do I Fix a Blinking WLAN Light?
Restart the router and printer, confirm the printer is on a 2.4 GHz-compatible network, then re-run the printer's wireless setup or WPS. Most blinking WLAN lights clear after one of these steps.
- Power-cycle both devices. Unplug the router for 30 seconds, let it fully restart, then turn the printer off and on.
- Check the band. Many home printers only connect on 2.4 GHz. If your router merges 2.4 and 5 GHz under one name, temporarily enable a separate 2.4 GHz network for setup.
- Re-run wireless setup from the printer panel or app (HP Smart, Canon PRINT, Epson Smart Panel, Brother Mobile Connect). Use the brand steps below.
- Try WPS. Start WPS on the printer, then press the WPS button on your router within about two minutes. Our guide to the WPS PIN on a printer covers PIN-based WPS too.
- Move closer. Thick walls and distance weaken the signal. Test the printer within 10–15 feet of the router.
- Check the password. Wi-Fi passwords are case-sensitive, and a recently changed password disconnects every printer.
- Print a network configuration page to see the signal strength, the network the printer thinks it's on, and its IP address. See how to find your printer's IP address.
How Do I Turn On WLAN on My Printer?
Open the printer's network or LAN settings and switch wireless (WLAN) on, then run the wireless setup wizard. The exact menu names vary by brand:
Canon
On Canon touchscreen models like the PIXMA TS9000 series, go to LAN settings > Wireless LAN > WLAN active/inactive. The same menu offers Wireless LAN setup (Easy wireless connect, manual connect or WPS push button) and WLAN setting list, which can print your current settings. Models without a screen use a Wi-Fi button; a solid blue Wi-Fi lamp generally means wireless is on and connected.
Brother
On Brother models like the HL-L3220CW, press Network > WLAN(Wi-Fi) > WPS/Push Button; on models with an All Settings menu, the path is Settings > All Settings > Network > WLAN(Wi-Fi). When asked "Enable WLAN?" choose On or Yes, and the wireless setup wizard starts. More steps: how to connect a Brother printer to Wi-Fi.
HP
HP usually labels it Wireless rather than WLAN. Press the Wireless button (or open Wireless settings on the touchscreen) and finish setup in HP Smart. A blinking blue Wireless light with cycling signal bars means the printer is in setup mode. Stuck? Try our 11 HP Wi-Fi fixes.
Epson
Epson also says Wi-Fi. On button-only EcoTank models, flashing Wi-Fi lights indicate a connection error; Epson's instructions say to press the Wi-Fi button to clear it and try again. On models with a screen, use Settings > Network Settings > Wi-Fi Setup, or set up from the Epson Smart Panel app.

What's the Difference Between WLAN and Wi-Fi Direct?
WLAN connects the printer to your router so every device on the network can print. Wi-Fi Direct (Canon's "Wireless Direct") creates a small private network from the printer itself, so a phone or laptop can connect directly with no router. Use WLAN for everyday home and office printing; use Wi-Fi Direct when there's no router, or for a guest who shouldn't join your network.
| WLAN (Wi-Fi network) | Wi-Fi Direct / Wireless Direct | |
|---|---|---|
| Router required | Yes | No |
| Who can print | Any device on your network | Devices connected directly to the printer |
| Internet on the phone while printing | Yes | Often not, while connected to the printer |
| Best for | Everyday printing, multiple users | No router, guests, quick one-off prints |
Should I Turn WLAN Off on My Printer?
Turn WLAN off only if you connect by USB or Ethernet and never print wirelessly. It slightly reduces network clutter and removes one more connected device. If you print from phones or several computers, leave it on. Keeping the printer's firmware current is still smart for security, but if you use compatible ink, read how firmware updates can block third-party ink before updating an HP.
Why Does My Printer Say WLAN Connected but Won't Print?
The printer is on the network, but your computer or phone can't reach it. That's usually a stale printer queue, a changed IP address, or a phone on a different network or band. Restart the computer, remove and re-add the printer, and confirm both devices are on the same Wi-Fi. If the queue shows "offline," use our printer offline fixes; for phones, see why won't my printer connect to my phone.
Frequently Asked Questions
Is WLAN the same as Wi-Fi?
For printers, yes. WLAN is the general term for a wireless local area network, and Wi-Fi is the brand name of the standard almost every WLAN uses. A printer's WLAN setting is its Wi-Fi setting.
What does the WLAN button on a printer do?
Depending on the model, pressing it turns wireless on or off, starts wireless setup, or starts WPS pairing. Holding it down often starts WPS or prints a network report; check your manual for the exact hold time.
What does WLAN mean on a Brother printer?
It's Brother's name for its Wi-Fi settings. The menu reads WLAN(Wi-Fi), and turning on WLAN starts the wireless setup wizard.
What does WLAN mean on a Canon printer?
It's the wireless network connection. Canon's LAN settings include "WLAN active/inactive" to switch wireless on or off and a "WLAN setting list" to view or print your network details.
Why is my WLAN light off?
Wireless is probably disabled, often after a reset or after someone connected a USB or Ethernet cable. Turn WLAN on in the network menu or press the wireless button, then reconnect.
Does a printer need WLAN to work?
No. You can print over USB or Ethernet with WLAN off. WLAN is only needed to print wirelessly over your home or office network.
Can a printer connect to 5 GHz WLAN?
Some newer models can, but many home printers support only 2.4 GHz. Check the specifications; if yours is 2.4 GHz only, make sure your router broadcasts that band.
What is WLAN signal strength on a network report?
It's how strongly the printer receives your router. Weak signal causes dropouts and offline errors. Move the printer or router closer, or add a mesh node nearby.
Connected? Keep It Printing
Once your printer is back on Wi-Fi, keep spare ink or toner on hand so the next interruption isn't an empty cartridge.
