To complete a Canon MX340 wireless setup, you need an access point or wireless router, ad-hoc direct connections are not supported, and the printer must be powered on with the Wi‑Fi lamp lit blue.
Canon MX340 wireless setup requirements
Your wireless router or access point must already be configured and available. The Canon PIXMA MX340 does not support ad‑hoc (device‑to‑device) wireless connections; it requires a standard infrastructure network. Canon documents that an access point or wireless router is required; ad-hoc direct wireless connection is not supported. Before you begin, make sure the printer is plugged in and turned on. When wireless LAN is enabled, the printer’s Wi‑Fi lamp glows blue.
Enable wireless LAN on the Canon MX340
- Press Menu on the printer’s control panel.
- Select Device settings.
- Select LAN settings.
- Select WLAN active/inactive.
- Select Wireless LAN active, then press OK.
The printer's control panel navigation uses a Menu button, then Device settings, then LAN settings, then WLAN active/inactive, then Wireless LAN active, then OK. After this step, the Wi‑Fi lamp should turn blue, confirming that the printer’s wireless radio is on. The Wi‑Fi lamp should light blue when wireless LAN is enabled.
Connect the MX340 to Wi‑Fi using WPS push button
- On the printer, select Wireless LAN setup, then press OK.
- Select WPS, then press OK.
- Select Push button method, then press OK.
- Press and hold the WPS button on your wireless router or access point for about 5 seconds.
- Within 2 minutes, press OK on the printer.
The printer's control panel navigation for WPS uses Wireless LAN setup, then OK, then WPS, then OK, then Push button method, then OK. Press and hold the WPS button on the access point for about 5 seconds, then press OK on the printer within 2 minutes. The printer will now attempt to connect to your Wi‑Fi network. Once successful, the Wi‑Fi lamp remains solid blue.
Install Canon MX340 drivers on your computer
Visit the Canon support page for the PIXMA MX340 and download the driver that matches your operating system. The installation process varies slightly between Windows and macOS, but in both cases you will run the downloaded file and follow the on‑screen prompts. After the driver is installed, your computer should automatically detect the MX340 on the same network. This completes the wireless printer setup and mobile printing capability, allowing you to send jobs from any device connected to your home or office network.
Troubleshooting Canon MX340 wireless connection
- Router must be ready: The access point or wireless router must already be configured and broadcasting a network. If the router is not set up, the printer cannot join it. If wireless setup is used, the router or access point must already be configured and available.
- Check the blue Wi‑Fi lamp: If the lamp is off, wireless LAN is not active. Repeat the steps under “Enable wireless LAN on the Canon MX340” to turn it on.
- If you wait too long, the connection attempt will time out.
If the printer still does not appear on the network, verify that your router supports WPS and that no other device is currently using the WPS pairing process.
Frequently Asked Questions
Do I need an internet connection for wireless printing?
No. The Canon MX340 connects to your local Wi‑Fi network, so you can print from any device on that network without an internet connection. An internet connection is only required for cloud‑based features or firmware updates.
What should I do if the printer does not appear on the network after setup?
First, confirm that the printer’s Wi‑Fi lamp is lit blue. If it is, restart both the printer and your router. Then run the wireless setup again from the printer’s menu. If the problem persists, check that your router is not blocking the printer’s MAC address and that the network name (SSID) is not hidden.
Can I print from a mobile device without installing a Canon app?
However, once the printer is on your Wi‑Fi network, you may be able to print using your device’s built‑in printing features (such as AirPrint on iOS or the default print service on Android), provided the device and printer are on the same network.
Why doesn’t the printer find my Wi‑Fi network during setup?
Also ensure that the router’s WPS feature is enabled. If the network is hidden, you will need to enter the SSID manually, the WPS push‑button method only works with visible networks.
Do I need to install drivers on every computer that will print wirelessly?
Yes. Each computer that sends print jobs to the MX340 must have the correct Canon driver installed. After the printer is connected to your Wi‑Fi network, download and install the driver from the Canon support page on each computer.
