Modern printing technologies have advanced significantly, making cumbersome cables connecting a device to a computer a thing of the past. Wireless printing opens up new possibilities for users, allowing them to send documents and photos directly from a smartphone or tablet, from anywhere in the home. However, the initial setup process often presents difficulties for inexperienced users, especially when it comes to entering passwords on the tiny screens of MFPs.
Fortunately, there is technology designed to simplify this process as much as possible and eliminate the need to manually enter complex combinations of security symbols. This standard Wi-Fi Protected Setup, which allows you to establish a connection in just two clicks. This method is ideal for those who don't want to understand the intricacies of network settings, IP addressing, or drivers, but want to get results right away.
In this article, we'll cover in detail how to activate this feature on your device, the nuances that exist for different manufacturers, and what to do if automatic pairing doesn't work the first time. You'll learn how to use it safely. WPS and what precautions should be taken to protect your home network from unauthorized access.
What is WPS technology and how does it work?
Abbreviation WPS Wi-Fi Protected Setup stands for Wi-Fi Protected Setup. It's a wireless security standard developed by the Wi-Fi Alliance to simplify the process of connecting devices to a home network. The basic idea behind the technology is to create a secure communication channel between the router and the client device (in this case, the printer) without the need to manually enter a lengthy Wi-Fi password.
The operating principle is based on the automatic exchange of encryption keys. When you activate search mode on the printer and press the corresponding button on the router, the devices exchange special data packets. The router transmits the network name (SSID) and the encryption key, after which the connection is established automatically.
There are two main methods for implementing this protocol. The first is using a physical button, which will be discussed below. The second method is entering a special PIN code, which is generated by the device and entered into the router's web interface. For printers, the push-button option is most often used, as it's the most convenient and fastest.
β οΈ Warning: WPS technology has known vulnerabilities in the PIN code method, so after completing the printer setup, it is strongly recommended to disable the WPS function in the router settings if you do not plan to connect new devices in the near future.
Checking hardware compatibility before starting
Before you take any action, you need to make sure your equipment supports this standard. Not all printer models, even modern ones, are equipped with a module. Wi-Fi and a quick setup function. This information is usually included in the model name or on the box.
Look at the front panel of your printer. Look for a wireless network icon or a separate button labeled Wireless or WPS This is the first sign of technology support. If the printer is older and doesn't have a display, the likelihood of built-in Wi-Fi is reduced, but it's still worth checking.
The state of your router is also important. Most modern routers from providers and vendors like TP-Link, ASUS, and Keenetic support this standard by default. However, in some corporate or older models, this feature may be software-disabled by the network administrator.
Below is a table to help you determine the presence of support on devices of popular brands based on external signs:
| Device brand | Availability of a WPS button | Status indicator | Additional requirements |
|---|---|---|---|
| HP LaserJet/Deskjet | Often a separate button | Flashing blue icon | Wi-Fi Direct mode must be turned off. |
| Canon PIXMA | Button combination | Orange indicator | You need to hold the button for 3 seconds |
| Epson EcoTank | Separate button | Green/Orange | Drivers must be installed on the PC |
| Brother HL/MFC | In the menu or button | Blue flashing | Distance to the router up to 3 meters |
Step-by-step instructions: connecting using the button on the router
The most common and convenient method is to use the physical button on the router. This method doesn't require entering any codes and works on a "press and forget" basis. First, you need to prepare the printer itself to search for the network.
Turn on the printer and wait until the boot process is complete and the device stops making operating sounds. Make sure there is paper in the tray and the cartridges are installed correctly, as some models do not activate the network if there are consumable errors. Locate the button with the symbol on the control panel. Wi-Fi or an inscription Network.
Press and hold this button for 2-3 seconds until the wireless indicator starts flashing. This indicates that the module is waiting for a pairing command. You now have approximately 2 minutes to activate the router's response.
βοΈ Ready to connect
Go to your router. Find the button marked on its body. WPSIt may be separate or combined with the Wi-Fi power button (sometimes marked with a lock icon or two arrows). Press it briefly (for 1-2 seconds). The WPS indicator on the router should light up or flash.
After this, return to the printer and observe the indicator light. If everything went well, the blinking will stop and the indicator light will turn solid (usually blue or green). This means that IP address received and connection with the router established.
Alternative method: button on the printer itself
Some modern printer models, especially those equipped with touchscreens or simplified control panels, allow you to initiate the connection process directly from the printer itself, without having to go to the router. This is only possible if the router also has a physical button or one is enabled virtually in the settings.
Unlike the previous method, this one reverses the process. You don't need to put the printer into standby mode first. The whole process happens in reverse. First, you activate discovery mode on the router.
Click the button WPS on the router and hold it for a few seconds until the corresponding indicator flashes. The router will now wait for a new device to connect for 120 seconds. You must press the button on the printer during this time.
Find the wireless button on the printer's control panel. Often, to activate the WPS function, you need to press it simultaneously with another button, such as Wireless network + Information or hold for 5 seconds. It's best to check the exact combination in the instructions for your specific model. HP, Canon or Epson.
β οΈ Note: Router and printer interfaces are constantly being updated. If the described method doesn't work, check the manufacturer's official documentation, as new firmware versions may change the sequence of actions or button layout.
Setup via software and PIN code
If the physical buttons are missing, damaged, or unresponsive, you can use the software method. This requires the computer used for setup to be connected to the same Wi-Fi network you plan to connect the printer to, or connected to the router via cable.
To get started, run the installation disk or download the full driver package from the manufacturer's official website. During installation, select "Wireless" or "Wi-Fi" as the connection type. The program will automatically detect available networks and suggest connection methods.
When the installer suggests a method WPS, select the "PIN" option. An eight-digit code will appear on your computer screen. This code will need to be entered into the router interface or, in rare cases, on the printer's control panel if it has a keyboard.
What should I do if the program doesn't see the printer?
If the installer fails to detect the device, try temporarily disabling your antivirus and Windows Firewall. Also, make sure the computer and printer have the same date and time, as out-of-sync clocks can block WPS security certificates.
Enter the received PIN code in the appropriate field in the router's security settings (Wireless -> WPS section). After confirmation, the router will transmit network data to the printer. This method is less convenient than the push-button method, but it is a reliable alternative if you have problems with the hardware buttons.
Solution and possible errors
Even if you follow all the instructions, you may still encounter issues with the connection failing. The printer's indicator light continues to flash or turns orange, indicating an error. One common cause is excessive distance between the devices during setup.
Make sure the printer and router are in the same room and no more than 1-2 meters apart when pairing. After successfully establishing a connection, you can move the printer to another location with a stable signal. Also, check if filtering is enabled on the router. MAC addresses.
Another common issue is a timeout. The connection window is only 2 minutes. If you miss the second button, you'll need to start the process over again. Wait until the lights stop flashing and then repeat the process.
If all else fails, try resetting the printer's network settings to factory defaults. This is usually done with a key combination (e.g., "Wireless" + "Cancel"). After the reset, repeat the connection procedure.
Safety issues and final recommendations
Use of technology WPS This makes life much easier, but it's important to remember security. As mentioned earlier, the PIN code method is vulnerable to brute-force attacks. Therefore, after you've successfully connected all your devices, it makes sense to go to your router settings and disable the WPS function completely.
This won't disconnect the printer from the network, but it will prevent unauthorized connections from new devices by attackers within your Wi-Fi range. The printer will continue to operate reliably using the stored encryption keys.
To summarize, connecting via WPS is the fastest way to set up wireless printing. The key is to act quickly and carefully monitor the device indicators. If you've followed all the steps correctly, your printer will be available for printing from all devices in the house.
Is it possible to connect a printer via WPS if there is no button on the router?
Yes, you can. In this case, you'll need to log into the router's web interface via a browser (usually at 192.168.0.1 or 192.168.1.1), find the Wireless or Wi-Fi section, then the WPS tab, and press the "Start WPS" or "Add Device" virtual button. Then, follow the printer's instructions.
Why is the Wi-Fi light on my printer blinking blue but not staying on?
A blinking blue light typically means the printer is in setup mode or is attempting to connect to the network but hasn't yet received an IP address. If the blinking continues for a long time, the connection hasn't been established. A steady blue light indicates a successful connection to the Wi-Fi network.
Does WPS work on 5GHz?
Technically, the WPS standard supports both frequencies, but most older and budget printers only operate in the 2.4 GHz band. If your router is broadcasting two networks with the same name, try temporarily separating them or forcing the router to switch to 2.4 GHz mode for configuration.
What should I do if the router requires a PIN code and I donβt know it?
The WPS PIN is usually located on a sticker on the bottom or back of the router (often labeled as WPS PIN). If there is no sticker, the code can be found in the router's web interface under wireless security settings. However, knowing the code is not required to connect a printer using the push-button.
