Modern office equipment is increasingly ditching cumbersome wires in favor of wireless technologies, and one of the most convenient features is Wi-Fi Direct. This protocol allows smartphones, tablets, and laptops to connect directly to a printer without a router, creating a one-to-one local network. However, when connecting for the first time, users are often required to enter a secret security key, which is hidden or randomly generated by default.
Finding this code can be a real quest if you don't know where the manufacturer has placed this information. Unlike a home router, where the information is often written on the bottom of the device, the location of this information on multifunctional devices (MFPs) varies depending on the brand and model. In this article, we'll explore all possible ways to access it, from simple stickers to resetting the settings via the menu.
Search for factory stickers and documentation
The fastest and most reliable way to find PIN code A physical inspection of the device is required to obtain a password or password. Manufacturers often place factory data on special labels attached to the device's casing. Look at the back, side, or bottom of the printer. Information may also be hidden under the removable paper tray or inside the cartridge compartment.
If there are no clear markings on the case, it's worth consulting the user manual or the device box. Newer models often come with a separate sheet labeled "Wi-Fi Direct Password" or "Wireless Direct Info." This sheet contains a unique SSID network and its corresponding password. Do not discard this paper immediately after unpacking, as you will need it again when resetting the network settings.
- 🔍 Look for a sticker that says "Wi-Fi Direct Info" on the back of the case.
- 📄 Check the inside of the scanner lid or paper feed tray.
- 📦 Keep the separate insert from the box with factory passwords.
It's worth noting that on some models, the password may be a default one, such as "12345678" or "00000000" if the device hasn't been configured previously. However, relying on default combinations isn't recommended, as modern security protocols require individual key generation for each device.
Printing a network configuration report
If a visual inspection yields no results, the most effective method is to print a service report. Almost all modern MFPs HP, Canon or Brother have the ability to print a wireless network configuration page. This document contains complete technical information, including the MAC address, IP address, and the Wi-Fi Direct password.
To initiate printing, you usually need to press a specific combination of buttons on the control panel. This is often the wireless network button or the "Information" (i) button. In some cases, you need to hold down two buttons simultaneously for a few seconds. Once the command is activated, the printer will print one or more pages of text and graphics.
⚠️ Caution: Make sure there is paper in the tray before initiating report printing to avoid paper feeding error and paper jam.
In the printed report, look for the "Wi-Fi Direct" or "Wireless Direct" section. It will list the network name (SSID) and the "Password" or "Passphrase" string. This is the character set you need to enter on the connecting device. If the password is displayed as an empty string or "Off," then Wireless Direct is currently disabled in the device settings.

Using the built-in menu display
Devices with a color touchscreen or advanced keypad allow you to display the password directly on the screen. This eliminates the need for paper and ink. Menu interfaces may vary, but the navigation logic is similar across brands. You'll need to find the section responsible for wireless connections.
Usually the path looks like this: you need to go to Settings (gear icon), then select Net or Wireless communicationInside this menu, look for the item Wi-Fi DirectWhen accessing it, you may be asked to enable the feature if it's disabled. Once enabled, the network name and password are often displayed on the screen, or a "Show Password" button appears.
On models Epson With E-ink or LCD screens the sequence may be as follows: Wi-Fi Direct → Setting up → Easy setupOn devices HP with screens Touchscreen Often, just tap the Wi-Fi Direct icon at the top of the screen to see a pop-up window with connection details.
| Brand | Path to the menu | Peculiarity |
|---|---|---|
| HP | Wireless → Wi-Fi Direct → Settings | The password is visible immediately after switching on. |
| Canon | Direct Lamp → Info Button | Often requires printing of a report |
| Epson | Wi-Fi Direct → Easy Setup | You can change the password manually. |
| Brother | Settings → Network → Wi-Fi Direct | PIN login required |
Reset network settings to factory defaults
In situations where the previous owner changed the password and you don't know the new one, or if the device was purchased second-hand without documentation, a full network reset may be necessary. This will restore all wireless settings to factory defaults, including the password, which will be found on the manufacturer's sticker or in the documentation.
It's important to understand that resetting the network doesn't affect printer settings, such as print quality or region, but it will delete all saved Wi-Fi profiles. To perform this procedure on most models, press and hold the wireless button and the cancel button (often marked with a red cross or phone icon) simultaneously for 10-15 seconds. The network indicators will begin flashing, indicating the reset process.
What happens when you reset your network?
When you reset your network settings, the printer forgets the name and password for your home router. You'll have to reconnect it to the internet using the standard WPS procedure or the setup menu, but the Wi-Fi Direct password will return to the factory default.
After rebooting the communication module, the device will create a new access point with a factory name. At this point, the password will match the one printed on the housing label. This is the only guaranteed way to gain access if standard methods fail and the device is locked with an unknown code.
Setting up via the manufacturer's application
Modern ecosystems allow you to control your printer via your smartphone, which opens up additional opportunities for accessing information. Apps like HP Smart, Canon PRINT Inkjet/SELPHY or Epson iPrint can display connection status and security settings.
If your phone is already connected to the printer's Wi-Fi network (even if the internet is down), launch the app. You can sometimes find a "Wi-Fi Direct" tab under "Printer Settings" or "Device Information." However, for security reasons, many apps only show the status ("On/Off"), hiding the actual password. However, you can initiate a network reconfiguration process through the app, which will help restore access.
Sometimes the app may prompt you to change your password to something more convenient. This is a great opportunity to replace a complex set of random characters with an easy-to-remember combination. The changes will take effect immediately after confirmation, and old devices will need to be reconnected with the new key.
Common connection problems
Even with the correct password, users may encounter connection errors. Often, the problem lies not in the code itself, but in the frequency range or operating system limitations. Wi-Fi Direct operates on the 2.4 GHz frequency, and if your mobile device is configured to prioritize 5 GHz, conflicts may occur.
Another common mistake is attempting to connect more than two devices simultaneously. The Wi-Fi Direct protocol has a limit on the number of clients. If a laptop is already connected to the printer, the phone may not allow it to connect to the network, requiring one of the devices to be disconnected. It's also worth checking that "Mobile Data" mode isn't enabled on the phone, as this can sometimes prevent the printer from properly connecting to the local network.
⚠️ Important: When entering your password, pay attention to the case of letters and similar characters (the number 0 and the letter O, the number 1 and the letter l). A single character error will prevent you from connecting.
If the printer's lights continue to flash blue or orange after entering the password, try forgetting the network on your phone and deleting the device profile in the system. Then reboot both devices and repeat the entry process. In 90% of cases, this resolves the frozen connection issue.
Wireless connection security
Using Wi-Fi Direct is convenient, but it requires understanding the security risks. Since the connection is direct, bypassing the router's firewall, an attacker within range could theoretically attempt to brute-force the password. Therefore, never leave Wi-Fi Direct enabled unless absolutely necessary.
It's recommended to activate direct communication mode only during printing or scanning, and then disable it via the menu or app. This minimizes the window of opportunity for unauthorized access. Additionally, regularly changing the password (if the model allows it) or periodically resetting the network settings will help maintain a high level of security.
Remember that WPA2 encryption, used by Wi-Fi Direct, is quite secure, but only if you use a complex password. Changing the password to "12345678" for convenience will significantly reduce your device's security. In a corporate environment, the use of open Wi-Fi Direct networks should be strictly regulated.
Frequently Asked Questions (FAQ)
Where can I find the password if the sticker on the printer has worn off?
If the sticker is illegible, the only option is to print a network configuration report from the control panel or completely reset the network settings to factory defaults so that the password becomes the default (specified in the instructions).
Is it possible to connect to Wi-Fi Direct without a password?
No, the WPA2 security protocol requires mandatory authentication. A password-less connection is impossible unless the feature has been specifically configured for open network mode (which is extremely rare on modern models).
Why does the phone see the printer's network, but says "No Internet access"?
This is normal behavior. Wi-Fi Direct creates a local network only for printing data; it does not provide internet access. Don't disable your mobile data if you need it for other applications.
How many devices can be connected via Wi-Fi Direct at the same time?
Printers typically support up to five simultaneous connections. However, only one device can be actively printing at a time; the others will be queued.
