It's quite common to need to connect a new device to a wireless network but have forgotten the password. Many users mistakenly believe that HP LaserJet printer Stores this secret somewhere deep within its menu, accessible to everyone. However, the security architecture of these devices is structured differently: the printer often acts as a client receiving settings rather than a repository of access keys for the user.
However, there are proven ways to restore access or find out current connection settings. In most cases, this doesn't involve directly "reading" the password from the screen, as budget models often lack it, but rather using workarounds. We'll look at methods that will help you restore your connection without wasting time.
It is worth noting right away that modern models with color displays and an operating system HP FutureSmart may have more flexible display settings. However, for classic laser models, such as the series P1102, M102, M203The Pro M402 requires a different approach than working with touchscreen multifunctional devices. Understanding your device type is the first step to success.
Direct viewing on devices with a display
If your HP LaserJet Equipped with a full graphical display, the chances of finding saved data are significantly higher. In such models, the operating system allows you to display network status reports. You'll need to approach the device and use the navigation buttons to access the settings menu.
Usually the path looks like this: you need to select the wireless icon or go to the section Network (Network). Next you should look for a subsection Wireless Menu or Wi-Fi DirectThis is where information about the current connection is stored. On some models, the password may be displayed in plain text in the security field.
However, most often, for security reasons, password characters are hidden behind asterisks or dots. In this case, direct reading is impossible without special utilities. But you can see Network SSID (name) to which the printer is connected, which is already half the solution. If you know the network name, all that's left to do is remember the router password or look it up on another device.
⚠️ Attention: On non-touchscreen models, navigation is performed using the arrow keys. Do not attempt to press non-existent keys, as this may disrupt your current IP addressing settings.
For touchscreen devices, the interface can be more user-friendly. Sometimes, just tapping the wireless network icon on the home screen will display a pop-up window with connection details. If there's a "Show password" button or a similar eye, you're in luck—the details will be displayed.
Using WPS technology to connect without a password
The most effective way to connect a printer if you don't remember the password is to use technology WPS (Wi-Fi Protected Setup). This method allows devices to exchange encryption keys automatically by physically pressing a button on the router. You don't need to know the network access code itself.
To use this method, make sure your router supports WPS. There should be a corresponding button on the front or back of the router. On printers HP LaserJet This feature must also be activated. The synchronization process takes no more than two minutes and does not require any character input.
- 📡 Find the WPS button on your wireless router and press it (sometimes you need to hold it for 2-3 seconds until the indicator light flashes).
- 🖨️ On the printer control panel, press the Wireless button or go to the Network Settings menu.
- 🔄 Select "Wi-Fi Protected Setup" or "WPS" and confirm the action.
- ✅ Wait until the wireless indicator on the printer stops flashing and turns solid.
After a successful connection, the printer will automatically save the access key in its memory. Although you still won't see the password in plain text, the device will have full access to the network. This method is ideal when you need to print a document urgently and don't have time to remember complex character combinations.
Printing a network configuration report
One of the most reliable ways to obtain information about network settings is to print a special service document. HP LaserJet Can generate a "Configuration Report" or "Network Setup Page." This sheet of paper will contain detailed information about the current connection status.
To initiate printing, you typically need to press a specific button on the control panel. For models without a display, the wireless button or the "Cancel" button is often used, which must be held for 5-10 seconds. For models with a display, the command is located in the menu. Reports (Reports) -> Network Configuration (Network configuration).
In the printed document, pay attention to the section Wireless or 802.11 DetailsThe printer's IP address, MAC address, and, most importantly, the network name (SSID) it's connected to will be listed there. Although the password itself isn't printed in plain text for security reasons, the presence of the IP address confirms a successful connection.
☑️ Check the network report
If in the report you see that the connection status is "Disconnected" or the IP address starts with 169.254.x.x, this means the printer is not connected to the network. In this case, searching for the password in the device's memory is useless, as there is no active connection. You will need to reconfigure the connection using any available method.
Using a USB cable and HP Smart
If a wireless connection fails and the password is lost, a temporary wired connection can help. Using a USB cable like A-B (printer) you can connect the computer and HP LaserJet directly. This will allow the software to read the device's current settings.
Install the full software HP Smart or drivers from the support website. During initial setup, select "Update wireless connection" or "Switch from USB to Wi-Fi." The program may offer to use the current network settings saved on your computer.
During setup, the utility often displays the name of the network the printer is attempting to connect to. If this network profile is saved on your computer, Windows or macOS can automatically transfer the encryption key to the printer. This eliminates the need to manually enter the password.
⚠️ Attention: To use this method, your computer must already be connected to the same Wi-Fi network to which you want to connect the printer.
You can also sometimes access "Advanced Settings" -> "Device Settings" through the HP Smart interface. In rare cases, depending on the firmware version, this may display full security information, including the encryption type (WPA2/WPA3), which can help you guess the password if you know its variations.
Reset network settings to factory defaults
If none of these methods work, and the printer is connected to an unknown network or is malfunctioning, there's a radical but effective solution: resetting the network settings. This will return the Wi-Fi module to its default state, deleting all saved passwords and configurations.
To perform a reset on most models HP LaserJet Without a screen, simultaneously press and hold the wireless button and the cancel button (the cross) for 3-5 seconds. The lights should start flashing, indicating the recovery process has begun. After this, the printer will create its own access point.
After resetting, the device often goes into sleep mode Wi-Fi DirectIn this mode, the printer automatically broadcasts a Wi-Fi signal that can be connected to from a phone. The network name and password for connecting to the printer itself are usually indicated on the wireless information sticker located on the printer.
| Printer model | Reset button combination | Status indicator | Action after reset |
|---|---|---|---|
| LaserJet P1102w | Wireless + Cancel (3 sec) | Both indicators are flashing | Network search |
| LaserJet Pro M12a | Wireless connection (5 sec) | The blue indicator is flashing | Setup mode |
| LaserJet M203dw | Menu -> Network -> Restore Settings | The screen turns off and on | Reset TCP/IP |
| LaserJet Pro M402 | Wireless + Information | Pulsation of light | Ready to configure |
It's important to understand that after resetting, you'll still have to re-enter your router password. However, this method is useful because it clears any configuration errors that may have previously prevented the connection. The printer will become a "clean slate" for a new setup.
What to do if resetting doesn't help?
If, even after resetting the network settings, the printer still doesn't see the router or can't connect, the problem may not be the password. Check the frequency range: many older HP LaserJet models only operate in the 2.4 GHz band and don't see 5 GHz networks. Also, make sure MAC address filtering isn't enabled on the router.
Finding a password on other devices
Since the printer itself rarely displays the password in plain text, the most logical place to find it is where it's stored in a readable format. If a Windows laptop or Android smartphone has previously connected to this Wi-Fi network, the password can be retrieved from there.
On computers running Windows 10 and 11, this is done via the command prompt or network settings. If you've ever connected to the required network, the system has saved the key. This is the fastest way to find a forgotten password combination without interfering with the printer.
To view your saved password in Windows, you can use the following command in Terminal:
netsh wlan show profile name="Your_Network_Name" key=clearThe "Key Content" line will display the password you're looking for. After copying it, you can enter it into the printer menu or use it to connect other devices. Similar features are available in macOS's Keychain and in Android's Wi-Fi settings (via QR code).
Frequently Asked Questions (FAQ)
