Changing internet providers or purchasing a new router inevitably poses the task of reconfiguring all network devices in the home or office. Printers, especially laser models HP LaserJet, are often the most difficult to navigate, as they lack a full touchscreen for quickly entering a new password. The standard procedure requires a complete reset of the old network settings and placing the device in discoverable mode.
There are several proven methods for successfully integrating a printing device into a new infrastructure. The specific method you choose depends on your printer model, availability, Ethernet port on the case and operating system of the computer from which control is planned. Modern technologies simplify this process, but require strict adherence to the correct sequence of actions.
In this guide, we'll detail the steps for various scenarios. You'll learn how to use mobile apps, the web interface, and physical buttons for quick migration. Proper setup will ensure stable printing from any device on your local network.
Preparing equipment before changing the network
Before you begin working with the software, you must ensure that the hardware is physically ready. The printer must be plugged in and ready. Make sure the cartridge is installed and there is paper in the tray, as some models do not activate. wireless module in case of errors in the submission of material.
You'll need to know the exact name of the new network and its password. Passwords are often case-sensitive, so check your keyboard layout beforehand. If your router broadcasts a signal on both 2.4 GHz and 5 GHz frequencies under the same name, make sure your control device (smartphone or PC) is connected to the 2.4 GHz band, as most older models do. LaserJet do not support the 5Hz range.
⚠️ Note: If your router is configured for client isolation, the printer will not be able to communicate with the computer even when connected to Wi-Fi. This feature is often enabled on guest networks.
☑️ Check before setup
It's important to temporarily disable VPN and antivirus firewalls on the computer you'll be using for setup. Aggressive security settings may block the printer from being found on the local network, resulting in a connection error. After successful setup, you can restore the protection.
Resetting the HP Printer Network Settings
A key step in migrating to a new network is clearing the device's memory of old connection profiles. While the memory still contains data from the previous router, the printer will attempt to connect to it, ignoring new commands. For models with touch screen The process looks the most.
On the device's display, go to the settings menu, often indicated by a gear icon. Find the section related to network or wireless connection. You'll need to find the option "Restore network settings" or "Reset network settings." Confirming this action will reset the network module to its factory settings.
For models without a screen, such as the series HP LaserJet Pro M15 or M28, a button combination is used. Typically, you need to simultaneously press the wireless button and the cancel button (cross) for a few seconds until the lights flash. On older models, for example, P1102w, you may need to hold the Wi-Fi button until the indicators stabilize.
Network status indication
A solid blue wireless indicator means the connection is active and stable. Blinking means the device is searching for a network or transferring data. Off means the Wi-Fi module is disabled or has failed. An orange indicator often indicates a connection error or low signal strength.
After the reset, the wireless indicator should start flashing blue. This means the device has entered pairing mode and is ready to accept new login credentials. local network.
Using the HP Smart app to set up
The most universal and modern way of connection is to use the utility HP SmartIt's available for Windows, macOS, Android, and iOS. The app automatically scans the network for new devices and provides step-by-step instructions. Download the official version of the app from the Microsoft Store, the App Store, or the manufacturer's website.
Launch the app and click the "Add Printer" button. The program will ask you to enable Bluetooth on your smartphone or computer to detect the device for the first time. Make sure your control device is connected to the same Wi-Fi network to which you want to connect the printer.
During setup, the app will transfer the SSID and password directly to the printer. This eliminates manual entry errors. If the printer is not found, select the "Printer not found" option and follow the instructions to connect via USB or a temporary access point.
For devices with a display, the process can begin immediately after selecting a network from the list on the printer's display. In this case, the app will act as a confirmer, and all you need to do is tap "Connect" on your smartphone's screen. This is especially convenient when you need to enter a complex password that's difficult to type using the printer's keys.
Setup via USB cable and Ethernet
If you can't establish a wireless connection, use a wired connection. Connecting via USB cable Allows the computer to temporarily "acquaint" the printer with the network settings. You'll need a USB-A cable, which is often included in the kit, but may need to be purchased separately for laser models.
Connect the printer to your computer via USB. Run the driver installer from the disc or the package downloaded from the HP website. During the installation, select "Wireless" as the connection type, and when prompted to connect the cable, do so. The program will transfer the network settings via the cable and then prompt you to disconnect it.
An alternative option for office models LaserJet — Using an Ethernet port. Connect the printer directly to the router with a LAN cable. This will automatically assign an IP address to the device and make it accessible on the network. You can then configure the Wi-Fi connection via the web interface if you need to switch from a wired connection to a wireless one.
| Connection method | Necessary equipment | Complexity | Speed of setup |
|---|---|---|---|
| HP Smart (Wi-Fi) | Smartphone/PC, Bluetooth | Low | High |
| USB cable | USB AB cable | Average | Average |
| Buttons (WPS) | Router with a WPS button | Low | High |
| Web interface | PC, Ethernet cable | High | Low |
Using a cable ensures stable data transfer during the configuration phase. This is especially important in offices where multiple wireless networks can interfere. After setting up the cable, you can disconnect it, and the printer will continue to operate wirelessly.
Connecting via WPS (Wi-Fi Protected Setup)
Many modern HP routers and printers support WPS technology, which allows you to connect devices without entering a password. This method is ideal if you don't know your Wi-Fi password or it's too complex. Your router should have a physical WPS button or a corresponding function in the web interface.
Find the wireless button on the printer's panel. Press and hold it for 2-3 seconds until the light starts flashing. Within two minutes, press the WPS button on your router. The devices will automatically find each other and exchange encryption keys.
If your printer doesn't have a dedicated WPS button, the process may differ. On some models LaserJet You need to enter the wireless menu and select "Wi-Fi Protected Setup." After selecting this option, you will have a limited time to activate the feature on your router.
It's worth noting that the WPS method is considered less secure according to modern data protection standards, as it uses a vulnerable PIN code protocol. While this is acceptable for a home network, in the corporate segment with high security requirements, manual password entry via HP Smart.
Troubleshooting connection and visibility issues
A common issue after changing networks is that the computer doesn't see the printer, even though the printer lights are green. This happens because the devices are on different subnets or the isolation feature is enabled. Make sure both devices are connected to the same guest or primary network.
If your printer is showing as "Offline," try updating the print port in your system. Go to "Devices and Printers" and select your printer. HP LaserJet, click "Printer Properties" and go to the "Ports" tab. Make sure the port with the correct IP address for the new network is selected.
In some cases, statically assigning an IP address can help. Knowing the printer's MAC address (found on the sticker on the back), you can assign a permanent IP address to it in the router settings. This will prevent situations where the router changes the device's address after a reboot and the driver loses connection.
⚠️ Note: Router interfaces and printer firmware versions are constantly being updated. The menu item locations may differ from those described. If you don't find the option you need, please refer to the documentation for your specific model or the official support website.
It's also worth checking the Windows print service. Click Win + R, enter services.msc and find the Print Spooler service. It should be running and in automatic mode. Failures in this system service often mimic network problems.
Setting up printing from mobile devices
Once your printer is successfully connected to a new Wi-Fi network, you can set up printing from your smartphone. Apple devices use the technology AirPrint, which doesn't require driver installation. Just make sure your iPhone or iPad is on the same network and select "Print" from the menu of any app.
For Android and advanced functionality on iOS, it is better to use the app HP Smart or service MopriaThey allow you to scan documents directly to the cloud or your phone, as well as monitor toner levels. Mobile printing is especially convenient for quickly printing photos or tickets.
If your mobile device doesn't see your printer, check your router settings. AP Isolation prevents devices within the same Wi-Fi network from communicating with each other. Disabling this feature in your router's wireless settings usually resolves the issue.
Print from anywhere in the world
To print remotely, set up HP ePrint. Register your printer on the HP Connected website, get a unique email address for your device, and send documents to it as an attachment. The printer will print the email, even if you're located in another country.
Now it's yours HP LaserJet Fully integrated into the new network. Check for firmware updates regularly through the app, as they often contain wireless module bug fixes and improved compatibility with new routers.
Why won't my HP printer connect to 5GHz Wi-Fi?
Most models HP LaserJet, especially budget and mid-range models, are equipped with modules that operate only in the 2.4 GHz band. They are physically unable to see 5 GHz networks. Solution: in the router settings, separate the networks into different names (SSIDs) or ensure mixed mode support is enabled, although the printer will still connect to the 2.4 GHz band.
How do I find my printer's IP address after changing my network?
On models with a display, press the wireless button or go to the network menu; the IP address will be displayed there. On models without a display, press and hold the wireless button and the information (i) button simultaneously for 3 seconds. The printer will print a report with the current address listed in the IPv4 section.
What should I do if I forgot my Wi-Fi password during setup?
If you have a Windows computer already connected to this network, you can view the saved password. Open the Command Prompt (cmd) and enter the command: netsh wlan show profile name="Network_Name" key=clearYour password will be displayed in the "Key Contents" field.
Can I connect a printer to a guest Wi-Fi network?
Technically, this is possible, but not recommended. Guest networks often have restrictions on communication between devices (client isolation), which will prevent the computer from printing. Furthermore, changing the guest network password (which is often done automatically) will cause the printer to lose connection again.
