Multifunctional device HP Laser MFP 135wr This compact solution is suitable for both office and home use, but its initial setup often raises questions for users accustomed to more modern interfaces. The main difference with this model is the lack of a full-color display, requiring alternative methods for entering wireless network settings. Unlike touchscreen devices, navigation is accomplished through a combination of buttons and status indicators.
To successfully integrate the printer into the local network, you will need to know the name of your network (SSID) and its password. The synchronization process can be performed in several ways: using a computer running Windows or macOS, or via a mobile app HP Smart or using technology WPS, if your router supports this feature. The method you choose depends on your hardware and operating system version.
It's important to understand that before making any changes to the network settings, the device must be powered on and ready. If you previously connected the printer via USB, the system may have automatically prompted you to set up a wireless connection. However, if you missed this step, you'll need to reset the network settings manually. This is a standard procedure that returns the communication module to network discovery mode.
Preparing equipment and resetting network settings
The first step is to properly prepare the peripheral device for wireless operation. Make sure the MFP is plugged in and the power indicator is solid. If the device was previously used on a different network or was purchased used, you should reset the network settings to factory defaults. This will clear saved profiles and allow the printer to rescan the airwaves.
To perform a reset on the control panel HP Laser MFP 135wr Locate the wireless connection button, usually marked with an antenna symbol. Press and hold this button and the cancel button (the cross) simultaneously for a few seconds until the lights start flashing. This combination activates setup mode, putting the Wi-Fi module in a waiting state.
After the reset, the wireless indicator should start flashing blue, indicating it's ready to pair. If the indicator isn't responding or remains solid, the network may already be configured, and you'll need to repeat the reset procedure for a longer period. In some cases, you'll need to completely power cycle the device after the reset for the changes to take effect.
⚠️ Attention: After resetting network settings, all previously connected computers will lose connection to the printer. You will need to reinstall the drivers or update the connection port at each workstation where this MFP is used.
Make sure your router broadcasts a network in the 2.4 GHz range, as most budget printer models, including 135wr, do not support the 5 GHz standard. If your router is dual-band and the network names are the same, temporarily separate them in the router settings or connect the printer to the 2.4 GHz guest network for initial setup.
Using a USB cable for initial setup
The most reliable way to configure a network for a model HP Laser MFP 135wr The best way to start is to use a wired USB connection. This method allows the software to automatically transfer the Wi-Fi router settings directly to the printer's memory, eliminating the need for complex manual input via buttons. You'll need a standard USB Type-B cable, which is often included, or any similar printer cable.
Connect one end of the cable to the USB port on the back of the printer and the other to an available port on your computer. The computer must be connected to the same Wi-Fi network to which you plan to connect the MFP. Run the driver installation file downloaded from the official website or use the included disc, if available.
During the installation process, select the "Wireless Connection" or "Network Connection" option. The program will detect the device via USB and prompt you to transfer the wireless network settings. At this point, the setup wizard will copy your Wi-Fi SSID and password and send them to the printer. Once the transfer is successful, the Wi-Fi indicator on the device's panel will turn blue, and you can disconnect the USB cable.
- 🔌 Connect the USB cable between your computer and the printer before installing the drivers.
- 📡 Make sure your laptop or PC is connected to the target Wi-Fi network, not a wired Ethernet connection (preferably).
- 🖥️ Follow the on-screen prompts, selecting the "Wireless Network" connection type.
- ✅ Wait for the successful setup message before disconnecting the cable.
⚠️ Attention: If an error occurs while transferring settings via USB, do not disconnect the cable prematurely. Wait until the process is complete or until a timeout message appears, otherwise the Wi-Fi module may be left in an undefined state.
This method is especially effective if your network name contains special characters or is hidden (not broadcast), since manually entering such parameters via the buttons on the panel 135wr is extremely difficult or impossible. Software takes on this complex task.
Setup via the HP Smart app on your smartphone
A modern and convenient way to set up is to use a mobile app HP Smart, available for iOS and Android. This method is ideal if you don't have a computer with a USB port or want to set up the printer from scratch. The app uses Bluetooth for initial device detection and Wi-Fi network data transfer, greatly simplifying the process.
To get started, download and install the app. HP Smart From your smartphone's app store. Enable location and Bluetooth on your phone, as without these permissions, the app won't be able to detect the printer in setup mode. Tap the "Add Printer" button (the plus sign) in the app and follow the on-screen instructions.
The app will ask you to select a printer from a list of available devices. Find the model in the list. HP Laser MFP 135w or similar. Once selected, the app will ask for your Wi-Fi network password. Unlike key entry, you simply enter the password using your smartphone's keypad, eliminating errors.
During the setup process, your phone may temporarily switch to a direct connection to the printer. This is normal. After the settings are transferred, the printer will attempt to connect to the router. Successful connection will be confirmed by a change in the device indicator and the printer appearing in the app's device list.
Connection using WPS (Wi-Fi Protected Setup)
Technology WPS allows you to connect your device to the network without entering a password, using either a physical button on the router or a PIN code. HP Laser MFP 135wr The push-button method is most effective if your router has a dedicated key. This is the fastest method, taking less than a minute.
Press the WPS button on your wireless router. Within two minutes, press and hold the wireless button on the printer's control panel for a few seconds until the light starts blinking. The printer will automatically detect the WPS signal and request the necessary encryption keys from the router.
If the connection is successful, the wireless indicator will stop blinking and turn solid blue. This means the device has acquired an IP address and is ready to use. If the indicator blinks continuously and then goes out, the connection has not been established, and you should repeat the procedure closer to the router.
| Wi-Fi indicator status | Meaning | Action |
|---|---|---|
| Turned off | Wireless connection is disabled | Press the Wi-Fi button |
| Flashing blue | Setup Mode / Network Search | Launch setup from your PC or phone |
| It's blue | Successful connection to the network | You can print |
| Flashing orange | Connection error / No signal | Check the password and distance to the router |
It's worth noting that the WPS method only works if the router supports this feature and it's enabled. In modern routers, the WPS button may be combined with the reset button or require a short press instead of a long press. Consult your router's manual for details.
Installing drivers and software
After successfully connecting the printer to the network, you need to install drivers on your computer so that the OS can correctly interact with the device. HP Laser MFP 135wr It is recommended to use the full driver package from the official website, as basic Windows drivers may not ensure the scanner operates over a network.
Go to the official HP support page and enter your device model. Download the "Full Feature Software and Driver" file. Run the installation and select "Wireless" as the connection type. The program will search for the printer on the network. If the printer is configured correctly, it will appear in the list of available devices.
During the installation process, you may be asked to confirm the device's use on the network. Agree to the terms, and the installation wizard will complete the port configuration. You will then be able to print documents from any device on the same network.
☑️ Checking driver installation
⚠️ Attention: Antivirus programs or firewalls sometimes block printer detection on the network. If the installation freezes during the search phase, temporarily disable the protection or add an exception for the HP installer.
Diagnostics and solution
Even with proper configuration, situations may arise where the printer becomes unavailable. A common issue is the router changing the printer's IP address during a reboot. To avoid this, it is recommended to assign an IP address to the device in the router settings (DHCP Reservation) or use a static IP address if the network allows it.
If the Wi-Fi indicator is blinking orange, this indicates a weak signal or an incorrect password. Try moving the printer closer to the router. Also, check that you're not using macros or special characters in the password, which the printer might interpret incorrectly. In such cases, it's best to change the router password to a simpler one (letters and numbers only) during setup.
Another common issue is a stuck print queue. If the document isn't sending, clear the print queue in Windows via Control Panel and restart the Print Spooler service. HP Laser MFP 135wr Also useful is the HP Print and Scan Doctor tool, which automatically finds and fixes most network errors.
What to do if the printer disappears from the network?
If your printer suddenly stops responding, try turning off the router, then the printer. Turn on the router, wait for it to fully boot up, then turn on the printer. This often resolves IP address conflicts.
Regularly check for firmware updates for your MFP. Manufacturers release updates that improve the stability of the Wi-Fi module and compatibility with new routers. You can update the firmware using the same app. HP Smart or via the printer's web interface (EWS) by entering its IP address in the browser.
Why doesn't the printer see the 5 GHz network?
Model HP Laser MFP 135wr This device is equipped with a Wi-Fi module that operates only in the 2.4 GHz band. 5 GHz networks use a different frequency and protocols, which are not supported by the device's hardware. You must connect to a 2.4 GHz network.
How to find out the IP address of a printer?
To print a network configuration report and find the IP address, press and hold the Wireless button on the printer control panel for approximately 5-10 seconds until the Ready light starts blinking, then release. The printer will print a report with the IP address listed in the Wireless section.
Is it possible to connect a printer to a hidden network?
Connecting to a hidden network (SSID not broadcast) on HP Laser MFP 135wr It's extremely difficult due to the lack of a display for entering the network name. It's recommended to temporarily enable SSID broadcast on the router, connect the printer, and then, if necessary, hide the network again (although this may break the connection).
What does the flashing orange light mean?
A blinking orange Wi-Fi light usually means the printer can't connect to the network. Possible causes include an incorrect password, a weak signal, the router blocking the connection by MAC address, or incompatible security standards (for example, an older printer and the newer WPA3 standard).
