Mobile printing has long ceased to be a luxury and has become a standard for office and home work. Model HP Laser MFP 135w It has become one of the most popular budget solutions, but initial wireless connection setup often raises questions among users. The main difficulty lies in the lack of a touchscreen and the need to manually enter parameters through the control panel.
Unlike more advanced models, this laser printer requires precise steps to successfully integrate into the network. Selecting the wrong Wi-Fi mode will prevent your phone from detecting the device. In this article, we'll cover the pairing process in detail, focusing on the nuances of working with routers of different frequency bands.
Equipment preparation and compatibility testing
Before you begin setup, you need to make sure your network equipment meets the printer's technical requirements. Key point: the device only supports the standard 802.11b/g/n in the range 2.4 GHzIf your router operates exclusively on the 5 GHz frequency or is split into two separate networks, your phone may not find the printer even if you follow the correct steps.
You should also prepare the printer itself. Make sure the cartridge is installed, the lid is closed, and paper is loaded into the tray. The control panel lights should be solid and not flashing to indicate an error. For setup, you'll need a smartphone with Wi-Fi enabled and the app installed. HP Smart or the standard printing service of your OS.
Make sure you know your wireless network password. In some cases, especially when using corporate networks or complex home configurations with guest zones, standard connection methods may be blocked by the router's security settings.
⚠️ Important: Make sure your router doesn't use MAC address filtering in blocking mode. If this feature is enabled, the printer will not be able to access the network, even with the correct password.
Activating the setup mode on the printer panel
The first step is to put the device into connection standby mode. In the control panel HP Laser MFP 135w Find the button with the wireless network icon. Press and hold it for a few seconds until the indicator light next to it starts flashing blue. This means the Wi-Fi module has entered configuration mode.
It's important not to confuse the short press, which simply turns the wireless module on or off, with the long press, which enters setup mode. If the indicator light is blue but not flashing, the printer is already connected to a network and needs to be reset. To do this, hold down the wireless button and the cancel button (red cross) simultaneously for about 5 seconds.
After successfully entering setup mode, the indicator light should begin blinking slowly. This indicates that the printer has created a temporary access point or is waiting for a command from the app to transfer router settings. Now you can proceed to using your smartphone.
What should I do if the indicator light is flashing too fast?
Rapid blinking often indicates a hardware error in the Wi-Fi module or a critical firmware failure. Try unplugging the printer for 30 seconds and then repeating the process. If that doesn't help, you'll need to reset the printer settings via the service menu (if available) or reflash the firmware via USB.
Setup via the official HP Smart app
The most reliable way to set up HP Laser MFP 135w - using the utility HP SmartDownload the app from Google Play or the App Store. After installation, launch it and sign in to your HP account (registration is required for cloud features).
Tap the "Add Printer" button or the plus icon in the corner of the screen. The app will ask you to enable Bluetooth and location services on your phone—these are necessary to find the device. Once the printer is found, select it from the list. The app will then automatically scan for available Wi-Fi networks and prompt you to select yours.
Enter your router password. At this point, your phone will transfer data directly to the printer. This process takes about a minute. If successful, the indicator light on the phone will stop flashing and turn solid blue, and the app will show "Ready."
☑️ Checklist for successful setup
Alternative method: WPS connection
If your router supports the technology WPS (Wi-Fi Protected Setup) significantly simplifies the process by eliminating the need to manually enter a password. This method is especially convenient if you don't remember a complex security key or are worried about entering it incorrectly.
Press the WPS button on your router. Within two minutes, press and hold the wireless button on the printer. HP Laser MFP 135w until the indicator starts blinking. The devices will automatically exchange encryption keys.
Please note that many modern routers have this feature disabled by default for security reasons. Furthermore, WPS does not work with networks using enterprise encryption or a hidden SSID.
Connecting Android and iOS devices
Once the printer is connected to the network, printing from the phone is carried out using standard system tools. Android devices (version 4.4 and above) use the service Mopria or built-in printing subsystem. iOS the technology works AirPrint, which does not require installation of additional drivers.
Open the document or photo you want to print. Tap the "Share" menu or the three dots, and select "Print." The system will search for devices on the network. If your phone and printer are on the same subnet, HP Laser MFP 135w will appear in the list of available ones.
In some cases, especially on Android, you may need to install the HP Print Plugin. The system will prompt you to do this the first time you launch the print feature. Follow the on-screen instructions to complete the installation.
Solution and indicator table
Setup doesn't always go smoothly the first time. Issues can arise due to a static IP address, a weak signal, or protocol conflicts. Below is a table to help diagnose the Wi-Fi module's status based on the color and blinking pattern of the indicator.
| Indicator status | Meaning | Action |
|---|---|---|
| Turned off | Wireless connection is disabled | Press the Wi-Fi button once |
| Flashing blue (slowly) | Setup mode (ready to connect) | Launch the HP Smart app |
| It's blue | Connected to the network | You can print |
| Flashing blue (fast) | Connection error or searching for network | Check your router password and settings |
| Flashing orange | Network error or factory reset | Perform a network reset and set up again |
If the printer isn't visible on the network even though the indicator light is blue, check if AP Isolation is enabled in your router settings. This feature prevents devices on the same Wi-Fi network from communicating with each other, making printing impossible.
⚠️ Note: Router interfaces and app versions are subject to update. If the menu items described differ from yours, please refer to the router manufacturer's documentation or the app's help section.
Frequently Asked Questions (FAQ)
Can the HP Laser MFP 135w be connected to a hidden Wi-Fi network?
Directly connecting to a hidden network (Hidden SSID) through the standard setup menu is difficult because the printer cannot display a list of networks to select. In this case, it is recommended to temporarily make the network visible, configure the settings, and then hide the SSID again. An alternative option is to use WPS if your router supports connecting to hidden networks using this method.
Why does the phone see the printer, but printing doesn’t work?
Most often, the problem is that the phone is connected to the router's guest network, and the printer is connected to the main network (or vice versa). Make sure both devices are on the same frequency band (e.g., 2.4 GHz) and the same subnet. Also, check if your phone's antivirus software is blocking access to local devices.
How do I reset the network settings on an HP 135w printer?
To reset your network settings to factory defaults, press and hold the Wireless and Cancel buttons simultaneously for 5 seconds. The indicators will flash, and your Wi-Fi settings will be cleared. You will then need to reconnect.
Does printing via USB cable work if Wi-Fi is not configured?
Yes, the 135w model supports connection via a USB Type AB (printer) cable. However, to use it from an Android phone or iPhone, you'll need a special USB-OTG adapter and PTP/MTP support on the device. The HP Smart app also supports a wired connection for initial setup.
