Setting up wireless printing in a home office or small workgroup makes document management much easier. Model HP Laser MFP 135a It's a compact laser solution that, when properly configured, allows printing from any device within network coverage. However, the initial setup process often presents difficulties for users due to the lack of a standard display on the control panel.
Unlike older models in the series, this one uses a simplified interface that requires a specific approach to entering router parameters. Wireless connection This provides portability and eliminates unnecessary cables, but requires precise pairing sequence. An error at any stage can result in the computer simply not recognizing the device.
In this guide, we'll cover every setup step in detail, from preparing the hardware to the intricacies of working with drivers in the Windows operating system. You'll learn how to activate configuration mode, select the correct connection method, and troubleshoot common connection errors. The key point is to precisely adhere to the timings when switching the WiFi module operating modes.
Preparatory stage and compatibility check
Before installing the software, you need to make sure your infrastructure is ready to work with the printer. The device supports the following standards: 802.11b/g/n, which means compatibility with the vast majority of modern home routers. Make sure your laptop or desktop PC is connected to the same network to which you plan to connect the MFP.
It's important to know your network's SSID (name) and password. If you're using a corporate network with a hidden SSID or a complex web portal authentication system, automatic setup may not work. In such cases, you'll need to manually enter the settings or use the WPS method, if supported by your router.
It's also worth checking whether the wireless module is enabled on the device itself. On the panel HP Laser MFP 135a A special button with a corresponding icon is responsible for this. The indicator should either blink, indicating setup mode, or remain solid, indicating a successful connection.
⚠️ Important: Make sure you're not using a Guest Network with client isolation. In such networks, devices won't be able to see each other, and network printing will be impossible.
For stable operation, it is recommended that the router's frequency range be configured correctly. Although the device supports 2.4 GHz, some modern routers combine bands by default or use only 5 GHz, which can cause compatibility issues.
Activating wireless network setup mode
The most crucial step is putting the printer into connection standby mode. Since the 135a model doesn't have a full-screen display, the WiFi button blinks to indicate its status. First, make sure the printer is turned on and there's paper in the tray.
Press and hold the wireless button on the control panel for a few seconds until the indicator light starts flashing. This usually takes about 3-5 seconds. A flashing indicator light means configuration mode activated and the device is broadcasting a pairing ready signal.
If the indicator light turns solid immediately, it means the printer is attempting to connect to a previously saved network. In this case, you need to reset the network settings. To do this, turn off the device, press and hold the wireless button, and then turn it on. Keep holding the button until the indicator light starts flashing.
- 🔹 Press the WiFi button on the control panel.
- 🔹 Hold it for 3-5 seconds until the indicator starts flashing.
- 🔹 If the light is steady, reset the network settings using a combination of buttons.
- 🔹 Make sure the indicator is flashing slowly (search mode).
Once enabled, you have a limited time to run the setup program on your computer. If the process takes too long, setup mode may automatically disable to save power, and you'll have to repeat the process.
Installing drivers and software
For full functionality HP Laser MFP 135a In wireless mode, you must install the full driver package. Don't rely on Windows Update's automatic driver installation, as it often only provides a basic print driver without network configuration utilities.
Download the latest version of the software from the manufacturer's official website. You will need a file with a full name containing Full Feature Software and DriverRun the installer and follow the on-screen instructions. When asked for a connection type, select "Wireless."
During installation, the program will search for available devices. If the printer is in setup mode (the indicator light is blinking), the installer will prompt you to select it from the list or connect via USB cable to transfer network settings. The latter option is often more reliable if the automatic search fails.
☑️ Check before installing the driver
If you selected the USB settings transfer method, the program will prompt you to connect the cable. Once the settings are transferred, you can disconnect the cable—the rest of the work will be done over the air. The driver will complete the installation by detecting the device's IP address on the local network.
Setup via WPS
An alternative and often faster way to connect is to use technology WPS (Wi-Fi Protected Setup)This method allows you to connect devices without entering a password, simply by pressing a button on the router. Check if your router has a physical WPS button.
Press the WPS button on the router. Within two minutes, press and hold the wireless button on the printer. HP Laser MFP 135a until the indicator starts blinking. The device will automatically detect the router's signal and exchange encryption keys.
A successful connection will be indicated by a steady glow of the WiFi indicator. If the indicator continues to flash or flashes at a different frequency, the connection has failed. This may be due to a timeout or incompatible encryption methods.
⚠️ Important: The WPS method will not work if your router has this feature disabled in its security settings or is using an encryption type that does not support WPS (for example, only WPA3 without mixed mode support).
In some cases, routers require a WPS PIN, which can be found on a sticker on the back of the device or in the documentation. However, for printers, the push-button method is more commonly used, which significantly simplifies the process.
Manually configuring the IP address and network
In corporate networks or when using complex router settings, manual IP address configuration may be required. By default HP Laser MFP 135a Obtains an address automatically via DHCP. If there is no DHCP server on your network, printing will not work.
For manual configuration you will need a utility HP Printer Assistant Or the web interface, if available. Enter a static IP address, subnet mask, and gateway that match your subnet. This will ensure a consistent address, which is important for stable driver operation.
A common problem is the router changing the address range. If the router distributes addresses in the range 192.168.0.x, and the printer "remembered" the network settings 192.168.1.x, they won't see each other. In this case, a full network reset on the printer helps.
| Parameter | Default value | Recommended value | Description |
|---|---|---|---|
| IP mode | Auto (DHCP) | Auto (DHCP) | Automatically obtain an address from the router |
| Protocol | IPv4 | IPv4 | Basic protocol for local printing |
| SSID | Not set | Your network name | Wireless Network ID |
| Channel | Auto | 1, 6 or 11 | The least crowded channels in the 2.4 GHz band |
What should I do if my printer doesn't receive an IP address?
If the LED is on but there's no printing, check the client table in the router. The device may be blocked by MAC address or the DHCP address pool may be exhausted. Try rebooting the router.
Diagnostics and troubleshooting
Even with proper configuration, situations may arise where printing is impossible. The first step should always be checking the device's status in the operating system's "Devices and Printers" window. If the status is "Disconnected" or "No Connection," check the device's physical accessibility.
Use the built-in HP diagnostic tool, which is installed with the driver. It can automatically detect and fix common errors, such as a stuck print queue or an incorrect connection port.
Often, the problem lies with a firewall or antivirus program blocking the printer's network port. Try temporarily disabling the protection to see if the connection is restored. If so, add an exception for the printing app in the security settings.
- 🔹 Check if the WiFi indicator is on steadily.
- 🔹 Make sure your computer and printer are on the same subnet.
- 🔹 Try pinging the printer's address via the command line.
- 🔹 Restart your router and printer one by one.
If nothing helps, perform a network reset on the printer (hold down the buttons while turning it on) and repeat the setup procedure from the beginning, being careful when entering the WiFi password (it is case sensitive).
