Modern office tasks require mobility, and the presence of wires between the computer and the printer often becomes an unnecessary limitation. Wireless model HP Laser MFP 135w Allows you to place your equipment anywhere with network coverage, providing access to printing and scanning from any device in your home or office. The initial setup process may seem complicated at first, but with the right approach, it only takes a few minutes.
In this article, we'll cover all connection steps in detail, from preparing the equipment to installing drivers on the operating system. You'll learn how to properly reset network settings if your router has changed settings, and how to avoid common errors that occur when using the utility. HP Smart.
Before proceeding with the software, ensure that your laptop or desktop computer is already connected to the same Wi-Fi network to which you plan to connect the printer. This is a basic requirement, without which the software will not be able to automatically detect the device. Also, check that the cartridge is installed and the protective orange tape is removed from all internal mechanisms.
⚠️ Attention: Make sure your router is broadcasting a 2.4 GHz signal, as many printer models, including the HP 135w, don't support 5 GHz networks during initial setup. If you have a dual-band router with the same name for both networks, temporarily separate them or use a 2.4 GHz guest network.
Preparing equipment and checking network parameters
The first step is to physically prepare the device for wireless operation. Turn on the printer using the power button and wait until the warm-up cycle is complete, until the lights stop flashing. The device's control panel features a button with an antenna or wireless network icon—this is what activates the setup mode.
Press and hold this button for a few seconds until the wireless indicator starts flashing blue. This indicates that Wi-Fi Direct Or, setup mode is activated and the device is ready to search for a configuration. At this point, the printer creates its own access point or enters wait mode for a command from the computer.
At the same time, open the list of available Wi-Fi networks on your laptop. If you see a network with a name containing "HP-Setup" or your device model (e.g., "HP Laser MFP 135w"), the printer has successfully entered pairing mode. However, for a classic router setup, we need the indicator to simply blink, waiting for a connection to the existing network.
- 📶 Make sure your router is turned on and distributing internet.
- 🔋 Check that the printer is connected to a power source and is in a strong signal reception area.
- 💻 Your laptop must be connected to the same Wi-Fi network to which you want to connect the printer.
- 🛡️ Temporarily disable VPN services or proxy servers on your computer so that they do not block the search for devices on the local network.
Using the HP Smart app for automatic setup
The most modern and convenient installation method is to use the proprietary application. HP SmartIt's available for Windows 10/11, macOS, and mobile platforms. Download the app from the Microsoft Store or the manufacturer's official website to ensure you have the latest drivers.
After launching the app, click the "Add Printer" button or the plus sign. The system will automatically scan the network. If the printer is in setup mode (the indicator light is blinking), the app will detect it and prompt you to continue. You'll need to select your home Wi-Fi network from the list and enter the password.
During the setup process, the app will transfer network settings directly to the printer. At this point, the device's indicator light may stop flashing and turn solid blue, indicating a successful connection. The app will also prompt you to register the device and set up automatic firmware updates, which is recommended to fix any future bugs.
⚠️ Attention: If the HP Smart app doesn't find your printer, try temporarily enabling Bluetooth on your laptop. Some modern software versions use Bluetooth Low Energy for the initial handshake before transmitting Wi-Fi data.
Setup via WPS (Wi-Fi Protected Setup)
If your router supports WPS, you can significantly simplify the connection process by avoiding manual password entry. This method is ideal when the Wi-Fi password is too complex or you don't want to manually enter it on each device. Check for a physical WPS button on your router.
Press and hold the wireless button on the HP 135w printer until the light starts blinking. Then, within two minutes, press the WPS button on the router. The devices will automatically exchange encryption keys, and the printer will connect to the network.
The printer's indicator light will stop flashing and turn solid, confirming a successful connection. This method only works if WPS isn't disabled in your router settings, which is sometimes done for security reasons.
What to do if there is no WPS button on the router?
If there's no physical button, log into your router's web interface (usually 192.168.0.1 or 192.168.1.1) and find the Wireless or Wi-Fi section. There should be a software button for activating WPS. Press it in the interface, then initiate WPS mode on the printer.
Manual installation of drivers and software from the official website
In cases where automatic methods don't work, or you require a full suite of scanning and management utilities, manual installation is required. Go to the official HP support page and enter your model number. HP Laser MFP 135w in the search field. Select your operating system from the drop-down list.
You will be prompted to download the full package of drivers and software. The installer file usually has the extension .exe for Windows or .dmg for macOS. Run the downloaded file and follow the on-screen instructions. It's important not to connect the device via USB unless explicitly instructed to do so by the installer.
During installation, the program will prompt you for a connection type. Select "Wireless" or "Wi-Fi." If the program prompts you to connect a USB cable for the initial network settings transfer, do so. You can disconnect the cable after successful setup. The program will automatically reconfigure the print ports to network ports.
