Connection multifunctional device to your home network opens up the possibility of printing documents and scanning images from any gadget within the router's range. Model HP Laser MFP 135r The device features a compact design and lacks a built-in touchscreen, making setup impossible through the device's menu. Users often encounter difficulties precisely because they need to use a computer or smartphone for initial configuration of the communication module.
The main difficulty is that the device must receive the correct network parameters to begin the process. Unlike the older models in the series, there is no quick connect button, so the entire process is software-dependent. The exact sequence of actions guarantees successful integration of the printer into the infrastructure of your office or apartment.
In this article, we'll cover every installation step in detail, from preparing the equipment to troubleshooting common connection errors. You'll learn how to use the HP Smart utility correctly and what to do if the automatic search doesn't yield results. Proper setup will allow you to forget about wires and use wireless interface at full speed.
Equipment preparation and compatibility testing
Before you begin, make sure your router is working stably and is distributing the network in the 2.4 GHz range. Model HP Laser MFP 135r, like many budget laser devices, may not support modern Wi-Fi 6 standards or the 5 GHz frequency without prior router configuration. Range compatibility is a critical factor for success.
You'll also need a computer running Windows or macOS, or an Android or iOS smartphone with the app installed. It's important that the device you're using for setup is connected to the same Wi-Fi network you plan to connect the printer to. A USB cable is only needed in rare cases of manual IP address configuration; the standard procedure is done over the air.
Check that there are cartridges and paper in the tray, as the device may not enter network setup mode if there are no consumables. The control panel indicators should be steady, indicating no mechanical errors.
⚠️ Important: If your router uses the "Guest Network" feature or Client Isolation, the printer will not be able to communicate with the computer. Make sure both devices are on the same primary subnet.
- 📶 Make sure your router is broadcasting a 2.4 GHz signal.
- 💻 Prepare a PC or smartphone with internet access.
- 📄 Check that there is paper and toner in the trays.
- 🔌 Make sure the printer is plugged in and turned on.
Resetting the printer's network settings
If the device was previously used on a different network or attempted to connect with incorrect settings, you will need to perform a reset. This will clear saved profiles and restore network module to factory settings. For the model HP Laser MFP 135r The procedure is performed by a combination of buttons on the control panel.
Press and hold the Wireless button and the Cancel button (the cross) simultaneously for 5 seconds. The lights should flash, confirming the settings have been reset. The printer will then reboot the network adapter.
☑️ Pre-reset check
After the reset, the Wi-Fi indicator will begin flashing blue, indicating the device is in setup mode. In this state, the device creates its own access point or waits for commands from the computer. Do not turn off the device until the reset is complete.
Using the HP Smart app to set up
The most modern and manufacturer-recommended method is to use the app. HP SmartIt's available in the Microsoft Store for Windows 10/11, the App Store for macOS, and the mobile app stores for Android and iOS. The app automatically detects new devices on your local network.

Application menu path: Home → Add Printer → Select Device → Wi-Fi SetupThe app will request your Wi-Fi network password and transmit it directly to the printer. This method is the most secure, as it eliminates manual entry errors and driver issues at the initial stage.
What should I do if the app doesn't see the printer?
Make sure Bluetooth and location services (for mobile devices) are enabled on your computer. Also, check to see if your antivirus or firewall software is blocking the HP Smart app. Sometimes, temporarily disabling your VPN connection can help.

Configuration via the web interface (EWS)
For advanced users, a setup method via the embedded web server is available, but it requires the printer to already have an IP address or to be temporarily connected via USB. If automatic setup fails, this method allows you to manually enter static IP and DNS parameters.
Enter the printer's IP address in the browser's address bar. By default, if DHCP hasn't assigned an address, the device may have an address like 192.168.1.x. In the navigation menu, go to the "Network" tab.
| Parameter | Description | Recommended value |
|---|---|---|
| IPv4 Configuration | Address acquisition mode | Automatic (DHCP) |
| SSID | Wireless network name | Your network name |
| Security Mode | Encryption type | WPA2-Personal |
| Passphrase | Access password | Wi-Fi password |
After making changes, be sure to click "Apply" or "Save." The printer will reboot its network module and attempt to connect to the specified access point. This method is useful on corporate networks with a hidden SSID.
Installing drivers and software

Solving common connection problems
A common issue is a mismatch between the router and printer's frequency ranges. If the router broadcasts a network with the same name (SSID) for both 2.4 GHz and 5 GHz, the printer may attempt to connect to an unsupported frequency. Temporarily separate the networks in the router settings.
It's also worth checking your Windows firewall or antivirus settings. They may be blocking the printer from being detected on the network. Add the HP app and printing services to the exception list.
If the Wi-Fi indicator continues to flash, try moving the printer closer to the router to rule out signal strength issues. Walls and household appliances can cause significant interference with the laser module.
Why is my printer not in the list of devices?
Make sure your computer and printer are connected to the same network (not a guest network). Check if Bonjour or SLP is enabled in your router settings. Sometimes, rebooting both the router and printer simultaneously helps.
Is it possible to connect a printer without the Internet?
Yes, you can use Wi-Fi Direct. In this case, the device creates its own network, which the computer connects to. However, initial access to the HP repositories is still required to install the drivers.
How to find out the IP address of a printer?
Press and hold the wireless button on the printer for 5 seconds. The printer will print a network configuration report, which will display the current IP address.
Does this model support cloud printing?
Yes, you can print from anywhere in the world with internet access using HP ePrint and the HP Smart mobile app, as long as you have the correct initial setup.
