Modern laser printers, such as the model HP Laser 135wr, have long since ceased to be mere office equipment that required a cable connection to a computer. Wireless printing has become a standard of convenience, allowing you to instantly send documents or photos directly from your smartphone, bypassing the hassle of cables. However, initial setup wireless connection often raises questions among users accustomed to simpler operating schemes.
Activating network functions on this model has its own unique features, due to the lack of a touchscreen and the presence of a button-only interface. You'll need to carefully monitor the LED indicators and enter your home network settings correctly. In this article, we'll cover all connection steps in detail, from enabling broadcast mode to printing your first document via the app. HP Smart.
Preparing the HP 135WR printer for network connection
Before attempting to sync the device with the router, ensure the printer is physically ready for use. Make sure the cartridge is installed, paper is loaded in the tray, and the device is plugged in. The power light on the control panel should be illuminated, and after a short while, the ready light will illuminate.
The key point for the model 135wr is to put the wireless module into active search mode. Since there is no on-screen menu, all controls are handled via the Wireless button on the panel. Press and hold this button for a few seconds until the wireless indicator starts flashing blue. This indicates that setup mode activated.
⚠️ Important: If the wireless network indicator is solid blue, this means the printer is already connected to a network. To connect to a new router, you must first reset the network settings by holding down the wireless and cancel buttons simultaneously for a few seconds until the indicators flash.
Once search mode is activated, the device is ready for pairing. Your phone and printer are now in the state required to begin configuration. Do not turn off the device during the setup process, as this may interrupt the recording of network settings.
Using the HP Smart app for automatic setup
The most reliable and manufacturer-recommended method is to use proprietary software. HP SmartThis app is available for Android and iOS operating systems and allows you to automatically detect a printer on your local network. Download and install the app from the official store (Google Play or App Store) on your smartphone.
Launch the app and sign in to your HP account, or register if you don't already have one. Click the button to add a new printer (usually a plus sign or the words "Add Printer"). The app will ask you to enable Bluetooth on your phone to search for the device—this is necessary for initial data exchange.
When the app finds your HP Laser 135wr, it will prompt you to select your home WiFi network from a list. You will be asked to enter the router password. The app will automatically transfer this data to the printer via Bluetooth. Once the data is transferred, the printer's indicator will stop flashing and turn solid blue, indicating a successful connection.
☑️ HP Smart Connection Checklist
Setting up via Wi-Fi Direct mode without a router
If you don't have access to a home router or you're in a location where using the main network isn't possible, the model 135wr Supports Wi-Fi Direct technology. This mode creates a direct connection between your phone and printer, bypassing any intermediate hardware. To activate, press and hold the Wi-Fi Direct button on the control panel (or the button combination specified in the instructions, often the wireless button).
After enabling Wi-Fi Direct, the printer will begin broadcasting its own signal. A network name beginning with "HP-Setup" or "Direct-HP" will appear in the list of available networks on your smartphone screen. Connect to this network. You can find the default password by printing a configuration report.
To print the report, press and hold the Resume button (triangle) on the printer control panel for a few seconds. On the printed sheet, find the Wi-Fi Direct section and check the value. Wi-Fi Direct PasswordEnter this password when connecting your phone to the printer network.
| Parameter | Description | Where to find |
|---|---|---|
| Network name (SSID) | A unique name for your printer | Configuration Report / Phone Screen |
| Password | Access code (8 or more characters) | Configuration Report (Wi-Fi Direct Section) |
| Indicator | Connection status signal | Control panel (blinks when searching, lights when connected) |
⚠️ Note: When using Wi-Fi Direct mode, your phone may temporarily lose internet access as it switches to the printer's network. Some modern smartphones can work with two Wi-Fi networks simultaneously, but this depends on the phone model.
Print documents and photos from Android and iPhone
Once successfully connected, regardless of the chosen method (router or Direct), the printing process is similar. Open the document, photo, or web page you want to print. In the app menu (usually the three dots or the "Share" button), select "Print."
The system will prompt you to select a printer. If you're using Android, you may need to install a plugin. HP Print Service Plugin, which is often installed automatically or requested by the system. On Apple devices (iOS), AirPrint technology is built into the system and does not require additional drivers.
In the preview window that opens, you can adjust the settings: select the number of copies, page range, orientation (portrait or landscape), and paper size. For the model 135wr It's important to ensure that A4 is selected, as this is the default format for this device. Click the print button, and the document will be sent to the queue.
What to do if the print is stuck?
If the document has been sent but the printer is silent, check the print queue on your phone. Sometimes, restarting the print service in your phone's settings or reconnecting to the WiFi network helps. Also, make sure your computer, if connected to the same printer, isn't displaying a printer error message blocking the queue.
Diagnosing wireless connection problems
Despite the simplicity of the technology, glitches sometimes occur. The most common issue is the printer "losing" the network or not detecting the router. This can happen if the router has changed its communication channel or if the security settings have been updated. In such cases, restarting the setup process through the app helps. HP Smart.
Another common cause is frequency separation by the router. Many modern routers combine 2.4 and 5 GHz networks under a single name, which can confuse older devices. Try temporarily separating the networks in the router settings by giving them different names, and connect your phone and printer strictly to the 2.4 GHz network.
Check your router's firewall or antivirus settings if the printer is visible on the network but isn't responding to print requests. Sometimes blocked ports can prevent data transfer. Also, make sure the printer itself isn't in "Eco-silence" or deep sleep mode, which disables the WiFi module to save power.
Frequently Asked Questions (FAQ)
Can the HP 135wr be connected to a 5GHz network?
No, the model does not include a wireless module. HP Laser 135wr Only supports the 802.11b/g/n standard, which operates in the 2.4 GHz frequency range. Connecting to a 5 GHz network is technically impossible.
Do you need internet to print from your phone?
Internet access is not required if you use Wi-Fi Direct. If the printer is connected to a router, then internet access is also not required for printing within a local network; only a working router is required. However, an internet connection is required for initial setup via the HP Smart app.
How to find out the IP address of a printer?
You can find the IP address by printing a network configuration report (by holding down the wireless or resume button, depending on the firmware version). The address is also displayed in the HP Smart app under Printer Information.
Does this model support driverless printing?
Yes, when connected via Wi-Fi Direct or a network, modern mobile operating systems (Android 4.4+ and iOS) use built-in protocols (Mopria or AirPrint), which allows you to print without installing specific drivers on your phone.
