Multifunctional device HP LaserJet Pro 400 MFP M4720 It remains a reliable assistant in many offices, providing high-quality printing and scanning. However, switching to remote work or upgrading an office network often requires users to connect this device to Wi-Fi, bypassing the trusty LAN cable. Setting up a wireless connection on this model has its own nuances that must be taken into account for the stable operation of the entire document management system.
Unlike modern models with touch screens, the interface HP 4720 The printer is based on a monochrome display and navigation buttons, requiring a clear understanding of the steps. Incorrect IP address configuration or security protocol selection can result in the printer becoming "lost" on the network, making computers unable to see it. In this article, we'll cover all connection steps in detail, from preparing the equipment to installing drivers on various operating systems.
Before you begin manipulating the menu, make sure your wireless router is working properly and is providing an internet signal within the printer's line of sight. It is critically important to know the exact name of your network (SSID) and its password., as entering this information will be required during the setup process. It's also recommended to temporarily disable security macros on your router if they're blocking new devices, although this is rarely necessary for basic connections.
Equipment preparation and compatibility testing
The first step is to physically prepare the device for wireless operation. Make sure the MFP is plugged into a power outlet and ready. If an Ethernet cable is connected to the back of the device, it must be disconnected, as simultaneous operation of both wired and wireless interfaces on this model is typically not supported or requires manual prioritization.
Next, you should check the frequency compatibility. Model HP M4720 The printer operates in the 2.4 GHz band, which was the standard for office equipment of the time. If your router only broadcasts in the 5 GHz band, the printer simply won't see it. Modern dual-band routers often have the "Smart Connect" feature enabled, which combines networks, sometimes causing conflicts. In such cases, it's best to temporarily separate the networks in the router settings.
⚠️ Important: Make sure you know the encryption type of your Wi-Fi network. HP 4720 Supports WPA2 and WPA standards, but may not work correctly with the latest WPA3 or corporate 802.1x protocols without additional configuration of Radius servers.
For successful synchronization, you'll also need a computer or laptop connected to the same Wi-Fi network you plan to connect the printer to. This is necessary for software installation and initial IP address configuration. If you don't have access to a Wi-Fi connection, you can configure the printer via a USB cable, but wireless setup is preferred for flexibility.
☑️ Ready to connect
Setting up a wireless network through the control panel
Basic configuration is performed directly through the MFP's control panel. This is the most reliable method, requiring no drivers on the computer. First, press the wireless button on the front panel of the device. If the indicator light is green, the wireless module is active, but not necessarily connected.
Using the navigation arrows, navigate to the network settings menu. You need to find the item Wireless Setup Wizard (Wireless Setup Wizard). This tool will automatically scan the air and display a list of available networks. Find your router's name (SSID) in the list and click OK to select it.
The system will prompt you to enter a password. Use the on-screen keyboard or the navigation buttons to enter characters. Be careful with letter case, as the password is case-sensitive. After entering, confirm the action, and the printer will attempt to establish a connection. A successful connection will be confirmed by the wireless indicator lighting up and a configuration report being printed, if this option is enabled.
- 📶 Search network: The device scans the air for 10-20 seconds.
- 🔑 Enter key: An accurate entry of the WPA/WPA2 security key is required.
- ✅ Confirmation: The Wi-Fi indicator lights up with a steady green light.
- 📄 Report: The printer can automatically print a page with the current IP address.
If the connection doesn't work the first time, don't panic. Often, the problem lies in an incorrect password or a weak signal. Try moving the printer closer to the router for the initial setup, then returning it. It's also worth checking that the MAC address list in the router settings isn't full if you have an access filter enabled.
What to do if the printer does not see the network?
If your router isn't listed in the network list, it may be hidden (Hidden SSID). In this case, select the option to manually enter the network name in the Wireless Setup Wizard menu. Also, check if AP client isolation is enabled on your router, which prevents devices from communicating within the network.
Use Wi-Fi Direct technology for fast printing
Function Wi-Fi Direct Allows you to connect mobile devices or laptops directly to the printer, without a router. This is ideal for situations where you need to quickly print a document from your phone while traveling for business or in an area with limited network access.
To activate the mode on the control panel HP M4720 go to the wireless settings menu and select Wi-Fi DirectSet this to "On." The device will create its own access point. The printer screen will display the network name (usually beginning with "DIRECT-HP") and the connection password.
On your smartphone or tablet, open the Wi-Fi settings, find the printer's network, and connect by entering the password. You can then print documents through the app. HP Smart or the standard printing interface of the operating system. In this mode, the printer may not have access to the Internet, so the E-Print cloud printing functions will not work.
| Parameter | Description | Default value |
|---|---|---|
| Network name (SSID) | DIRECT-HP LaserJet Pro 400 MFP M4720 | It can be changed |
| Password | Random character set | 12345678 (often) |
| Max clients | Number of connected devices | Up to 5 devices |
| Protocol | Connection type | 802.11 b/g/n |
Using a direct connection is especially convenient when the main corporate network is overloaded or has strict security policies that prevent the connection of peripherals. However, for regular office work, it's better to use a router connection to ensure simultaneous printer access for all network employees.
Installing drivers and software
Once the printer is successfully connected to the network, you need to configure your computer to work with it. Windows or macOS can automatically detect the network printer, but for full functionality, including scanning and tray management, you need to install the full driver package.
Go to the official support website HP and enter your device model. Download the package HP LaserJet Pro 400 MFP M4720 Full Feature Software and DriverRun the installer and select the connection type "Wireless" or "Network." The program will automatically find the device on the network by IP address.
During the installation process, you may be asked to confirm the device's use on the network. If the automatic search fails, select the "My printer isn't listed" option and enter the IP address manually. You may have seen this address in the network configuration report that the printer printed after connecting, or you can find it in the device menu under "Report" -> "Configuration."
