How to set up Wi-Fi printing on an HP LaserJet Pro printer: from connection to troubleshooting

Wireless printing on printers HP LaserJet Pro While a laser printer saves time and eliminates cable clutter, many users encounter difficulties when first connecting. Unlike inkjet models, laser printers often require additional network configuration, especially if the router uses non-standard security protocols or dual-band operation. This article will help you understand how to connect correctly. printer to Wi-Fi, install drivers on various devices and troubleshoot common errors, from lack of connection to problems with device detection on the network.

We will look at the current models of the series LaserJet Pro (including M404n, M426fdw, MFP M227fdw and others), as their setup has common principles, but may differ in detail. We will pay special attention secure connection — how to avoid data leaks through open printer ports and why you shouldn't use the WPS protocol for connection. If your printer is already connected to the network but isn't printing, you'll find a diagnostic checklist at the end of the article.

1. Preparing the printer for Wi-Fi connection

Before setting up a wireless network, make sure the printer is HP LaserJet Pro ready to work:

• 🔌 Plug the printer into a power outlet and turn it on. Wait until it boots up completely (the lights will stop flashing).
• 📄 Check that there is paper in the tray - some models block network functions if there is no paper.
• 📡 Make sure your router is turned on and distributing Wi-Fi within range 2.4 GHz (most printers do not support 5 GHz).
• 🔐 Write down the network name (SSID) and password - you will need them for setup.

If the printer was previously used on a different network, reset the network settings. To do this:

1. Click the button Wireless (or Settings) on the printer panel.
2. Go to Network Settings → Wireless → Reset Wi-Fi Settings.
3. Confirm the reset (usually by holding the button) OK 3-5 seconds).

• ⏱️ The printer and router are close to each other (within a radius of 2 meters).

Instructions:

1. On the printer, press and hold the button Wi-Fi (or Wireless) 3 seconds until the indicator flashes.
2. Press the button within 2 minutes WPS on the router.
3. Wait for the indicator Wi-Fi on the printer will stop blinking (will become constantly lit).

⚠️ Note: Some models HP LaserJet Pro (For example, M404n) do not support WPS. If the indicator continues to blink for more than 5 minutes, use a different method.

2.2. Manual configuration via the printer panel

This method is universal and works on all models. You will need:

• 📝 The exact name of the network (SSID) and password.
• ⌨️ Ability to enter text on the printer screen (for models with a display).

Step-by-step instructions:

1. On the printer, press Settings (or Setup).
2. Select Network → Wireless Network → Wi-Fi Setup Wizard.
3. In the list of networks, find your Wi-Fi network and select it.
4. Enter your password using the arrow keys or touchscreen. For uppercase characters, use the Shift.
5. Confirm the connection. The printer will reboot.

2.3. Setup via the HP Smart app

Mobile application HP Smart (available for Android And iOS) automates the connection process and allows you to control the printer from your phone. Download it from the official store:

• 📱 HP Smart for Android
• 🍎 HP Smart for iOS

How to connect:

1. Turn on Bluetooth on your phone.
2. Launch HP Smart and select Add a printer.
3. Follow the on-screen instructions. The app will prompt you to hold your phone close to the printer for automatic detection.
4. Select your Wi-Fi network and enter the password.

The advantage of this method is that the application will automatically download the latest drivers and offer to update the printer firmware if necessary.

3. Installing drivers for Wi-Fi printing

After connecting your printer to the network, you need to install drivers for the devices you'll be printing from. Without them, the system won't be able to "see" the printer on the local network.

3.1. Installation on Windows 10/11

Modern versions of Windows usually automatically find and install drivers for HP LaserJet Pro, but sometimes manual adjustment is required:

1. Open Settings → Devices → Printers & Scanners.
2. Click Add a printer or scanner.
3. Wait for the system to find the printer on the network. If this does not happen, click The printer you need is not in the list.
4. Select Add a printer by TCP/IP address and enter the printer IP (you can find out by printing Network configuration page from the printer panel).
5. Specify the path to the drivers. If they are not on your PC, download them from official HP website, selecting the printer model.

⚠️ Important: If your printer appears as an "unrecognized device," remove it from the list and try installing it again, after downloading the drivers from the HP website. Using generic Windows drivers can cause printing errors.

3.2. Setup on macOS

On Mac the process is simpler:

1. Open System Preferences → Printers & Scanners.
2. Click + to add a new printer.
3. Select yours from the list HP LaserJet Pro (should appear in the section The nearest or by IP).
4. Select the driver. If it is not listed, click Other... and select HP in the list of manufacturers.

If the printer is not found, check that the protocol is enabled on the router. Bonjour (It is used to automatically detect devices on the local network).

3.3. Printing from Android/iOS

For printing from mobile devices:

• 📱 On Android: use the app HP Smart or the built-in print function (in the menu Share select Seal).
• 🍎 On iPhone/iPad: the printer must support AirPrint. Most models LaserJet Pro (since 2015) are compatible. Check the list at Apple website.

4. Solving common Wi-Fi printing problems

Even after a successful connection, errors may still occur. Here are the most common ones and how to fix them:

4.1. The printer does not connect to Wi-Fi

If the indicator Wi-Fi flashing or steady orange:

• 🔄 Restart your printer and router.
• 📡 Check if the printer's MAC address is blocked by the router's firewall (in the settings) MAC filtering).
• 🔐 Make sure your password is entered correctly (case sensitive!).
• 📶 Try temporarily disabling 5 GHz on the router - some printers do not support this range.

If nothing helps, reset the printer to factory settings (in the menu Reset settings) and try connecting again.

4.2. Documents do not print or get stuck

A common problem is that documents are sent to print, but nothing happens. Check:

• 🖨️ Print Queue: Open Control Panel → Devices and Printers, right-click on the printer and select View the print queueClear it if there are any stuck tasks.
• 🔄 Print service: in Windows, start services.msc, find Print Manager and restart it.
• 📄 Document format: some printers LaserJet Pro don't support printing PDF directly - try saving the file in .docx or print via HP Smart.

What to do if the printer prints blank sheets?

This could be due to several reasons:

1. The toner is out - check the cartridge level in the printer menu.

2. Incorrect driver settings - open the printer properties and make sure that the correct paper size is selected (not A3 instead of A4).

3. Paper jam — Even if you can’t see anything visually, open all the trays and check the sensors.

4. Firmware failure - update the printer software via HP Smart or web interface (enter the printer IP in the browser).

4.3. The printer periodically disconnects from the network

If the connection is broken:

• 📶 Check the Wi-Fi signal strength on your printer (print Network configuration page — look for the parameter Signal Strength). If less than 50%, move the printer closer to the router.
• ⚡ Disable the function on your router Energy saving for Wi-Fi (may disconnect when idle).
• 🔄 Set up a static IP for the printer in the router (in the section DHCP reservation).

If your printer HP LaserJet Pro MFP M227fdw or a similar model supports dual-band Wi-Fi, but it works unstable, force it to switch to 2.4 GHz in the network settings. To do this, select Network → Wireless → Advanced → Wi-Fi Band and mark only 2.4 GHz.

5. Additional settings for advanced users

If standard methods don't help, try these solutions:

5.1 Configuring ports and protocols

Sometimes the printer is not visible on the network due to blocked ports. By default HP LaserJet Pro uses:

• Port 9100 — for direct printing (RAW).
• Port 631 — for the record IPP (Internet Printing Protocol).
• Port 80 — for the web interface.

To open ports on your router:

1. Go to the router's web interface (usually 192.168.1.1).
2. Find the section Port Forwarding.
3. Add rules for the printer's IP address:

Protocol: TCP
External port: 9100
Inland port: 9100
IP address: [your printer's IP]

⚠️ Caution: Opening ports may reduce network security. After setup, verify that the printer's web interface (http://[IP printer]) is password protected (setting in the menu) Network → Security).

5.2 Using HP Web Jetadmin

To manage multiple printers HP use the utility on the network HP Web JetadminIt allows you to:

• 🖥️ Update firmware centrally.

1. Enter the printer's IP address into your browser (e.g. 192.168.1.100).
2. Go to the section Settings → Security → Administrator Password.
3. Set a complex password (at least 8 characters, with numbers and special characters).

6.2. Disabling unnecessary protocols

In the printer menu (Network → Protocols) disable:

• 🚫 Telnet — an outdated and insecure protocol.
• 🚫 FTP - if you do not use FTP printing.
• 🚫 SNMP - if network monitoring is not needed.

Leave only HTTP/HTTPS (for web interface) and IPP (for printing).

6.3. Configuring a firewall on a router

Restrict access to the printer from external networks:

• 🌍 In the router settings (Firewall → Rules) Block incoming connections to the printer's IP address from the Internet.
• 🔄 Allow access only for local devices (subnet 192.168.x.x).

It is also recommended to disable WPS on the router - this protocol is vulnerable to hacking.

7. Alternative printing methods without Wi-Fi

If you can't set up Wi-Fi, consider these options:

7.1. USB connection

Even wireless models HP LaserJet Pro support USB connection. To do this:

• 🔌 Connect the printer to the PC with a cable USB-A → USB-B (usually included in the kit).
• 🖥️ Install the drivers (Windows usually does this automatically).
• 📄 Print as if you had a local printer.

Cons: The printer will only be accessible from one PC.

7.2. Connecting via Ethernet

If the printer is equipped with a port RJ-45 (for example, models M426fdw or M477fdw), connect it to the router with a cable:

1. Insert the cable into the port LAN on the router and printer.
2. In the printer menu, select Network → Wired Network → Enable.
3. Set up an IP address (it’s better to assign it to the router).

It is more reliable than Wi-Fi and is suitable for offices with high print volumes.

7.3. Printing via cloud services
