How to Lock HP Printer Settings & Secure Your Printer

This guide shows you how to lock HP printer settings using the printer’s built-in control panel and embedded web server (EWS), so that only you or authorized users can change network, security, or administrative options. You’ll also learn how to set a printer admin password, disable unneeded services, and protect against unauthorized access from the network. No special tools are needed—just your printer’s IP address and a web browser.

What You’ll Need

• An HP printer connected to your network (Wi-Fi or Ethernet).
• A computer or smartphone on the same network.
• The printer’s IP address (found on the printer’s control panel or a network configuration page).
• Administrator access to the printer’s settings (usually the default admin password is blank, but you’ll set one).

Step-by-Step

1. Find the printer’s IP address. On the printer’s control panel, go to Setup (or the gear icon) > Network > Network Summary or Wi-Fi Status. Write down the IPv4 address (e.g., 192.168.1.20). Alternatively, print a network configuration page from the control panel.
2. Open the embedded web server (EWS). Open a web browser on your computer and type the printer’s IP address into the address bar. Press Enter. The HP EWS page loads—this is the main interface for managing printer settings.
3. Set an administrator password. In the EWS, click the Security tab (or General > Security). Look for Administrator Settings or Set/Change Password. Enter a new password, confirm it, and save. This password will be required to access the EWS and change any settings.
4. Lock the control panel (if supported). On the printer’s control panel, go to Setup > Preferences > Security (or Lock Settings). Choose Lock and set a PIN. This prevents physical changes to settings without the PIN. Note: Not all models have this feature; if you don’t see it, skip to step 5.
5. Disable unneeded network services. In the EWS, go to the Network tab > Network Settings. Look for services like Web Services, Bonjour, IPP, or FTP. If you don’t use them, turn them off to reduce attack surface. Be careful: disabling some services may affect printing from mobile devices.
6. Restrict access to the EWS. In the EWS, go to Security > Access Control. You can set the EWS to be accessible only from a specific IP range (e.g., your local subnet). Enter your network’s IP range (e.g., 192.168.1.0 to 192.168.1.255) and save.
7. Set a firmware update schedule. In the EWS, go to General > Firmware Update. Choose to check for updates automatically or manually. Keeping firmware current patches security vulnerabilities.
8. Enable secure printing (if available). If your printer supports it, go to Security > Secure Printing or PIN Printing. This requires users to enter a PIN at the printer to release their print jobs, preventing sensitive documents from sitting in the output tray.
9. Disable remote management (if you don’t need it). Some HP printers allow remote management via HP Smart or cloud services. In the EWS, go to Web Services and disable if you don’t use HP ePrint or cloud printing.
10. Log out and test. After making changes, log out of the EWS. Try to access the EWS again—it should ask for the admin password. Also test printing to ensure the printer still works.

Common Mistakes

• Using the default password: Many HP printers ship with an empty admin password. Leaving it blank means anyone on your network can change settings.
• Locking the control panel but not the EWS: A PIN on the panel doesn’t stop someone from accessing the EWS via the network.
• Disabling too many services: Turning off all network services might break printing from your phone or cloud printing. Disable only what you don’t use.
• Not writing down the password: If you forget the admin password, you may need to reset the printer to factory defaults, which wipes all settings.
• Using a weak password: A short or common password is easily guessed. Use a mix of letters, numbers, and symbols.

Tips

• Use a password manager to store the printer’s admin password.
• If your printer is used in a shared office, assign a designated person to manage the settings.
• Regularly check for firmware updates—HP releases security patches periodically.
• If your printer supports it, enable HTTPS on the EWS to encrypt the connection (look for Network > Security > HTTPS).
• Consider placing the printer on a separate VLAN if your network supports it, to isolate it from other devices.

Troubleshooting

• Can’t access the EWS: Make sure your computer is on the same network as the printer. Try pinging the printer’s IP address. If that fails, check the printer’s network connection and restart it.
• Forgot the admin password: You’ll need to reset the printer to factory defaults. On the printer’s control panel, go to Setup > Restore > Restore Factory Defaults. This clears all settings, including the password.
• Printer not responding after changes: If you disabled a service that the printer needs (like IPP), printing may fail. Re-enable the service via the EWS or reset the printer to defaults.
• EWS shows a security warning: If you see a certificate error, it means the printer’s self-signed certificate isn’t trusted. This is normal for a local device. You can proceed, or install the printer’s certificate if you want to remove the warning.
• Control panel lock not working: Some models only lock the setup menu, not printing. Check your printer’s manual to see what the lock actually protects.

Frequently Asked Questions

What is the default admin password for HP printers?

Most HP printers have no default admin password—the field is blank. You should set one during initial setup or as soon as you access the EWS.

Can I lock the printer so only certain people can print?

Yes, if your printer supports PIN printing or user authentication. You can set up PIN codes for users in the EWS under Security > User Access or Secure Printing.

Will locking settings affect normal printing?

No, locking admin settings only prevents changes to configuration. Printing should work normally unless you disable a service that your devices use.

How do I reset the admin password if I forget it?

You’ll need to restore the printer to factory defaults. This wipes all settings, including network configuration, so you’ll need to reconnect it to Wi-Fi afterward.

Is the embedded web server the same as HP Smart?

No. The EWS is a web page hosted by the printer itself; HP Smart is a separate app that connects to the printer. The EWS gives you deeper control over security settings.

Can I lock the printer’s control panel without a PIN?

Some models allow you to disable the control panel entirely via the EWS, but most require a PIN to lock it. If your model doesn’t have a lock feature, you can physically cover the panel or place the printer in a secure area.
