If you’re receiving a warning on your Mac that says “Printer encryption credentials have expired”, don’t worry, there are solutions available. Dealing with this error can be frustrating, especially when you rely on your printer for work. However, with a few simple steps, you can navigate this problem and get your printer back up and running. Let’s explore what this error means and how to fix it.

What Does Encryption Credentials Have Expired Mean on a Printer?

This error indicates that your device needs credentials from the printer, but believes that they are expired or out of date. These credentials contribute to security, specifically the Secure Internet Printing Protocol. While this issue often occurs after updating macOS, there can be other causes as well. The good news is that there are simple solutions available.

How Do I Fix Expired Encryption Credentials?

There are several methods you can try to resolve this issue. The easiest approach is to remove the printer from your Mac and then reconnect it. This simple step often does the trick. If that doesn’t work, you can consider the following alternatives:

Reinstall the Printer Via AirPrint Protocol

One of the fastest ways to fix the “Encryption Credentials have expired” error is to reinstall the printer. This error typically occurs when an AirPrint driver is installed and set as Secure AirPrint. However, after a certain period of time, the printer drivers expire, rendering the printer unusable. Reinstalling the printer should resolve this issue.

Use LPD Protocol to Reinstall Printer

For those using an older printer or not achieving desired results with AirPrint, using the LPD protocol may be a suitable solution. Follow these steps:

  • Go to System Preferences/System Settings.
  • Select Printers and Scanners.
  • Choose the Plus Sign to add a printer.
  • Click the IP tab and select LPD, or Line Printer Daemon from the Protocol list.
  • Give your printer a name, enter its IP address, and then select Add.

Reset Printer Network Settings

If you are still experiencing problems, you may need to reset your printer’s network settings. Please note that this method is mainly effective with newer printers, and the instructions may vary for different printer models. Follow these steps:

  • Unplug your router and keep it turned off.
  • Restart your printer.
  • From your printer’s control panel, go to Setup.
  • Under Network Setup, choose Restore Network Settings.
  • Power off your printer and wait for about 30 seconds before plugging the router back in.
  • Once your network is restored, turn on your printer.
  • Launch the Wireless Setup Wizard for your printer.

Make a New Self-Signed Certificate

If your printer allows you to manage settings and install updates through a webpage, you may be able to create a new self-signed certificate. Follow these steps:

  • Enter your printer’s IP address in a web browser. You can find the IP address by going to System Settings/Preferences > Printers and Scanners > [Your Printer]. It will be under Location. Alternatively, you can directly view the IP address from the printer’s UI if it has a screen.
  • Select the Network option.
  • Choose Advanced Settings and then click the Plus Sign.
  • Select Certificates and then click Configure.
  • Tap Create a New Self-Signed Certificate.
  • Choose Finish.
