Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

The 'Expired certificate - check the printer for errors' message on an HP Smart Tank 7300 series printer can be related to network and connectivity issues. To resolve these, you can try the following steps:

Step 1: Restart your devices

1. Turn off your printer and unplug the power cord.
2. Wait for 60 seconds.
3. Plug the power cord back into the printer and turn it on.
4. Restart your MacBook Air.

Step 2: Reset the printer network settings

For HP Smart Tank 7300 series printers:

1. Press and hold the "I" button on the printer control panel for 5 seconds until the buttons light up.
2. Then press and hold the Wireless and Cancel buttons simultaneously for 5 seconds until the Wi-Fi light blinks blue.
