I set up my printer, worked well right away. I printed from my computer. The next day I could only print from my phone, not my laptop. I keep getting this message "Encryption Credentials Expired" The printer is working fine as it prints from my phone.

Ensure the latest firmware is installed and check for any change:
If that doesn't help, from System Preferences > Printers & Scanners, delete the printer and add it back by clicking the Plus sign.
Within the Use drop-down menu select the AirPrint option (rather than Secure AirPrint) and check for any difference.
