Product: HP LaserJet Pro MFP M428fdw
Operating System: macOS 26.0 Tahoe

My macOS just stopped printing to my HP. After going through some of the forums here, I found a resolution to create a self assigned certificate. However, every time I create a self assigned certificate, the time seems to be off by 3 hours. This certificate was created as 12:51 EST, but it shows as "Not Valid Before....3:51 PM". I have checked the printer time, uncheck the "sync" option. I have also reset the printer to factor options and tried, but no luck. My printer is basically rendered useless.

Adding a note. The printer always seems to create the certificate based on UTC time, irrespective of what the printer time is set to.
