Patch Lady – be aware of potential issues with HP firmware
Andrew warns
Hey @HP Color LaserJet Pro printer owners seeing a boot cycle with error 79 in the last few days. I think HP pushed bad firmware. I was able to resolve by turning off all networking to stop rebooting and then uploading old firmware via USB

in my case it was an MFP M281fdw, but I’m seeing a bunch of folks on HP’s forum with error 79 in just the last few days with different models. Symptom is constant reboot if wireless or wired networking is connected
Here’s a sample of the forum posts here: https://h30434.www3.hp.com/t5/Printing-Errors-or-Lights-Stuck-Print-Jobs/79-Service-Error-Boot-Loop/td-p/7842055
Remember once you get it working again to disable the remote firmware update until it’s known that it’s been corrected.
(Not all HP printer support over the internet firmware updates. But if yours is a newer model it probably does)
