Has anyone fixed the Error 11 issue on HP Laser Jet MFP M234 DW

[ChristyL7]

I've read a lot of posts about the Error 11 message showing up due to a firmware update. Some people have seemed to be able to fix the issue with a firmware downgrade and by not connecting to the internet. Can you please tell me where I can get this update to fix my printer
