Product: HP Color LaserJet Pro 4202
Operating System: iOS

Hi,

The printer was initially set up to print wirelessly and worked great from both Android & iOS (and Windows).

After a firmware update about a month ago, printing from iOS generates an error “[Printer] The security of the connection could not be verified”. The message repeatedly prompts until I restart the device (and nothing is printed). There is a slightly different error on an older version of iOS, but the context is the same and you can’t print.

On Android, you can still print, but it’s glitchy with 2 printers sometimes listed.

 

Clearly it’s a security / cert issue somewhere. I’ve reset the printer from the device, rejoined WiFi but experience the same issue.

I’ve found the advanced settings portal and tried a few things with no success, but don’t want to delete any of the certs as I’m not sure I can recreate one of them.

 

Any suggestions?

TIA.
