Re: Apparently ...
It's not only default settings, if you read the articles there are also serious flaws in the printer firmware implmentations. They have now OS-like functionalities but are not designed and implemented to be secure enough.
Frankly I prefer a "dumb" printer controlled by a remote print server running a real OS that gets regular Patches and have a full implementation of needed protocols, than a printer with a local embedded print server developed to be minimal and rarely updated.
I also wonder how many administrator routinely check and upgrade devices firmware.
