Why do you ask about a "scenario you fear"? I don't "fear" anything. It is simply a fact that printers have an update mechanism that doesn't require the printer to have access to the internet, which is merely a print job. And so if one wants, as the gggp comment did, to ensure that ones printer cannot be updated without ones deliberate instigation, one must also be aware of all possible sources of print jobs. I don't know why you seem to have a problem with this. What scenario do you fear? In what way does this knowledge hurt you?
