[Discuss] printer issue

[Ben Kallus]

It's worth noting the security risks that come with network printers.
Their firmwares is not often updated, and has been shown to be
insecure time and time again.^1 You may be better off connecting it to
a computer you trust, then exposing it as a network printer through
that computer. The photosmart D110 is the printer I had as a kid, and
I don't think it's gotten an update in a very long time.
