I recently found an unopened HP PhotoSmart 6520 in my mother in law's closet. She had it prepared for when her workhorse gave out. I've needed a scanner downstairs and want to figure out if I can safely connect this thing to the network without it bricking itself. You all probably already know HPs reputation and how they do sketchy things like blocking third party ink with firmware updates after the consumer has already purchased the product, or making it so you can't scan if the ink is out. Right now, all I want to do is scan some docs to linux, likely over USB, maybe over the network if I can get it to work. I don't want to rule out that my partner may want to print something.

What is the best way to go about this? Can I block the printer from accessing the internet on my router, but still have devices on the local network print to it? Should I? Can I see somewhere if updates are reported as safe and only then unblock the internet access so it can update?

Problem is, as usual, Google is less than helpful. Does anyone know where I can find a list of which printers were affected and which are still affected?
