That's why I keep it simple. I run things out of a closet with an air gaped computer, a single printer, and a gun...in case the printer starts acting suspicious.
These days that is a very real possibility if you run Windows.
You've already lost, then. Printers' output can be uniquely identified.
Nothing should ever be in dead-tree format. If you need to carry something that does not need electricity to display text, use eInk. Or build your own printer.
