What really matters is WHERE you're generating the paper wallet (so you need a trusted air gapped PC) and how you're printing this information (does your print save a history of what you print?, are you using a trusted address generator?). These are the main things you should focus.
That is what I mean. Can I just buy an old PC and use it as an air-gap? Or should DIY one? How do I know what printer saves my print jobs vs. one that doesn't? Are there recommended products? Protocols? What is the preferred "set up?"
