What is a crypto paper wallet?

So, could you please explain what exactly a crypto paper wallet is? I've heard the term before, but I'm not entirely clear on its purpose and functionality within the world of cryptocurrency. I'm curious to know if it's a secure way to store my digital assets, and how it differs from other types of wallets. Also, is there a specific process involved in setting up a paper wallet, and what kind of precautions should I take to ensure its safety?
