Although it's a good experience to generate and print a paper wallet securely, you need to have technical knowledge to do so, as well as at least one offline device to generate the private key. Optionally, you can protect the private key by encrypting it with BIP-38.

However, due to the ease of BIP-39, I honestly don't see any more reasons for a paper wallet with a single private key. If I were to generate an offline wallet today, I'd have a few options such as:

1 - Use an offline computer to generate a BIP-39 wallet or electrum seed, I'd use this initial BIP-39 seed as a master seed and derive a new child seed through BIP-85 using a passphrase. I'd write down both backups on paper and also keep encrypted backups of the derived wallet saved:

2 - Using the master seed, I could create as many wallets as I want, using passphrases for different purposes, the same goes if I want to divide amounts in a paper wallet (which can also be generated via BIP-85).

3 - Hardware wallets: HWs (mainly open source and air-gapped) combine the best of both worlds: the security of a paper wallet and the convenience and ease of a software wallet.

I intend to open a topic soon to address these questions in more detail.
