The best practices for paper wallets IMO would be:
1. Put the paper in a fireproof safe if your bitcoins are worth enough for them to be protected (this can also be helpful for dumping the airgapped laptop also so no one tries to check their social media through it)...
2. Air gapped computers are extremely secure on their own (with a password) and are probably better than a paper wallet. But if you're wanting to use a paper wallet (i.e to not put all your eggs in one basket) then air gapping the computer and the printer is the best option.
If you can avoid printing entirely, then try writing out the address or using a QR code (you should encrypt the information you are printing anyway).
A better alternative to writing down your key or printing it off is to use some software like electrum which generates seeds for you to use and these are 12-24 words depending on the security you are after and are much easier to write down and store as you don't have to question "if that's a 5 or an S?".
3. Try finding a way to verify that what you have downloaded to make a seed has given you an accurate address and private keys by putting it into two devices not connected to the internet (or the same device with different operating systems).

Some alternatives to paper wallets:
1. Buy a cheap android phone/tablet for a maximum of $100 (preferably an old one that's still sold) and install electrum on it. Then take it completely offline and put it in a safe and secure place.
2. If you can go a bit higher, you can buy a phone and a trezor (or another hardware wallet) and try using that to store your funds (or use the hardware with a computer instead of a phone, this can also be done in an airgapped way once all firmware is installed).
