Commonly it is done with a pen or pencil.

Toilet paper do not count

I've used Optar. It works a lot better than just printing some QR codes. It fits 188 KiB on a sheet of letter sized paper after error correction. It does require a laser printer and a flat bed scanner though.

Maybe I won't use that to back up my photo library as few rough web searches suggests that the pile of paper would be something around 500 meters tall. Pretty neat technology and I suppose if you really need something stored you can etch that to stainless steel plate or something similar, but data density isn't the best around.

Storage is easy. Retrieval is more difficult. Test your backups.

This has to be a shitpost.

Transportation of paper-stored data

You can take the sheets with you, send them by post, or even attach them to homing pigeons
