Thank you for sharing! I would like to get deeper: how many Bytes is possible to write on a paper with this or that encoding, how about having some extra bits for the sake of data loss recovery, what are approaches to a multi-page storages and are there any patches for incremental archiving? I will try to remove dust from my A4 scanner and try to read that MP3 from printed medium, seems a bit insane to store multimedia in a paper but who needs to store it without proven ability to read. My printers love to mess with ink (especially ones with pirate-refilled cartridge) so I do not really believe this is practically at maximum resolution.
