We can add a mode for people to write down the codewords but given that a mistake when copying them can lead to the shard becoming unusable I suspect it shouldn't be the default. Not to mention that you want to make sure the ink won't fade at a different rate to the printed ink and possible legibility issues.
With printers these days you never know what they store or where the documents they print go. Thus it would be insecure to print the whole shard-pdf (or, at least all shards) on a printer as the shard content could be recovered from it. Since there is already a shard password, it would make sense to not print it by default and have the user write it down manually. While this requires quite a bit of manual labor it is the only way I could figure out how to print the shards securely when designing a similar system.
