I don't think humans should be doing the text entry, too much room for human error.

But of computers enter the text and then the printing is still done by cast metal, you could have an interesting business.

I am sure that will be more expensive, but will people be willing to pay a premium?

Humans did fine with tippex and typewriters years ago. The delete key is a modern luxury. People were much better at typing accurately back then.
