Isn't that why we type up a note or document and print it out?
If you want guranteed consistent legibility, typing it up after you write it down would be superior.
You'd love to think so but still common in the accountancy world for there to be a lot of hand written bits, particularly from older school managers and partners who prefer a physical set of accounts to review and so make their notes on them, or even use a tablet with a handwriting app rather than type up on a keyboard.
This will die out sooner than later though as these people retire so you are right that, in theory, that will be the process.
