I would ask your DD's teachers if they have trouble reading her handwriting. I regularly complain about DS' handwriting but apparently all his teachers can read it fine, as it hadn't ever affected his grades. With my DS, he writes very fast, which aftects legibility considerably. See if your DD's handwriting improves if she slows down. You may also want to check how many assignments are done on the computer, at least the final graded product. Fortunately, at our middle school, it is standard to submit typed work for longer writings so it is mostly an issue of the short assignments.
As far as reading, it may be easier to have your DD compare reading the same novel using different font sizes on a e-reader.
