Something that an unaided human can't read easily might run into
problems.
Why not use a font that's pleasant to read and include a checksum for
each line? The reduced character set should make errors reading the
checksums themselves less frequent and easier to detect. No OCR is
perfect so you may as well be prepared to deal with errors.
