If you have a lot of data that you're printing, choose a font that's easy to OCR, or consider using a 2D or 1D-stacked barcode symbology like QR Code or PDF417.

If you have a lot of data that you're printing, choose a font that's easy to OCR, or consider using a 2D or 1D-stacked barcode symbology like QR Code or PDF417. PDF417, in particular, can be encoded with up to 50% redundancy and uses an open standard, plus its stacked nature makes it easy to scan with 1D and 2D scanners. It's likely to remain supported in a variety of devices for the foreseeable future. https://en.wikipedia.org/wiki/PDF417 https://en.wikipedia.org/wiki/PDF417 Information density is much higher with barcode than it is with simple text printed on paper, although you'll need a lot of time and some pretty sharp eyes to decode them without electronics.
