Summary

The text discusses the challenges and solutions for printing and OCR (Optical Character Recognition) of digital data, specifically focusing on encoding schemes like hexadecimal, BIP39, and base64. It highlights the difficulty in achieving 100% character recognition accuracy due to the similarity of certain characters, which complicates the OCR process. The author shares successful setups for OCRing hexadecimal and BIP39 data, achieving full accuracy using specific fonts, scanning resolutions, and OCR engines. For base64, a post-correction method involving checksums is proposed to repair common OCR errors. The text also explores the potential of tailored encodings and optimal fonts to improve OCR performance for various data formats.
