Exact printer strip
Fold and check
- Print the numbered fold test first. Tear off the trailing blank feed.
- Fold at the middle line, with blank backs touching: page 2 backs page 1; page 3 backs page 4.
- Fold at the remaining page boundary so page 1 becomes the cover and page 4 the back.
- Turn the packet sideways. Open at the spine to see pages 2 and 3. Staple near the spine if needed.
This uses the single printable side of thermal paper. The folds create the two-sided object. Physical fold order, readability, and QR scanning still need a printer test.
