# NameLand: reconstructing Casio KL-A45 serial printing

> NameLand reconstructs serial printing for the Casio KL-A45 label printer from communication observed between the device and Casio's Windows XP software. Its Python program sends arbitrary text as QR codes through a USB-to-serial cable with a 2.5 mm TRS connection. The README describes the cable wiring and notes that other printer models may need code changes.
