Known issues.
- ▸Make sure you have the direct thermal “d” model — settings differ from thermal-transfer units.
- ▸If sizing is off, run media calibration so the ZD420d detects the label gap.
Zebra publishes macOS CUPS drivers, but JetLabel’s direct ZPL output is faster and avoids driver quirks for thermal sizes.
