## Handle uncertain output

1. **Open a run with uncertain output**

   Open a run with uncertain output.

   This synthetic run lost acknowledgement. A timeout does not prove that no label exists. Inspect the printer output before any retry or replacement.

2. **Open print history**

   Open print history.

   Use this history for the original run, linked reprints and uncertainty evidence. Keep submission, operator observation and physical confirmation separate.

3. **Review the configured printing route**

   Review the configured printing route.

   An office user qualifies the stock, dimensions, orientation and barcode before production. This prepared site routes to Assembly labels. Remote handhelds use the paired agent, with the printer managed in PrintStation.
