Production answer · sheet fit
What happens when a label template is larger than its sheet?
Preflight blocks the printer packet when the declared cut size cannot fit inside the declared paper after margins. The layout table shows the computed columns, rows, and per-sheet count.
Why this matters
The correction remains explicit: change paper, orientation, cut size, or margin, then inspect the proof again.
A reviewable sequence
- Check that dimensions use millimetres.
- Confirm portrait versus landscape.
- Include realistic device and finishing margins.
- Measure a 100% physical test after changing the setup.
