Use example measurements, check both directions and practise comparing the complete printed values.

## Measure and check the printed values

1. **Choose the example printer resolution**

   Choose the example printer resolution.

   Use the resolution of the printer for a real check. This example uses 203 DPI. If you do not know, keep the unknown option.

2. **Prepare the known test sheet**

   Prepare the known test sheet.

   The original PDF is checked and its preview is rendered from the same bytes. Downloading a sheet does not mean a label has printed.

3. **Record the example print observation**

   Record the example print observation.

   For practice, record that our example label is available. In a real check, choose this only after you have the paper label.

4. **Confirm the printed test-sheet code**

   Confirm the printed test-sheet code.

   Check the code and version printed on the sheet. All the test sheets share the same barcode values, so a matching scan cannot identify the sheet.

5. **Record the example width measurement**

   Record the example width measurement.

   Enter 50.05 millimetres for this practice example. On a real label, measure between the tick centres on paper, not on the screen.

6. **Record the example height measurement**

   Record the example height measurement.

   The two directions are checked separately. These example values are within the chosen tolerance; this does not qualify a physical printer.

7. **Start the scanner field**

   Start the scanner field.

   The scan box is ready. Scans go only to the focused box. The practice inputs here are simulated.

8. **Scan the complete example value**

   Scan the complete example value.

   Every character matches the selected expected value, including the zeroes. A text match alone does not prove print quality or optical scanning.

9. **Stop scanner capture**

   Stop scanner capture.

   The received values stay available for review. Stop capture before using other controls.

10. **Choose the QR test value**

   Choose the QR test value.

   Choose the value of the code you are testing. A QR code needs a scanner that can read it; manual text entry only checks equality.

11. **Start the scanner field**

   Start the scanner field.

   The scan box is ready. Scans go only to the focused box. The practice inputs here are simulated.

12. **Enter the known QR test value**

   Enter the known QR test value.

   The selected QR value matches exactly. This practice input does not test a real QR scanner.

13. **Stop scanner capture**

   Stop scanner capture.

   The received values stay available for review. Stop capture before using other controls.

14. **Review the report**

   Review the report.

   Review the evidence before sharing it. By default, device names, notes and received text are excluded.

15. **Download the reviewed JSON report**

   Download the reviewed JSON report.

   The real exporter offers the reviewed report for download. Keep it with your setup evidence; the browser does not confirm where you saved it.

Use real paper measurements and keep useful evidence. This training does not qualify physical equipment.
