Measure and check the printed values
Use example measurements, check both directions and practise comparing the complete printed values.
For operators
Use example measurements, check both directions and practise comparing the complete printed values.
Read these instructions on any device. Watch or practise a chapter on a desktop or laptop, with a desktop or mobile application layout. Demonstrations use sample data and simulated scanners.
Measure and check the printed values
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Stop scanner capture
Stop scanner capture.
The received values stay available for review. Stop capture before using other controls.
- 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.
- 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.
- 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.
- Stop scanner capture
Stop scanner capture.
The received values stay available for review. Stop capture before using other controls.
- Review the report
Review the report.
Review the evidence before sharing it. By default, device names, notes and received text are excluded.
- 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.
