Owner enters printer setup and qualification evidence. Supervisor investigates ordinary production-copy uncertainty. An Owner without Supervisor is limited to reconciling calibration copies. Operator can follow permitted signed-in test work. Source products retain their own authority for production printing and reprinting. See who can do what.
Setup and observed-output fields
| Field or control | What to enter | Checks and limits | If it is refused |
|---|---|---|---|
| Workstation name | A useful name for the actual computer | After trimming, non-blank and at most 80 printable characters. | Remove accidental control characters and identify the actual workstation; do not enrol a different computer to avoid an unresolved print. |
| Queue | The queue returned by the PrintStation app | Use the exact offered printer queue. Its retained name must be non-blank, printable and at most 255 UTF-8 bytes. | Check that the app found the intended printer. Do not abbreviate a real queue into a different name. |
| Media | The supported profile matching the loaded stock | Select the intended profile from the offered choices. Profile and printer qualification remain linked. | Load the correct stock or arrange the correct binding. Choosing a different profile solely to pass qualification is not valid evidence. |
| Printer model, Driver and version, Operating system | The actual device and software details | Each is non-blank and at most 120 characters after trimming. | Establish the real values. A convenient example value does not identify the device you qualified. |
| Print width for a ZPL binding | The printer's actual width in dots, when this field is offered | Whole number from 1 to 32,000. Leaving it empty uses the profile default. This field does not apply to a PDF profile. | Verify the device/profile rather than guessing a width or entering millimetres in a dots field. |
| Calibration measurements | The actual distance between the indicated reference-mark centres, in millimetres | The fields offer 0.01 mm steps; evidence is recorded to two decimal places and checked against that profile's displayed expected values and tolerance. | Recheck printer, stock, scale and measurement. Never enter the target value instead of the observed distance. |
| Scan the barcode into this field | The calibration barcode when the selected profile requests it | It must match that profile's exact expected scan. A profile without this requirement does not show the field. | Focus the scan field, check the actual copy and correct scanner or print problems before another qualification attempt. |
| Four calibration observation checkboxes | Actual observations of one copy, upright orientation, no clipping and no fit-to-page scaling | Every stated observation must be confirmed. Numeric measurements alone do not complete qualification. | Resolve the real physical problem or retain the failed result. Do not tick an unverified observation. |
| What did you find? | The supported observation for the exact copy/attempt | Unknown attempts offer observed output, no copy found, or still unknown. Submitted copies awaiting observation offer confirmation of observed output. | Use the form shown for this state. Not finding a copy does not prove none exists. |
| What you checked | Facts about the printer, queue, work area and any collected copy | Required non-blank note, at most 2,000 characters after trimming. No-copy-found also requires the duplicate-risk acknowledgement. | Record the actual investigation and retain unknown where necessary. A connection restart is not evidence of physical output. |
Qualification and investigation have different purposes
A calibration copy must be printed through the selected binding before qualification. Uncertain output blocks qualification until the appropriate person records the investigation. A successful later calibration does not resolve an earlier production attempt.
The tolerance and expected measurements belong to the selected profile. There is no single universal tolerance or target measurement to copy from another printer's guide. The optional calibration note is supporting context, not a substitute for required measurements, barcode and observations.
If output may already exist, use uncertain output and retain the job, copy, attempt and source-product references. A PrintStation observation does not authorise another source-product label or change its content. Qualification and destinations describe setup and route changes.
