How to run this check

Open your print dialog only when ready. Inspect the printed page and record your observation.

Understand the result

PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.

What this cannot tell you

Browser printing cannot read ink levels, diagnose individual nozzles or confirm print output automatically.

If something seems wrong

Use the printer manufacturer’s own maintenance page for nozzle cleaning and alignment.

Good to know

Is anything uploaded?

Raw diagnostic input and media are processed locally. Results remain in this page’s memory until you download a report or leave. Hosting and Google Analytics requests still leave your browser. Analytics receives only broad test-usage categories, never these diagnostic contents. See the privacy policy.

Does a pass guarantee my hardware is healthy?

No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
