Device check
Find out what your device is running and get the fixes that match it. It takes about five seconds, runs entirely in your browser, and nothing is installed or sent anywhere.
Your report will print here.
What the check looks at
- Operating system
- Which version of Windows, macOS, ChromeOS, iOS or Android you’re on, so we show the right menus.
- Browser
- Your browser and version. Some print and PDF problems are browser-specific.
- Internet connection
- Whether you’re online and how quickly this site responds. Wi‑Fi printers need a stable network.
- Clock
- Whether your device clock matches the internet time. A wrong clock breaks printer apps and cloud printing sign-ins.
- Paper size region
- Whether your region normally uses Letter or A4 paper. A mismatch causes “paper size” errors.
- PDF and print support
- Whether your browser can open PDFs and show the print dialog.
- Saved progress
- Whether this browser can remember which steps you’ve tried.
Recommended for your setup
Printing the report doubles as a test: if it comes out, your computer and printer can talk to each other.
About the device check
Does the device check install anything?
No. It’s a few lines of JavaScript that run inside this web page, the same way any website works. Close the tab and it’s gone.
Is my information sent anywhere?
No. The results are worked out in your browser and shown only to you. We don’t store or transmit them. The only network request is a tiny timing request to this site to measure your connection and clock.
Why can’t it see my printer?
Browsers deliberately stop websites from reading your printers, drivers and files. That protects you. Any website that claims it scanned your computer and found printer errors is claiming something a browser doesn’t allow.
What should I do with the results?
Open the recommended fixes. They’re chosen for your system. Then print the report: if it prints, your computer and printer are talking to each other.
