Quick answer
Check that the setup device is on the intended home Wi-Fi, then use HP app to add the printer with the correct new-versus-existing device option. Allow the legitimate discovery permissions required by your platform. HP’s 8120/8130 support pages currently flag firmware for network-connectivity fixes; if the printer remains unreachable wirelessly, its documented update process can use a temporary USB connection from a computer. Do not interrupt an update or use firmware for a similar-looking model.
Choose the check that matches your symptom
Start with the row that describes what you see. You do not need to try every step.
| What you notice | Where to start |
|---|---|
| Printer missing during initial setup | Check discovery and the correct Add a device flow |
| 8120/8130 repeatedly loses Wi-Fi | Review the model-specific firmware advisory |
| Connected printer has a stuck Windows job | Use queue checks |
Before you start
- Use the exact model and platform described below. If a label or connection differs, stop and identify it before changing settings.
- Keep passwords, verification codes, serial numbers and private documents out of any help request. Use synthetic or redacted details when describing an error.
Why this happens
A printer absent from the setup app may have a discovery, network or firmware problem rather than broken hardware. HP app replaces HP Smart on supported platforms, so older instructions can show different controls. Setup mode, a previously installed device and an actual internet-service outage need different responses.
What to do, step by step
Try one step at a time. Stop when the issue is resolved. If an instruction doesn't match your device, use the official model-specific guidance instead.
Confirm the model, network and app version
- Read the exact printer model including any e suffix. Keep its regional identity and private serial number available for your own support lookup, without posting them in chat.
- Connect the computer or phone to the intended secure home Wi-Fi and place it near the router and printer. Avoid an isolated guest network.
- Use the current official HP app offered for that model and operating system. HP Smart remains available where HP app is not supported; do not install a third-party driver bundle.
Prepare legitimate discovery permissions
- Turn on Bluetooth on the setup device so HP app can discover the printer as documented. This does not mean print jobs will use Bluetooth.
- On a phone, allow the relevant local discovery/location permission when the genuine HP app requests it. Review the app identity and permission rather than accepting unrelated prompts.
- For the guided Wi-Fi setup, HP recommends a Wi-Fi connection on the computer rather than a temporary Ethernet connection. Preserve workplace network requirements and ask the administrator if applicable.
Choose the correct new or existing printer flow
- Open HP app and use the plus sign to Add a device.
- Choose Set Up a New Printer for a printer not previously set up on this device, or Choose an available printer for an already used printer.
- Select your exact printer and follow its prompts. If it is not found, use the exact model’s documented Wi-Fi setup-mode restoration; HP says to add it within two hours after restoring that mode. Do not use an unrelated model’s reset-button combination.
View larger Review HP’s 8120/8130 firmware advisory if needed
- If wireless connection continues to fail, review the firmware offered for your exact printer on HP’s own Software and Driver Downloads page. HP currently identifies updates for network-connectivity issues in this family.
- On Windows, HP’s advisory permits connecting the powered printer temporarily by a suitable USB data cable if network access fails. Choose Firmware for the correct model and follow its update program.
- In HP Printer Update, a Ready status permits choosing your own printer and Update. If the printer does not appear over the network, the advisory says to connect USB, wait about 20 seconds and use Refresh. If it says Up-to-Date, do not force an older version.
View larger Confirm network printing and avoid unnecessary replacement
- After any completed update or corrected setup, reopen the app and confirm the printer on the intended network. Try one short test page.
- If the printer connects but Windows reports offline or a job is stuck, use the separate queue guide instead of repeating initial setup.
- If it still fails, give HP the model, app/OS version, exact message, discovery result and update status. Do not purchase a replacement solely because the app could not discover it once.
Still not working? Know when to stop
Stop before firmware work on unstable power, an uncertain model or a restricted workplace device. Never interrupt a running update, downgrade firmware from an untrusted source or reset the whole router for one missing printer.
Write down the exact model and error message before contacting official support.

- Up to 11 × 17-inch document handling and two 250-sheet trays.
- Single-pass two-sided scanning and a larger color touchscreen.
Consider only when: You need wide-format documents or a confirmed replacement; a Wi-Fi discovery problem alone does not justify it.
Check compatibility: Verify the exact US C2WH0A model, desk space, supported software and its own ink requirements. Any Instant Ink trial is optional and becomes a paid subscription unless cancelled under its terms; do not count a trial as free lifetime supplies.

HP Color LaserJet Pro MFP 4301fdw
A color-laser office alternative when frequent documents and a different print technology warrant replacing the 8120.
- Color laser print/scan/copy/fax with automatic two-sided printing.
- Document feeder, wired Ethernet and wireless networking for a small office.
Consider only when: Those workgroup functions or a diagnosed hardware fault justify the investment after the free connection checks.
Check compatibility: Budget for its own toner and check supported computer/mobile printing. HP dynamic security restricts cartridges with non-HP chips/circuitry; starter cartridges are not full high-yield replacements. A new printer does not fix router isolation or an incorrect password.

Frequently asked questions
Is HP app the same as HP Smart?
HP says HP app replaces HP Smart where available. The supported application and controls depend on the platform.
Why does setup ask for Bluetooth or location?
HP documents them for discovery during setup on relevant platforms. Review prompts from the genuine app; this does not turn Bluetooth into the print connection.
Can I update without working Wi-Fi?
HP’s Windows advisory documents a temporary USB connection for the update. Verify the exact model and use a suitable data cable, stable power and HP’s own update program.
Do I need Instant Ink to fix Wi-Fi?
A supplies subscription does not fix discovery or network configuration. HP+/Instant Ink customers have separate account requirements, which should be reviewed before enrollment.
