You hit print on an invoice or a boarding pass, and instead of paper coming out, your HP OfficeJet Pro 9015e just sits there marked "offline." The lights look normal, the printer seems awake, yet your computer or phone insists it cannot reach it. The good news is that this is almost always a dropped connection or a stuck setting, not a hardware failure, and the OfficeJet Pro 9015e is a full wireless all-in-one with the exact network paths you need to bring it back. Work through the fixes below in order, starting with the quickest and safest, and stop as soon as your printer comes back online.
Start With a Clean Power Cycle on the Same Network
Most "offline" errors are simply a dropped connection between the printer and the device sending the job. HP's first move is the simplest one, and it clears the largest share of these errors before you touch any deeper settings.
- 1.Turn off your printer and disconnect it from the power supply.
- 2.Restart the device you want to print from and your internet router.
- 3.Turn the printer back on and try to print again.
Before you retry, confirm that the printer and the device you print from are on the same network. The 9015e is dual-band (compatible with 2.4 GHz and 5.0 GHz operations), so if your router splits those bands into separate names, make sure the printer and your computer or phone are joined to the same band and SSID. A printer on 5.0 GHz and a laptop on 2.4 GHz can look "offline" simply because they are on different networks.
Let HP's Diagnose & Fix Tool Do the Heavy Lifting
Diagnose & Fix in the HP app is HP's official automated troubleshooter, and it is the single most efficient step here. It checks whether the printer is offline, works to reconnect it to your network, and resolves common print problems automatically, so it is worth running before you move on to manual steps.
- 1.Open the HP app and click your printer.
- 2.Click Diagnose & Fix (on Windows it is the wrench icon in the bottom-left corner; on macOS choose Diagnose & Fix from the Printers menu).
- 3.Click Start and wait for the analysis to complete. Do not close the HP app while it runs.
If you are on an older operating system where the HP app is not available, HP Smart still provides full-feature support and gets you to the same place.
Clear the "Use Printer Offline" Setting in Windows
On Windows, the printer can be flagged offline by a setting rather than by an actual connection problem. If "Use Printer Offline" or "Pause Printing" is switched on, jobs stack up and nothing prints, even when the network is perfectly fine.
- 1.Open Control Panel and click "View devices and printers".
- 2.Right-click your HP OfficeJet Pro 9015e and click "See what's printing".
- 3.In the print queue window, make sure "Pause Printing" and "Use Printer Offline" are NOT selected.
- 4.If a checkmark displays next to either item, select the item to clear the checkmark, then try to print.
While you are here, set the 9015e as your default printer so jobs are not silently routed to a different device. If printing works after clearing the checkmark, the printer is online again.
Flush a Jammed Print Queue
A single stuck document can freeze the whole queue and keep the printer showing offline until the jam is cleared. The Diagnose & Fix tool handles this for you in many cases, so running it (Fix 2) often resolves this on its own.
If you prefer to do it by hand, you can cancel all documents in the Windows print queue. On macOS, deleting a stuck job from Printers & Scanners and then reopening the queue often restores normal printing.
Reconnect to Wi-Fi After a Router or Network Change
If you recently changed routers, renamed your network, or updated your Wi-Fi password, the printer loses the credentials it was using and drops offline. The Wireless Setup Wizard on the printer walks it back onto your network.
- 1.Place the printer near the router to ensure a strong signal during setup.
- 2.From the printer's Setup, Network, or Wireless settings menu, select "Wireless Setup Wizard".
- 3.Select your network and enter the password.
You can also reconnect using WPS if your router supports it: press and hold the printer's Wi-Fi button for 5 seconds until the light starts flashing, then within 2 minutes press and hold the WPS button on the router until the connection begins, and wait for the wireless light to stop flashing. Reconnecting through the HP app is another option if you would rather drive it from your phone or computer.
Refresh an Outdated or Corrupt Print Driver
Outdated or corrupt drivers can leave the printer stuck offline, and this is especially common right after an operating system update changes how the driver talks to the printer. On Windows, the Diagnose & Fix tool can check for available driver updates, so it may already have handled this for you.
If you want a clean install, download the latest driver and the HP app from HP's official drivers portal for the OfficeJet Pro 9015e. On macOS, the cleanest way to load a fresh driver is the printing-system reset in the next fix, which re-adds the printer with current software.
Reset the Printing System on a Mac
When a Mac keeps showing the 9015e as offline even after the steps above, resetting the macOS printing system gives you a clean slate. This is more aggressive than the earlier fixes, so read the warning before you proceed.
- 1.Open "Printers & Scanners" (search for it via Spotlight).
- 2.Right-click (or Control-click) in the Printers list and select "Reset printing system".
- 3.Restart the printer.
- 4.Click "Add Printer, Scanner, or Fax" (the Add button), select your printer, and click "Add".
Be aware that resetting the printing system removes all printers and scanners and clears print jobs and saved settings. Every printer must be set up again afterward, so use this when the simpler steps have not worked.
Put the Printer Back Into Wi-Fi Setup Mode
If Wi-Fi still will not connect, you can reset just the network settings without wiping everything else on the printer. This clears bad network settings and returns the 9015e to setup mode so the app can find it fresh.
- 1.On the printer control panel, touch the Setup icon or Wireless icon.
- 2.Select "Network setup" or "Settings".
- 3.Select "Restore Network Settings".
- 4.If a confirmation prompt displays, touch "Yes".
Wait 60 seconds until the Wireless light blinks blue, then within two hours return to the HP app or printer software to find and add the printer. Acting within that two-hour window matters, because the printer leaves setup mode after it expires.
Run a Full Factory Restore as a Deeper Reset
When network-only resets do not fix the problem, restoring factory defaults clears deeper misconfigurations on the printer itself. This is a heavier step that wipes the printer's settings, so you will need to set up Wi-Fi again and reinstall the printer on your devices afterward. Only use it once the lighter fixes above have failed.
- 1.On the printer control panel, touch the Setup or Menu icon (you might need to swipe down on the touchscreen first to open the printer Dashboard).
- 2.Touch "Tools", or "Printer Maintenance".
- 3.Touch "Restore".
- 4.Touch "Restore Factory Defaults".
- 5.Confirm with "Yes" (or "Continue" / "Restore").
A "Restoring printer factory defaults" message displays, and the printer automatically restarts after about 20 seconds. Once it is back up, run the Wireless Setup Wizard (Fix 5) to rejoin your network.
When to Hand It Off to HP's Tools and Support
If the 9015e is still offline after a factory restore, the issue may need HP's automated diagnostics or a person. Start with HP's automated diagnostic tools on its printer-offline help page, which can walk you through targeted checks for your exact situation.
If that does not resolve it, contact HP Support directly. It is worth reaching out before assuming the printer has failed, since a setup or account issue can often be cleared up faster than you expect.
Frequently Asked Questions
Why does my HP OfficeJet Pro 9015e keep going offline even though it is on?
An "offline" status almost always means a dropped connection or a stuck setting rather than a powered-down printer. Power-cycle the printer, router, and your computer, confirm both devices are on the same network and band, and on Windows make sure "Use Printer Offline" and "Pause Printing" are not selected in the print queue.
What is the fastest way to fix an offline 9015e automatically?
Run Diagnose & Fix in the HP app. It is HP's official automated troubleshooter, it checks whether the printer is offline, and it works to reconnect it and resolve common print problems on both Windows and macOS. If the HP app is not available on your operating system, HP Smart provides the same full-feature support.
Does resetting fix Wi-Fi without erasing all my printer settings?
Yes. Use "Restore Network Settings" from the control panel (Setup or Wireless icon, then "Network setup" or "Settings") to clear bad network settings only. Wait 60 seconds for the Wireless light to blink blue, then add the printer from the HP app within two hours. A full "Restore Factory Defaults" is the heavier option that wipes everything and requires complete setup again.
Is the OfficeJet Pro 9015e a 2.4 GHz-only printer?
No. Per HP's datasheet, the 9015e is compatible with both 2.4 GHz and 5.0 GHz operations, making it a dual-band printer. If your router separates the two bands into different network names, join the printer and your computer or phone to the same band so they can find each other.
What do I do if none of these fixes bring it back online?
Use HP's automated diagnostic tools on its printer-offline help page, or contact HP Support directly. Reaching out before assuming the printer has failed is worth it, since many offline cases come down to a setup or network issue rather than a hardware fault.
