HP OfficeJet Pro 8620 Driver
The HP OfficeJet Pro 8620 is a feature‑rich small‑office all‑in‑one with duplex printing, an ADF, touchscreen controls, Wi‑Fi and Ethernet, and a reliable fax engine. To get all of those features—especially duplex scanning and HP’s maintenance tools—you need the correct driver package. A generic Windows or AirPrint driver can print, but you may lose scan shortcuts, ink monitoring, or stable network communication. This guide shows where to get the official 8620 drivers, how to install them on Windows and macOS, and how to fix common driver‑related errors.
Download the Correct 8620 Driver
Go to HP’s support site and search for OfficeJet Pro 8620 or the OfficeJet Pro 8600 series. Download the latestFull Feature Software and Drivers package for your operating system. HP Smart is also supported and is convenient for mobile setup, but the full package provides the richest scanning and fax utilities. Avoid third‑party driver sites to reduce malware and version mismatch risks.
Choose Your Connection Method First
The installer asks how you want to connect. Pick one before starting:
- Wi‑Fi: flexible placement; the printer prefers 2.4 GHz for range.
- Ethernet: best reliability for offices.
- USB: simplest single‑PC connection and useful for diagnostics.
Connect the Printer to Wi‑Fi
On the touchscreen, tap Wireless > Settings > Wireless Setup Wizard. Select your SSID and enter your password. If the printer was on an old network, choose Restore Network Defaults first. Once connected, print a Network Configuration Page to capture the current IP address.
Ethernet Setup
Plug an Ethernet cable into the printer and your router or switch. The printer will obtain an IP automatically. For long‑term stability, reserve the printer’s IP in your router so the Windows TCP/IP port never drifts.
Install on Windows 10/11
- Run the HP installer you downloaded.
- Select your connection type when prompted.
- Let the installer detect the 8620 on the network.
- If detection fails, connect USB temporarily so the installer can finish discovery.
After installation, open Settings > Printers & scanners, select the printer, and print a test page. Then open HP’s scan app and confirm that ADF and duplex scan options appear.
Install on macOS
Install HP Smart or HP Easy Start, then add the printer in System Settings > Printers & Scanners. In the Usedropdown, choose the HP driver (not AirPrint‑only) if you want full maintenance features. If the printer is not discovered automatically, add it by IP using protocol IPP.
Enable Scan to Computer and ADF Features
Open HP Smart on your computer and enable Scan to Computer. This registers your PC/Mac so you can start scans from the printer panel. If scans show thin lines, clean both the main glass and the ADF strip. For multi‑page PDFs, 300 DPI is ideal for text; higher DPI is only needed for photos.
Fax Setup (Optional)
Connect a phone line to the LINE port and run the fax wizard on the printer. If you have DSL, use a filter. Send a test fax to make sure the line is clean before you depend on it for work documents.
Fix “Driver Unavailable” or Missing Features
If Windows says driver unavailable, remove the printer, uninstall HP software from Apps, reboot, and reinstall the newest 8600‑series package. On a Mac, delete the printer, install HP Smart, and add it again with the HP driver selected. Missing scan buttons usually mean the basic driver is installed instead of the full suite.
Fix Printer Offline Errors
The OfficeJet Pro 8620 often goes offline in Windows when it’s using a WSD port. Fix it by:
- Printing a network report and noting the current IP.
- Opening Printer properties > Ports and choosing a Standard TCP/IP port matching that IP.
- Clearing stuck jobs and unchecking Use Printer Offline.
- Reserving the printer IP in your router.
Firmware Updates and Maintenance
Use HP Smart or the Embedded Web Server (open the printer IP in a browser) to check firmware. Firmware updates can improve Wi‑Fi stability and ADF behavior. For print quality issues, run printhead cleaning and alignment from the HP utility. The 8620 uses HP 950/951 cartridges; XL versions are cost‑effective for offices.
HP Smart, ePrint, and Mobile Features
Even on an older 8600‑series printer, HP Smart is worth keeping installed. It shows supply levels, runs maintenance tasks, and lets you scan to your computer or phone without juggling multiple utilities. Many OfficeJet Pro 8620 units also support HP ePrint or email printing, which can be helpful if you need to send jobs remotely. If you enable ePrint, make sure your router allows the printer to reach the internet; otherwise, keep it off and rely on local Wi‑Fi printing.
USB Setup as a Diagnostic Step
If wireless discovery keeps failing, connect the printer by USB and install the driver that way first. Once you can print and scan over USB, rerun the HP installer and switch the connection to Wi‑Fi or Ethernet. This approach saves time because it proves the driver stack is healthy before you troubleshoot the network.
With the right driver installed and a stable network port, the HP OfficeJet Pro 8620 becomes a dependable printer, scanner, and fax for everyday office work.
