If your HP OfficeJet Pro 8620 suddenly stopped printing on Windows 11, you’re not alone. Many users report that the printer shows ready, ink is fine, and even resets don’t help — yet nothing prints.

The good news: in most cases, this issue is caused by a driver, connection, or spooler problem — not a hardware failure.

In this guide, you’ll learn the exact fixes that restore printing on Windows 11.

Why HP OfficeJet Pro 8620 Stops Printing in Windows 11

After Windows 11 updates or network changes, the printer may stop responding due to:

• Outdated or incompatible HP driver
• Windows print spooler errors
• Printer stuck offline
• Wrong default printer selected
• Wi-Fi communication failure
• Corrupted print queue

Even if the printer powers on normally, Windows may not send print jobs correctly.

Fix 1: Check If Printer Is Set as Default

Windows sometimes switches printers automatically.

Steps:

1. Open Settings
2. Go to Bluetooth & devices → Printers & scanners
3. Select HP OfficeJet Pro 8620
4. Click Set as default

Try printing again.

Fix 2: Clear Stuck Print Queue

A frozen job can block all printing.

Steps:

1. Open Printers & scanners
2. Click HP OfficeJet Pro 8620
3. Open Print queue
4. Cancel all documents

Now restart printer and PC.

Fix 3: Restart Windows Print Spooler

The spooler service manages printing. If it crashes, printer stops.

Steps:

1. Press Windows + R
2. Type: services.msc
3. Find Print Spooler
4. Right-click → Restart

Try printing test page.

Fix 4: Reinstall HP OfficeJet Pro 8620 Driver (Most Effective)

Windows 11 often installs a generic driver that breaks printing.

Steps:

1. Go to Settings → Printers & scanners
2. Remove HP OfficeJet Pro 8620
3. Restart PC
4. Download driver from 123.hp.com
5. Install using HP setup
6. Add printer again

This fixes most Windows 11 printing failures.

Fix 5: Check Printer Status (Offline Issue)

If printer shows offline, jobs won’t print.

Steps:

1. Open printer queue
2. Click Printer menu
3. Uncheck:
   • Use Printer Offline
   • Pause Printing

Fix 6: Verify Ink and Cartridge Detection

Even with ink installed, detection errors can block printing.

Steps:

1. Open printer front door
2. Remove cartridges
3. Reinsert firmly
4. Close door
5. Wait for calibration

Check printer screen for errors.

Fix 7: Run HP Print and Scan Doctor

HP’s official tool fixes connection and driver issues automatically.

Steps:

1. Download HP Print and Scan Doctor
2. Run tool
3. Select OfficeJet Pro 8620
4. Click Fix Printing

Many users restore printing within minutes using this tool.

Fix 8: Check Wi-Fi Connection (Wireless Models)

If printer lost Wi-Fi connection, Windows can’t send jobs.

Steps:

1. On printer screen → Wireless icon
2. Confirm connected network
3. Compare with PC Wi-Fi network
4. If different → reconnect printer Wi-Fi

When Hard Reset Doesn’t Fix Printing

You mentioned trying a hard reset — that’s good.
But resets only clear temporary states, not Windows driver or spooler issues.

So if reset + ink check didn’t help, the cause is almost always:

✔ Driver mismatch
✔ Windows spooler
✔ Connection problem

Quick Test: Print Directly From Printer

Try printing:

Setup → Reports → Print Quality Report

If this prints → printer hardware is fine
Problem is Windows side

If your HP OfficeJet Pro 8620 is not printing on Windows 11 even after reset and ink checks, the issue is usually software-related — not the printer itself.
