HP Printer Not Working? Step-by-Step Fix Guide

HP is the world's most popular printer brand, and with that popularity comes a lot of troubleshooting questions. If your HP printer is not working, you're not alone — HP printers have specific quirks related to their drivers, HP Smart app, and WiFi connectivity that require targeted fixes.

This guide covers all current HP printer lines: DeskJet (home/basic), OfficeJet (all-in-one), LaserJet (laser/business), and ENVY (photo/premium). Each fix is written specifically for HP's software, tools, and common failure points.

HP Printer Diagnostic Tool — HP Print and Scan Doctor

Before trying manual fixes, run HP's own diagnostic tool — it automatically detects and fixes most issues:

1. Download HP Print and Scan Doctor from support.hp.com (it's free)
2. Run the tool — it scans for printer problems automatically
3. It checks: driver status, connectivity, print queue, spooler service, and port configuration
4. The tool will offer to fix any issues it finds — click "Fix" for each
5. This single tool resolves about 60% of HP printer not working issues

Fix 1: Power Cycle Your HP Printer

HP printers store temporary data that can cause issues. Turn the printer on, then disconnect the power cable from the back of the printer(not just the wall). Wait 60 seconds. Reconnect and power on. This clears the printer's internal memory and resets error states. HP specifically recommends this as the first troubleshooting step for all their models.

Fix 2: Fix HP Printer Offline Status

"Offline" is the #1 HP printer complaint. Here's the complete fix:

1. Open Settings → Bluetooth & devices → Printers & scanners
2. Click your HP printer → Open print queue
3. Click Printer menu → uncheck "Use Printer Offline"
4. If that doesn't work, also uncheck "Pause Printing"
5. If still offline, restart the Print Spooler: run services.msc → find Print Spooler → right-click → Restart
6. For persistent offline issues, see our detailed printer offline fix guide

Fix 3: Reinstall HP Printer Driver

HP driver issues are especially common after Windows updates:

1. First, remove the current printer: Settings → Printers → Remove device
2. Visit support.hp.com
3. Enter your exact model number (printed on front of printer, e.g., "HP DeskJet 4155e")
4. Download the "HP Smart" app (recommended) or "Full Solution" driver
5. Install and follow the setup wizard — it will detect and configure your printer

Fix 4: Connect HP Printer to WiFi

If your HP printer lost its WiFi connection:

• Touchscreen models: Printer menu → Settings → Wireless → Wireless Setup Wizard → select your network → enter password
• Non-touchscreen: Press and hold the Wireless button + WPS button on router within 2 minutes
• HP Smart app: Open app → Add Printer → follow on-screen instructions (easiest method)
• Important: HP printers only connect to 2.4 GHz WiFi — make sure your router broadcasts this band
• If your router was recently restarted, the printer may need to reconnect — the IP address may have changed

Fix 5: Reset HP Printer Network Settings

If WiFi setup keeps failing, reset the printer's network settings completely: On the printer, go to Settings → Network → Restore Network Settings. The printer will restart and forget all WiFi connections. Then set up WiFi from scratch using the Wireless Setup Wizard or HP Smart app.

Fix 6: Fix HP Ink Cartridge Issues

• "Cartridge Problem" error: Remove cartridges, clean the gold contacts with a lint-free cloth, reinsert firmly
• "Incompatible Cartridge": Make sure you're using the correct cartridge number for your specific model — check inside the cartridge bay for a label
• Non-HP cartridge warnings: HP printers may warn about third-party cartridges but should still print — click "OK" to proceed
• New cartridge not working: Remove the orange protective tape AND the small plastic clip covering the contacts
• Print head cleaning: HP Smart app → Printer Maintenance → Clean Printhead (run 2-3 times for stubborn clogs)

Fix 7: Clear Print Queue and Spooler

Fix 8: Check HP Error Codes Before Replacing Parts

Many HP issues look like hardware failures but are actually recoverable software or communication errors. Before you replace cartridges, printheads, or the printer itself, check the exact error shown on the panel or in HP Smart.

• E0 / E1 / E2: Usually paper feed, paper size, or tray alignment issues. Remove jammed paper and reload correctly.
• 79 Service Error: Typically corrupted print jobs or firmware conflicts. Restart, clear the queue, and update firmware.
• Supply System Problem: Cartridge recognition issue. Remove cartridges, clean contacts, re-seat, and run maintenance.
• Printhead Missing / Failed: Re-seat printhead and run printhead cleaning. If unresolved, use genuine replacement parts.
• Wireless Setup Failed: Reset network settings and reconnect using 2.4 GHz WiFi or HP Smart guided setup.

Fix 9: Keep HP Firmware and Apps Updated

Outdated firmware is a common root cause for random disconnects, scan failures, and print quality glitches. Update both the printer firmware and HP Smart app to avoid repeat incidents.

1. Open HP Smart and select your printer.
2. Go to Advanced Settings or Printer Information.
3. Check for firmware updates and apply all recommended patches.
4. Reboot printer and computer after update completion.
5. Re-test using a test page and a multi-page print job.

When to Escalate for Remote Support

If your HP printer still fails after completing the steps above, the issue is usually tied to deeper driver conflicts, spooler corruption, Windows service policies, or router-level isolation rules. At that point, guided remote troubleshooting is faster than repeated trial-and-error. You can start from our support session page or use the contact form.
