Nothing is more frustrating than clicking “Print” and finding that Windows cannot see your printer at all. This guide on How to Fix a Printer Not Detected by Windows covers every common cause, from loose USB cables and expired drivers to the print spooler service that quietly stops working in the background. Follow the steps in order — most cases are resolved within the first few.
“Not detected” usually means one of three things: Windows has never seen the printer (a setup problem), Windows lost track of it (a driver or network problem), or Windows is looking in the wrong place (a connection problem). The fixes below are organized so you spend the least time on the most likely causes first.
Quick Answer
To fix a printer not detected by Windows: check the USB cable or Wi-Fi connection, restart the printer and PC, go to Settings → Bluetooth & devices → Printers & scanners and click “Add device”, run the built-in printer troubleshooter, restart the Print Spooler service, and reinstall the latest driver from the printer manufacturer’s official website. For network printers, make sure the printer is on the same Wi-Fi network as your PC.
How to Fix a Printer Not Detected by Windows: Start With the Physical Checks
Before touching any software, rule out the hardware basics — they cause a surprising share of “not detected” reports:
- Power: the printer should show a steady power light. A blinking light usually means an error state (paper jam, open cover, empty cartridge) that blocks detection.
- USB cable: unplug the cable at both ends and plug it back in firmly. Try a different USB port on the PC — front-panel ports on desktops can be unreliable. If you suspect the cable itself, swap it: a damaged cable is a classic invisible culprit.
- Wi-Fi printers: confirm the printer is actually connected to your network — print its network configuration page from the printer’s menu. If the printer will not join Wi-Fi at all, fix that first with our guide on how to fix a printer not connecting to Wi-Fi.
- Same network: your PC and the printer must be on the same Wi-Fi network. If your PC is on “Home_5G” and the printer is on “Home”, Windows will not find it. This is the single most common cause for wireless printers.
Step 1: Add the Printer Manually in Windows Settings
Windows 10 and 11 usually discover printers automatically, but a manual add often succeeds where auto-discovery fails:
- Open Settings → Bluetooth & devices → Printers & scanners.
- Click Add device (Windows 11) or Add a printer or scanner (Windows 10).
- Wait a full minute for the scan to finish — network printers can be slow to appear.
- If your printer appears, select it and click Add device.
- If it does not appear, click “The printer that I want isn’t listed” and try each option in turn: “My printer is a little older” (USB), “Add a printer using a TCP/IP address” (network — use the IP from the printer’s network report), or “Add a Bluetooth, wireless or network discoverable printer”.
Step 2: Run the Windows Printer Troubleshooter
The built-in troubleshooter fixes detection problems automatically more often than people expect:
- Open Settings → System → Troubleshoot → Other troubleshooters.
- Click Run next to Printer.
- Follow the prompts and apply any fixes it suggests, then restart your PC.
Microsoft’s own support documentation explains the full range of what this tool can repair — see Microsoft Support for the latest troubleshooting steps if the built-in tool reports a problem it cannot fix.
Step 3: Restart the Print Spooler Service
The Print Spooler is the Windows service that manages printing. When it stalls, printers vanish from the device list even though the hardware is fine:
- Press Windows key + R, type services.msc, and press Enter.
- Scroll to Print Spooler, right-click it, and choose Restart.
- Double-click it and confirm Startup type is set to Automatic.
- Try adding the printer again.
If the spooler keeps stopping on its own, a corrupted driver or a stuck print job is usually the cause — clear any jobs from the print queue first (Settings → Printers & scanners → your printer → Open print queue → cancel all documents), then continue to the driver steps below.
Step 4: Update or Reinstall the Printer Driver
Drivers are the leading cause of printers that worked yesterday and are invisible today, especially after a Windows update. A clean reinstall beats an update in most cases:
- In Printers & scanners, remove the printer if it is listed.
- Go to Device Manager (right-click Start → Device Manager), expand Printers or Print queues, right-click the printer entry, and choose Uninstall device.
- Restart the PC.
- Download the latest driver from your printer manufacturer’s official website — for example, the Canon official website — choosing your exact model and Windows version. Avoid driver-download sites and “driver updater” tools; they are a common source of malware.
- Install the driver with the printer connected (USB) or powered on and on the network (Wi-Fi), then add the printer again in Settings.
Tip: if the manufacturer offers a “full feature software” package and a “basic driver”, the full package includes the scanning and maintenance tools — useful if you also use your device as a scanner. Our guide on how to connect a scanner to Windows covers the scanning side in detail.
Step 5: Check Windows Firewall and Network Discovery
For network printers, Windows security settings can block discovery even when everything else is correct:
- Network profile: go to Settings → Network & internet → Wi-Fi (or Ethernet) and make sure the network is set to Private, not Public. Windows blocks printer discovery on Public networks.
- Network discovery: in Control Panel → Network and Sharing Center → Advanced sharing settings, turn on network discovery and file and printer sharing for the Private profile.
- Firewall: if you use a third-party antivirus with its own firewall, temporarily disable it and test. If the printer appears, add an exception for printer sharing rather than leaving the firewall off.
- VPN: disconnect any active VPN — VPNs route traffic away from your local network, making local printers invisible.
USB vs Network Printers: What Changes
| Connection type | Most likely cause | First thing to try |
|---|---|---|
| USB | Cable, port, or driver problem | Swap cable and port, then reinstall the driver (Step 4) |
| Wi-Fi | Different networks, or printer dropped Wi-Fi | Confirm both devices on the same SSID, then re-run printer Wi-Fi setup |
| Ethernet | Cable or router port issue | Check link lights on the printer’s Ethernet port; try a different router port |
| Shared (another PC) | Sharing disabled on the host PC | Enable printer sharing and network discovery on the host computer |
Step 6: Set the Printer as Default and Test
Once Windows detects the printer, finish the job properly:
- In Printers & scanners, click your printer and choose Set as default.
- Turn off “Let Windows manage my default printer” — this setting silently switches the default to whichever printer you used last, which confuses many users.
- Click Print a test page from the printer’s settings page.
If the test page prints but everyday documents do not, the issue is now application-specific rather than detection — for that, see our guide on how to fix a printer not printing.
When the Printer Is Detected But Shows as Offline
Sometimes Windows finds the printer but greys it out as “Offline”. Quick fixes: right-click the printer and uncheck “Use Printer Offline” if it is enabled; restart the Print Spooler (Step 3); and for Wi-Fi printers, give the printer a reserved IP address in your router so Windows stops losing track of it. Our full walkthrough on how to fix printer offline problems covers this scenario in depth.
Frequently Asked Questions (FAQs)
Why is my printer connected to Wi-Fi but not showing up in Windows?
The two most common reasons are that the PC and printer are on different Wi-Fi networks (for example 2.4 GHz vs 5 GHz bands with separate names), or the PC’s network is set to Public, which blocks discovery. Check both, then run the manual add in Step 1.
How do I find my printer’s IP address?
Print a network configuration report from the printer’s own menu (usually under Settings → Reports or Network). Alternatively, check your router’s connected-devices list. Once you have the IP, you can add the printer manually in Windows using the “TCP/IP address” option, which often succeeds when auto-discovery fails.
Should I use the Windows built-in driver or the manufacturer’s driver?
Use the manufacturer’s driver from their official website. Windows’ built-in drivers cover basic printing but often lack scanning, ink-level reporting, and duplex controls. After major Windows updates, reinstalling the manufacturer driver is the fix that works most often.
My printer worked yesterday and is gone today. What happened?
Almost always one of three things: a Windows update replaced or broke the driver (reinstall it per Step 4), the printer received a new IP address from the router (add it again manually, or reserve its IP in the router), or the Print Spooler service stopped (restart it per Step 3).
Can a VPN stop Windows from detecting my printer?
Yes. A VPN tunnels your traffic away from the local network, so network printers become invisible while it is connected. Disconnect the VPN when printing, or configure split tunnelling in your VPN app to exclude local network traffic.
Is it safe to download printer drivers from third-party driver sites?
No. Only download drivers from the printer manufacturer’s official website or through Windows Update. Third-party driver sites frequently bundle adware or malware, and fake “driver updater” tools are a well-known scam vector.
The Bottom Line
How to Fix a Printer Not Detected by Windows almost always comes down to the same sequence: verify the physical connection, add the printer manually, run the troubleshooter, restart the Print Spooler, and do a clean driver reinstall from the manufacturer’s official site. For wireless printers, the extra check is that PC and printer share the same network and the PC’s profile is Private. If the printer remains invisible after all of this — including on a different computer — the printer’s own USB port or network hardware may have failed, in which case check your warranty: UAE consumer protection laws cover manufacturing defects within the warranty period, so keep your receipt and contact the retailer’s service centre.
