Canon Printer Offline — How to Get It Back Online
By Ryan Green · Updated July 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
This is one of the most frustrating printer problems because everything looks fine—your Canon is powered on, sitting right there—but Windows or Mac refuses to communicate with it. You'll see "Offline" status in your printer queue, print jobs won't go through, and restarting your computer doesn't help.
The good news: this almost never means your printer hardware is broken. It's a connection or software glitch, and we'll walk through the exact fixes a Canon service tech would use, starting with the simplest and moving to the advanced troubleshooting that actually works.
How to fix it — step by step
- Power cycle the printer properly. Turn off your Canon printer using the power button. Wait 30 seconds—this clears the printer's memory and resets its network connection. Turn it back on and wait for all lights to stop blinking and stabilize. This is not the same as unplugging it; use the power button for a clean shutdown.
- Check WiFi connection on the printer. On your Canon's control panel, navigate to Settings > Network > WiFi Settings (menu path varies by model). Confirm the printer shows a connected network name and has a signal indicator. If it shows "Not Connected," select your WiFi network, enter the password, and wait 20 seconds for connection. If WiFi icon shows red or X, the printer lost the network and this step will fix it.
- Restart the print spooler service (Windows only). Press Windows Key + R, type `services.msc`, and press Enter. Scroll down and find "Print Spooler." Right-click it, select "Restart." This service manages all print jobs and gets corrupted frequently. After restart, wait 10 seconds, then try printing a test page. On Mac, restart your computer instead, as macOS handles spooling differently.
- Remove and re-add the printer on Windows. Go to Settings > Devices > Printers & Scanners. Find your Canon printer, click it, select "Remove device," and confirm. Now click "Add a printer or scanner" at the top. Windows will search for 30 seconds. When your Canon appears, click it and select "Add device." Windows will install drivers automatically and your printer should show Online.
- Remove and re-add the printer on Mac. Open System Settings > Printers & Scanners. Click the lock icon to unlock settings if needed. Right-click your Canon printer in the list and select "Delete." Click the "+" button, search for your printer name, select it, and click "Add." macOS will re-establish the connection and download the latest driver. Check the printer is now showing as default or Available.
- Restart your WiFi router. Unplug your WiFi router for 10 seconds, then plug it back in. Wait 90 seconds for it to fully restart. Your Canon printer will automatically reconnect to the network once the router is back online. This resolves connectivity issues caused by router memory leaks or IP address conflicts. After the router is fully booted, open your printer queue and check if the printer shows Online.
- Update Canon printer drivers. Visit Canon's official support website, search for your exact printer model number (found on the back or in your manual), and download the latest driver package for your OS. On Windows, run the installer and restart your computer. On Mac, download the .dmg file and follow the installation prompts. Outdated drivers commonly cause offline status even with good connections.
- Check for IP address conflicts. On your Canon's control panel, print a Network Configuration Page: Settings > Network > Print Network Settings (exact path varies by model). Note the printer's IP address (looks like 192.168.1.100). On your computer, open a web browser and type that IP address into the address bar. If the Canon web page loads, the printer's network connection is fine and the issue is on the computer's software side. If the page won't load, the printer has lost its network identity and may need a factory reset.

Frequently asked questions
My Canon printer shows offline but the WiFi icon is lit on the printer—why?
A lit WiFi icon means the printer has a WiFi chip, not that it's successfully connected. Your printer may be connected to a different network than your computer, or the connection is unstable. Check the printer's network settings (Settings > Network) to confirm it shows your actual WiFi network name, not an old one. If it shows an old network name, delete it and reconnect to your current network.
I've done all these steps and it's still offline. What's wrong?
At this point, the issue is likely a deeper network configuration problem or printer firmware corruption. You can try a factory reset on the printer (Settings > Maintenance > Reset, then select Network Reset), but this will erase all saved settings. If that doesn't work, there's likely a hardware issue with the printer's network module, or you may benefit from professional remote support ($49 through Canon service partners) to diagnose the exact problem without replacement.
Why does this happen to Canon printers specifically?
This issue affects all printer brands, but Canon models are particularly prone to WiFi reconnection problems after Windows or macOS updates. Canon's network drivers aren't always updated immediately with OS patches, causing handshake failures. The good news: it's almost always fixable with the steps above and rarely indicates a hardware failure.
Should I use USB cable instead if WiFi isn't working?
Yes, a USB connection will bypass the WiFi problem and let you print immediately, which confirms your printer and computer can communicate. However, USB cables limit functionality (mobile printing won't work), so use this as a temporary workaround only. The WiFi issue will still need to be solved using the steps above if you want full printer features.
