Your Canon printer sits there. You hit print. Nothing happens. The queue fills up, the status shows offline even though it's clearly on, and you've got documents piling up in the Windows print queue like a traffic jam nobody's moving.
This is one of the most common printer problems, and the good news is that nine times out of ten you don't need to call Canon support or buy a new printer. It's almost always a software issue, either your connection's dodgy, the print spooler's jammed up, or the driver's out of date. I've fixed this scenario hundreds of times via remote support, and I'll walk you through the exact steps that actually work.
TL;DR
Canon printer not responding to print commands? Restart both the printer and Windows, verify cable connections, set Canon as your default printer, and run the Windows Printer Troubleshooter. If that fails, stop the Print Spooler service, delete the stuck jobs from the spool folder, and restart the spooler. Check Windows Firewall isn't blocking the printer, then uninstall and reinstall the latest Canon driver from the official UK website. Success rate: 80% without driver reinstall.
Key Takeaways
- Canon printer not responding to print commands is usually caused by connection failures, corrupted print spooler, outdated drivers, or firewall blocks, not hardware defects
- Most cases resolve with basic restarts, clearing the print queue, and setting the correct default printer
- Only 20% of cases require driver reinstallation; troubleshoot the spooler and firewall first
- Network printers are more prone to this issue than USB-connected ones, especially after Windows updates
- Prevention involves regular driver updates and monthly spooler maintenance

What Causes Canon Printer Not Responding to Print Commands?
Before you start troubleshooting, you need to understand why this happens. Canon printers fail to respond to print commands for five main reasons, and they rarely overlap. If you know which one's affecting you, you can skip straight to the right fix.
Connection problems are the biggest culprit. USB cables come loose from repeated use, or they get bent behind a desk and develop internal shorts. Network printers lose connection when your router restarts, when you switch between your home Wi-Fi and a mobile hotspot (a rookie mistake that breaks everything), or when someone reboots the router at 3pm without telling anyone. The printer stays powered on, but Windows can't talk to it.
Print spooler failures are the second major cause. The Print Spooler service is a Windows background process that queues print jobs and sends them to the printer one at a time. When a corrupted print job gets stuck in the queue, it blocks all subsequent jobs. The spooler can't clear it, so nothing prints. You end up with a queue full of jobs that won't go anywhere, and Windows stops responding to new print commands entirely.
Driver incompatibility hits hard after Windows updates. Canon releases drivers for Windows 10 and Windows 11, but when Microsoft pushes a major update, sometimes the driver stops talking properly to the new Windows version. This is especially common after the October update cycle. The driver thinks the printer is offline even though it's not.
Windows Firewall and security software blocks printer ports. Windows Firewall isn't your only concern, antivirus programs, VPN clients, and security suites can all intercept printer communication. The PrintNightmare security patch (which blocks error 0x0000011b) sometimes prevents network printers from connecting at all if you haven't configured the right registry setting.
Printer configuration errors happen more often than you'd think. If you've accidentally set the Canon printer to 'Use Printer Offline' mode, Windows won't send jobs to it. Or you might have set a different printer as default without realising it, so your print commands route to a printer that doesn't exist or can't be found.
Canon Printer Not Responding to Print Commands: Quick Fix
Basic Connection and Restart Procedure Easy
This fix clears 60-80% of cases because it resets both the printer and Windows simultaneously. You're not installing anything, just turning things off and on in the right order.
- Power cycle the printer
Turn off the printer using the power button. Unplug the power cable from the mains outlet. Wait 60 seconds (yes, actually count it, this clears the printer's memory). Plug the cable back in and turn the printer on. Wait for the Status LED to illuminate steadily. This resets the printer's internal communication buffers. - Restart Windows PC
Don't just sleep or hibernate. Click Start > Power > Restart and let the PC do a full boot cycle. This resets the Windows print subsystem and re-establishes network connections. - Verify physical connections
For USB printers: check the cable is firmly seated at both the printer and PC ends. Try a different USB port on your PC, some ports have power issues. For network printers: confirm the printer is connected to your home Wi-Fi (never use a mobile hotspot for printers, it breaks DHCP), and check that your router lights are on. Make sure Bluetooth is disabled on the printer if it has that feature. - Set Canon as default printer
Press Windows+R, typecontrol, press Enter. Navigate to Devices and Printers. Right-click your Canon printer, select 'Set as default printer'. Make sure the checkbox for 'Use Printer Offline' is unchecked. This routes future print commands to the correct device. - Run Windows Printer Troubleshooter
Open Settings > System > Troubleshoot > Other troubleshooters. Find Printer and click Run. Follow the on-screen prompts and let Windows apply the recommended fixes automatically. - Test the printer
Right-click your Canon printer in Devices and Printers, select 'Printer properties', click the 'Print Test Page' button. If a test page comes out, the printer is responding. If nothing happens, move to the next solution.
More Canon Printer Not Responding Solutions
Clear Print Spooler and Queue Intermediate
If basic restarts didn't work, the print spooler has probably accumulated corrupted jobs. This solution stops the spooler service, deletes all stuck print jobs, and restarts it with a clean slate. Success rate jumps to 50-60% when you combine this with firewall checks.
- Open Services management
Press Windows+R, typeservices.msc, press Enter. Scroll down and locate the 'Print Spooler' service in the list. You'll see its status, it should say 'Running' right now. - Stop the Print Spooler service
Right-click 'Print Spooler', select 'Stop'. The status will change to 'Stopped'. This halts the print queue immediately and stops new jobs from being processed. - Clear stuck print jobs
Press Windows+R, typespool, press Enter. A folder window opens showing your spool directory. Navigate to the PRINTERS subfolder. Select all files inside (Ctrl+A), press Delete. Confirm deletion if Windows asks. These are the corrupted jobs jamming up your queue. Note: if the PRINTERS folder is empty, spooler corruption wasn't your problem, skip to firewall checks. - Restart Print Spooler
Return to the services.msc window. Right-click 'Print Spooler' again, select 'Start'. Wait for status to show 'Running'. This reinitialises the print queue with a clean slate. - Check Windows Firewall settings
Open Windows Security by typing it in the Start menu. Go to Firewall & Network Protection. Click your active network profile (usually 'Private network'). Toggle 'Windows Defender Firewall' to Off temporarily. Attempt a test print, if it works, firewall is blocking the printer. - Re-enable firewall with exception
If the print succeeded, toggle the firewall back On. Click 'Allow an app through firewall', find your Canon printer software in the list, and enable it for both 'Private' and 'Public' networks. This maintains security while permitting printer access.
Advanced Canon Printer Not Responding Fixes
Driver Update and Reinstallation Advanced
This is the nuclear option and works for 40-70% of persistent cases. Outdated drivers, corrupted installations, and PrintNightmare security patches all require a fresh driver. Registry edits are involved, so create a system restore point first. Similar connectivity issues affect other devices too, if you've had network communication problems on your PC before, driver conflicts might be part of a broader pattern.
- Create a System Restore point
Search 'Create a restore point' in the Start menu, click the match. Click the 'Create...' button, name it 'Before Canon Driver Update', click Create. Wait for the confirmation message. This gives you a rollback option if the driver installation goes sideways. - Uninstall the existing Canon driver
Open Settings > Bluetooth & devices > Printers & scanners. Find your Canon printer, click it, select 'Remove'. Then press Windows+X, click 'Device Manager'. Expand 'Print queues', right-click your Canon printer entry, select 'Uninstall device'. Tick the box that says 'Delete the driver software for this device', click Uninstall. This removes every trace of the old driver. - Download the latest driver
Go to canon.co.uk/support, search for your printer model, select your Windows version from the dropdown (Windows 10 or Windows 11), and download the full driver package, not the 'basic driver'. Save it to your Downloads folder. Verify the file is roughly 200+ MB; if it's smaller, you downloaded the wrong version. - Install the new driver
Locate the downloaded file, right-click it, select 'Run as administrator'. Follow the installation wizard. When prompted, select your connection type: 'USB Connection' or 'Network Connection'. If USB, don't plug in the cable until the installer tells you to. If network, the installer will search your Wi-Fi for the printer. Don't restart yet, let the installer finish completely. - Perform a full Windows restart
After the driver installation finishes, click Start > Power > Restart. The restart finalises driver registration with Windows and loads the new driver into memory. This is a full restart, not a sleep or hibernation. - Fix PrintNightmare error (network printers only)
If you see error 0x0000011b or the printer shows as offline despite being connected, the PrintNightmare security patch is blocking you. Press Windows+R, typeregedit, press Enter. Navigate toHKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print. Right-click the 'Print' folder, select New > DWORD (32-bit) Value. Name itRpcAuthnLevelPrivacyEnabled, set the value to 0, click OK. Restart the PC. This disables the privacy restriction blocking network printer connections. Warning: this reduces network security for printing only, so only use it if absolutely necessary. - Manually add the printer via IP address (if auto-detection fails)
If the printer doesn't appear in Devices and Printers after the driver installs, add it manually. Go to Settings > Bluetooth & devices > Printers & scanners > Add device > Add manually. Select 'Add a printer using a TCP/IP address or hostname'. Get the printer's IP address from its network settings page (usually accessed via the printer's menu button), enter it, and follow the wizard to completion. This bypasses auto-discovery and establishes a direct network connection.
Preventing Canon Printer Not Responding Issues
Once you've fixed this, keep it fixed. Canon printer not responding to print commands is preventable with minimal effort.
Update drivers quarterly. Visit the Canon UK support website every three months, search your printer model, and check if a new driver is available. After every major Windows update (roughly October and April), check immediately. Don't wait for problems to happen. If you're dealing with driver issues across multiple devices, the underlying cause might be device driver conflicts generally, so audit all your drivers.
Maintain your print queue monthly. This takes five minutes. Stop the Print Spooler service, delete all files in the spool\PRINTERS folder, restart the spooler. It's preventive maintenance, you're clearing out junk before it becomes a crisis.
Use your home Wi-Fi, never mobile hotspots. Mobile hotspots cause DHCP issues that make printers disappear from the network. Always use your home Wi-Fi router for printer connections. Guest networks sometimes work, but not reliably.
Configure firewall exceptions immediately after driver install. The moment the new driver is installed, go to Windows Firewall settings and add the Canon printer software to the allowed apps list for both Private and Public networks. Don't wait until the printer stops working.
Always set Canon as your default printer. Don't rely on 'remember my choice', manually set Canon as default in Devices and Printers. Verify quarterly that it's still set correctly, especially if you've added other printers.
Create System Restore points before major Windows updates. When Microsoft releases a quarterly Windows update, create a restore point first. Search 'Create a restore point', click Create, name it with the date and update type, click Create. If the update breaks your printer, you can roll back to the restore point.
Check printer firmware updates. Canon pushes firmware updates through its printer management software. Open the Canon software, check for printer updates, and install them. Firmware fixes communication bugs that drivers alone can't address.
Canon Printer Not Responding Summary
Canon printer not responding to print commands is frustrating, but it's almost never a hardware problem. Start with the basic restart and default printer check, that clears 60% of cases in five minutes. If that doesn't work, clear the print spooler and check your firewall. Only if you're still stuck do you need to reinstall the driver, and even then, success is likely because you're giving Windows a clean slate to work with.
The key is methodical troubleshooting. Test after each step. Don't skip firewall checks just because you think firewall isn't the problem, I've seen firewall blocks cause canon printer not responding issues more times than I can count. If driver reinstallation is needed, create a restore point first so you can roll back if things go sideways.
And once you get it working, do the monthly spooler maintenance and quarterly driver checks. Five minutes of prevention beats an hour of troubleshooting every single time.
