You select a document, click Print, and nothing happens. Your printer is switched on, paper is loaded, and the WiFi light may even be steady—but your computer still displays Canon printer offline.
That message means your computer cannot communicate with the selected printer properly. It does not automatically mean the printer is broken. Canon’s troubleshooting guidance identifies communication problems, offline settings, and driver issues as things to check.
The best approach is to work out where printing stops: at the printer, on the network, or inside your computer’s print queue. Follow the relevant checks below, and try printing one page after each change.
A Canon printer showing offline can have several possible causes:
Canon recommends checking the selected printer driver and offline setting before moving on to network diagnostics or reinstalling the driver.
Before changing settings, note your printer’s exact model and whether it connects through WiFi, Ethernet, or USB. This helps you follow the correct instructions for your setup.
Check the printer’s display before troubleshooting your computer. If it shows a paper jam, an open cover, or another error, follow the model’s instructions to clear that message.
Next, restart the printer. Turn it off using its power button, wait until it finishes shutting down, disconnect the power for about 30 seconds, and reconnect it. Microsoft includes this power cycle among its recommended offline-printer checks.
For a USB connection, check that the cable is firmly attached at both ends. For wireless printing, continue with the network checks below.
A WiFi indicator alone does not tell you whether the printer and computer can communicate.
Check the network name on your computer, then compare it with the printer’s network information. Depending on the model, you can view this on its screen or print a network settings page. Canon recommends comparing these network names when troubleshooting an offline message.
Pay particular attention if you recently replaced your router or changed your WiFi name or password. Check which network the printer is using rather than assuming it followed your computer onto the new connection.
If your model supports Canon’s Wi-Fi Connection Assistant, use its diagnostic options to investigate the wireless connection. Availability and instructions depend on the printer model.
Go to:
Start → Settings → Bluetooth & devices → Printers & scanners
Select your Canon printer and choose Open print queue. Check that its model name matches the printer you intend to use.
If you have several similarly named entries, take a moment to identify the correct one before sending another document.
In the queue, cancel the pending jobs and try printing one short document. Microsoft recommends clearing pending jobs when troubleshooting a printer that appears offline.
Avoid clicking Print repeatedly while testing. A single test page makes it easier to see whether the latest change worked.
Some Canon driver interfaces provide a classic print queue with a Printer menu. If Use Printer Offline is selected, clear it.
For supported Canon IJ drivers, Canon documents a route through Print settings → Maintenance → View Printer Status → Display Print Queue. These options vary with the installed driver, so your screen may look different.
Open the Get Help app and run the printer troubleshooter. Follow its prompts, then test printing again. Microsoft recommends this diagnostic tool for Windows 11 printer problems.
For a Canon printer offline Windows 10 problem, open:
Start → Settings → Devices → Printers & scanners
Select your printer and choose Open queue. In the classic queue’s Printer menu, clear Pause Printing and Use Printer Offline if either is selected.
You can also select the correct printer as the default. This helps ensure future documents go to the intended device.
After changing the settings, send a fresh test document rather than relying only on a job that was already waiting.
If your Canon printer says offline after the connection and queue checks, review the installed driver.
Canon recommends making sure the printer name and driver match. Its guidance also identifies an old or incorrectly installed driver as a possible reason printing fails.
Use Canon’s official support page for your exact model and operating system. Follow the installation instructions supplied for that model.
If the existing printer entry still fails, removing and adding the printer again is another troubleshooting option documented by Microsoft.
For a Canon printer offline Mac problem, start with:
Apple menu → System Settings → Printers & Scanners
Select the printer and inspect its queue. Resume it if paused, and remove a failed job before trying again.
Also check that the printer selected in the application’s Print dialog is the one you intended to use. Apple recommends checking the queue, connection, and printer software when investigating printing problems.
If the problem continues, remove the affected printer entry and add it again using the appropriate software or AirPrint where supported. Reserve a full printing-system reset for cases where other troubleshooting has failed; Apple lists it as a later troubleshooting step.
When the problem returns, record what happened immediately beforehand. Useful details include:
These observations help you choose the next check instead of repeating every fix. For example, if another device can print successfully, investigate the affected computer’s queue and setup first.
Check its power and connection, open the correct print queue, and clear Use Printer Offline if that option is selected. Canon includes these checks in its offline troubleshooting guidance.
Check that the printer and computer use the intended network. Canon specifically recommends comparing their network names rather than relying only on the printer’s wireless indicator.
Start with the connection, selected printer, and offline setting. Canon places driver reinstallation after those earlier checks in its troubleshooting sequence.
Keep the model number, operating system, connection type, and any error message ready. Use the official troubleshooting instructions for that exact model to decide the next step.
