Your Canon printer is powered on, the display looks normal, and there are no obvious warning lights. However, when you try to print a document, your computer displays a message saying the printer is offline. Restarting the printer may temporarily resolve the problem, but sometimes the offline status returns.
The Canon Printer Offline problem can happen even when the device is turned on and connected to WiFi. This is because a printer's power status and its ability to communicate with a computer are two different things.
If your Canon Printer Says Offline despite being powered on, the issue may involve network communication, incorrect printer settings, outdated connection information, or stuck print jobs. Here are seven possible reasons and the steps you can take to restore printing.
Why Is My Canon Printer Offline When It Is Turned On?
A printer can be powered on without being available to receive print jobs.
Common symptoms include:
The printer's power light is on, but Windows reports it as offline.
The printer is connected to WiFi but does not print.
The computer cannot detect the printer.
Print jobs remain stuck in the queue.
The printer appears offline after waking from sleep mode.
The offline message appears after restarting the router.
Before making changes, check whether the printer displays any error messages and whether its wireless connection is active.
1. The Printer Has Lost Its WiFi Connection
One common reason for a Canon PIXMA Printer Offline message is a disconnected wireless network.
Even if the printer is powered on, it cannot receive network print jobs without a working connection.
Check the printer's WiFi status using its display or network information page.
Confirm that it is connected to the correct wireless network.
If the printer has disconnected, reconnect it using the appropriate wireless setup procedure for your Canon model.
If the connection drops repeatedly, investigate signal strength and router compatibility.
2. The Computer Is Using an Outdated Printer Address
Your wireless router normally assigns an IP address to the printer.
If the printer receives a different address after a router restart, the computer may continue trying to reach the previous one.
This can cause a Canon Printer Offline but Connected to WiFi problem.
Print the printer's network configuration information and identify its current IP address.
Compare it with any manually configured printer address on your computer.
If the saved connection is outdated, update it or add the printer again.
For advanced users, configuring a DHCP reservation on the router may help prevent future address changes.
3. The Printer Is Paused or Set to Offline in Windows
Sometimes, the Canon Printer Showing Offline problem is caused by the computer's print queue rather than the printer itself.
Windows may have a paused queue or an offline printing option enabled.
How to Fix Canon Printer Offline Windows 11
Open Settings.
Select Bluetooth & devices.
Choose Printers & scanners.
Select your Canon printer.
Open the print queue.
Check whether printing is paused or the printer is configured to work offline.
Resume printing or disable the offline option if it is enabled.
The available controls may vary depending on the Windows version and printer driver.
After making changes, print a test page to confirm that the printer responds.
4. Stuck Print Jobs Are Blocking New Documents
A failed print job can prevent additional documents from printing.
Your printer may appear unavailable even though its power and network connections are working.
Open the print queue on your computer.
Look for documents marked as failed, pending, or stuck.
Cancel the affected print jobs and try printing a new document.
If the queue does not respond, restart the printer and computer.
On Windows, restarting the Print Spooler service may help with persistent queue problems.
Avoid deleting system files unless you understand the required troubleshooting procedure.
5. The Printer Is Not Communicating After Sleep Mode
Some Canon printers enter a low-power state when they are inactive.
When the printer wakes, it may take a short time to restore communication with the computer.
If your Canon Printer Keeps Going Offline after being idle, sleep or network standby behavior may be involved.
Wake the printer using its control panel.
Wait briefly and check its network status.
If it remains connected to WiFi but the computer reports it as offline, review the printer's saved connection and operating system settings.
Check whether your model provides configurable network standby options.
6. The Printer Driver or Software Is Not Working Correctly
An outdated, incompatible, or incorrectly configured printer driver can cause communication problems.
This may happen after a Windows or macOS update.
If the printer stopped working after a software change, check whether your installed printer software supports the current operating system.
Fix Canon Printer Offline Mac
Open System Settings.
Select Printers & Scanners.
Choose your Canon printer.
Review its status and print queue.
Resume paused jobs or remove failed documents.
Confirm that the printer is connected to the correct network.
If the printer remains unavailable, consider removing an outdated printer entry and adding it again using a compatible printing method.
Some Canon models support AirPrint, while others may require model-specific software.
7. Router Settings Are Preventing Printer Communication
Your Canon printer may be connected to WiFi but unable to communicate with your laptop or desktop.
This can happen when the printer and computer are connected to isolated networks.
Guest WiFi settings, device isolation, or network restrictions may prevent local printing.
Check whether both devices are connected to networks that permit communication.
If your router has access control features, review whether the printer is restricted.
Avoid disabling router security features unnecessarily.
If the printer works after connecting both devices to the same accessible home network, network isolation may have caused the offline status.
What If Your Canon Printer Still Says Offline?
If the printer remains offline after checking these seven possible causes, try a simple diagnostic test.
First, confirm that the printer can print a built-in test or network information page.
If the printer produces its own test page, the basic printing mechanism is functioning.
Next, verify its network connection and IP address.
If the printer is connected to WiFi but cannot print from your computer, focus on printer discovery, saved connections, and print queue settings.
If the printer cannot print its own test page, investigate any displayed printer errors, paper problems, or ink-related issues.
This approach helps distinguish a communication problem from a printer hardware problem.

Final Thoughts
A Canon Printer Offline message does not necessarily mean the printer is switched off or damaged. Even when the device is powered on, network communication problems and incorrect computer settings can prevent printing.
