“Canon printer offline” can describe two different failures: the printer has disappeared from the network, or Windows is sending jobs to the wrong queue. Reinstalling the driver before separating those cases often adds a duplicate printer and makes the status more confusing. Start with one test page, one connection path, and the printer’s current network information.
First decide: printer, network, or queue
Place a sheet on the scanner and make a local copy, or print a nozzle check from the printer panel if your model supports it. A successful local page does not prove Wi-Fi is healthy, but it separates ink, paper, and print-engine faults from computer communication. If the printer itself shows an error code, solve that code before chasing an offline label.
| What you observe | Most useful next test | Likely layer |
|---|---|---|
| Local copy also fails | Read the code or warning on the printer | Printer, paper, ink, or hardware |
| Copy works; every computer is offline | Check printer Wi-Fi and IP address | Router or printer network |
| Copy works; one PC is offline | Inspect that PC’s queue and port | Windows queue or driver |
| Some jobs print, one remains stuck | Cancel that job and restart Spooler | Document or print queue |
Confirm the same Wi-Fi before touching the driver
Canon’s network manual tells users to verify power, router status, wireless LAN, and matching network settings. Compare the SSID shown or printed by the printer with the SSID used by the computer. Guest Wi-Fi, an extender with a separate network name, or a recently replaced router can leave the printer connected to an old network even though its wireless icon is lit.
Print the network settings from the model’s menu and note the IPv4 address. Do not publish the sheet because it may contain network details. If the address is blank or begins with 169.254, the printer has not received a normal address from the router. Reconnect it using the setup procedure for the exact PIXMA, MAXIFY, imageCLASS, or other Canon model.
Use the IP address as the dividing line
Enter the printer’s IP address in a browser on the same network. Some models expose a Remote UI page; others may not. You can also use Canon IJ Network Device Setup Utility where supported. If the utility sees the printer at the current address, the Wi-Fi path exists and the stale Windows queue becomes the stronger suspect. If no device can reach it, stay with router, SSID, signal, and address assignment.
A printer that works for a few days and then becomes offline may be receiving a different IP address. Do not invent a static address inside the printer without checking the router’s DHCP range. A router reservation for the printer’s current MAC address is usually easier to manage, but follow the router maker’s instructions.
Choose the real queue, not the duplicate
Open Settings > Bluetooth & devices > Printers & scanners, select the Canon printer, and open its queue. If Windows lists the same model twice, compare which entry can print a test page. Keep the working instance as default and remove only the proven stale duplicate. A queue labeled with an old network or WSD path can remain after a router change.
| Queue evidence | Action | What not to do yet |
|---|---|---|
| Pause Printing is enabled | Clear Pause Printing | Do not reinstall the driver |
| Use Printer Offline is enabled | Clear the option and retry | Do not reset the router |
| One corrupt job will not leave | Cancel it, then restart Print Spooler | Do not delete every printer |
| Queue points to an old IP | Add the printer at its current address | Do not force an address outside DHCP |
Clear a stuck job in a controlled order
- Cancel all jobs from the Canon queue and wait one minute.
- Turn the printer off, wait 30 seconds, and turn it on.
- In Windows Services, restart Print Spooler.
- Print a Windows test page before reopening the original document.
- If the test page works, export or recreate the problem document instead of changing the network.
Microsoft’s current offline-printer guidance follows the same progression: power cycle, verify the same Wi-Fi, set the correct default printer, clear offline or paused status, restart the queue service, then remove and reinstall if necessary. This order preserves evidence about which layer failed.
When a driver reinstall is justified
Download software only from Canon’s support page for the exact model and operating system. Reinstall when the printer is reachable on the network but Windows cannot create a working queue, when the driver is explicitly unavailable, or after an operating-system change. For a broader Windows driver diagnosis, use our Printer Driver Unavailable and Spooler guide.
An ink or cartridge code is a separate branch. For example, Canon E13 or E16 concerns ink detection, while Canon 5B00 concerns the waste-ink system. Neither is fixed by changing Wi-Fi.
Escalate with useful evidence
Contact Canon or your network administrator when the printer cannot obtain an IP address on a known working SSID, disappears from every device, or repeatedly drops beside the router. Record the exact model, operating system, connection type, SSID name without its password, printer IP, whether a local copy works, and whether another device can print. Never share the network password or a full network-settings sheet publicly.

Frequently asked questions
Why is my Canon printer offline when Wi-Fi is on?
The wireless light can be on while the printer is connected to a different SSID or Windows is using an old queue. Compare the SSID and current IP first.
Should I reinstall Canon software first?
No. Confirm local printing, network reachability, and the correct queue first; reinstall only when those tests point to the driver.
Will resetting the router fix it?
A reboot may renew a connection, but a factory reset changes network settings and can disconnect every device. It is not an early troubleshooting step.
