Solution 3: Restore the software for your Canon printer
Driver faults are most likely to blame for Canon printer offline troubles. Although the methods outlined above should address the issue, if they do not, you should reinstall your Canon printer driver.
To launch a Run box on your keyboard, press the Windows key and the R key simultaneously.
In the box, type devmgmt.msc and click OK.
Select your Canon printer driver from the Print queues list.
After that, right-click it and choose Uninstall device.
Download and install the most recent driver for your printer model from Canon’s official website.
Then download it and install it on your PC.
While downloading the driver from the Canon website is simple, it may take some time.
If you lack the time, patience, or technical ability to manually locate and download drivers, you must contact the Canon helpdesk immediately to resolve the issue.
Driver Easy will automatically identify your system and download the necessary drivers.
There is no need to know the specific operating system on your computer, you eliminate the danger of downloading and installing the incorrect driver, and you never have to worry about making a mistake during installation.
