Where can I find a driver fro Cannon TS9120 for OS 11.4

According to this Apple document, About AirPrint - Apple Support, your printer is AirPrint compatible. It doesn't need drivers if you have a LAN. Get it's user manual and see how to connect it to your LAN.

Then go to System/Printers & Scanners, Control (right) - click on your printer and remove it. Then add it back with AirPrint.

Hi,

As mentioned by Old Toad, Canon TS9120 is a model supporting the driverless AirPrint technology.

If necessary, additional information can be found in a guide from Canon Europe (for similar models):

Canon apparently doesn't have direct support for the OS for that printer. However, open source support may be available if you use a USB printer cable to the printer, turn it on, and go to Apple menu -> System Preferences -> Printer and Scanner and click on the Option key together with the plus symbol below the list of printers.

If the printer is already on WiFi, just make sure your Mac is on the same secure WiFi. Open WiFi's are difficult to setup printers on.
