After upgrading to macOS 15.3 my Canon Pixma G7020 no longer works on my MacBook Pro network

The Canon G7020 is listed as a supported model in About AirPrint – Apple Support (UK) (en-gb edition, March 19, 2025). This means that it should work with the latest macOS versions without the need for additional printer drivers when connected to the same network (Wi-Fi router) as a Mac computer. Printing should also be possible from an iPhone/iPad without extra apps.

AirPrint works with wireless (Wi-Fi) or wired (Ethernet) network connections, so you could choose to connect the printer wirelessly or use an Ethernet cable to one of the LAN ports of the Wi-Fi router. An Ethernet printer connection may be more stable.

Any change if you try a full power-cycle sequence (do not forget the router)?

• Power off the Wi-Fi router, the printer, the Mac, and all other devices/computers.
• Wait two to three minutes.
• Power on the router.
• Wait two to three minutes.
• Power on the printer.
• Wait a minute or two.
• Power on the Mac and all other devices/computers.

Yeah, you're not alone—macOS 15.3 seems to be breaking network printing for some Canon models like the G7020. Try deleting the printer, resetting the printing system (in System Settings > Printers), then re-adding it; if that doesn't work, check Canon’s site for updated drivers.
