Canon pixma ts8150 offline since ventura 13.4 update

• Some users have reported similar issues with their printers after updating to ventura 13.4. One suggested workaround is to reset the printing system on your Mac and then add the printer again. To do this, you need to go to System Preferences > Printers & Scanners > Control-click anywhere in the list of devices > Reset printing system. Then, you can try to add your printer again and see if it works.

Hi,

This is a user-to-user forum, so (with the occasional exception of a Community Specialist) do not expect any technical input from Apple here. If necessary, you may have to contact Apple Support directly, or Canon.

It would probably be correct to assume that the USB cable has been disconnected when attempting to use the printer via Wi-Fi.

If all Wi-Fi settings are OK, you may want to (again) try a full power-cycle sequence (including the router), in this order, with these waiting times: Power off the Wi-Fi router, the Canon 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 Canon printer. Wait a minute or two. Power on the Mac. Finally, power on all other devices/computers.

You could also use an iPhone or iPad in order to check that wireless AirPrint printing (that is, without a special iOS/iPadOS app) works via the Wi-Fi router.

By the way, have you checked whether your printer has the latest firmware?

Thank you for your report. You're welcome! Glad to hear that it is working. Yes, sometimes electric current moves in mysterious ways.
