The first thing I'd do is uninstall and reinstall.
I'm not sure what came down to your PC on 4/17 but Microsoft Updates are
usually released on the 2nd Tuesday of every month, so it would have been
4/15 that they arrived. Are you sure it was a Microsoft Update that you
got?

I deleted the Canon printer, unplugged the USB and opened the Device Driver
and under Printers, deleted the Canon driver.
Then I restarted the computer and reconnected the printer via USB.
Computer found the printer and installed the software.
The printer is working again.
I suspect deleting the driver from the Print driver did the trick.
Uninstalling and reinstalling probably would have been simpler but at this
point, I'm just glad the printer is working again.
Thanks,
Judy
