Canon MP520 printer does not have a driver
My Canon PIXMA MP250 printer is not finding a relevant driver. It used to work with Mountain Lion I'm now running Sierra 10.12.6).
I tried downloading - MP520 series Printer Driver Ver. 6.9.3 (Mac OS X 10.2/10.3/10.4/10.5) from the canon website but the iMac does not seem to register it. Neither can I point to it as I don't know where it has been installed in the filing system (I tried library, printers and System, library, extentions).
iMac, macOS Sierra (10.12.6)
