Currently on OS X 10.11.6, iMac 27" mid-2011, but from mid-2015 have experienced slower and slower transfer of data to, and the required printing on both of my Canon printers, MP640 (A4), and iX4000 (A3), since up dating their respective firmware.
I have sought advice from Canon, but response there was none.
Any suggestions (like how can I trace and delete the new firmware??? if relevant) from the Mac end will be TOTALLY appreciated.
In anticipation and hope, many thanks.
