Canon Pixma MP520 and El Capitan

I just upgraded to Mac OS El Capitan (10.11.5) on my iMac (27-inch, Mid 2010) but am now having trouble printing to my Canon Pixma MP520.

I tried to research possible solutions including deleting CUPS files from the Library/Printers/Canon folder. And re-installing drivers, etc. I've deleted and re-added the printer. All to no avail.

Any thoughts?

Here is the error message I receive:
