Hi,
I have El Capitan.
I figured it out with a simple step.
But I went through an unpleasant process to get there.
In desperation, I googled "Canon printer technical support", and where normally I am very careful about listings that come up, a site called something like, "Canon USA technical support" came up with a toll free (844) (already weird!) area code. I called, I think I was talking to India, and when I asked about the company he told me Canon contracts out to and authorizes other companies for third party technical support. he asked if he could share my computer screen and since I believed I was talking to Canon, I said yes and he swooped in, scrambled through my computer at high velocity, told me what a mess it is, told me I had to buy this "Anti-Threat" software, asked me if I do onine banking and shopping to which I answered in the affirmative (obviously still believing I was talking to Canon even though I felt uncomfortable with what he was doing), he opened up the Walmart website, showed me the software to buy that was $1,200 to buy, then told me I could buy it online elsewhere for $249, and then told me that he could help me with my printing issue for $149. I paid him nothing and hung up.
The next day I called the Canon website and "Roy" at technical support assured me that Canon does not contract out to 3rd party technical support, he told me to download another driver, and VOILÀ!, everything is perfect now.
Thank you for wanting to help me figure it out!
