I have an imac but no cd drive. How do I hook up my printer?

You can download the drivers directly from the Canon (United States) website, my friend.

I'm afraid you'll need to select which specific version of Mac OS that you're using on your computer from the drop down boxes.

Theres three approaches first which you can are attempting connecting your printer via usb and doing it that method, or you could buy an apple super power for eighty bucks that plugs into your imac and its a disc force and finally you should be ready to go online and in finding the program on the canon website and down load it

now a days devices have been made wisely so if u purchased a new printer i think while u plug the printer with ur computer the drivers are auto loaded into ur machine. If no u can download from internet.
