We had 9500II and now we have Pro-100 and Pro-1. All are excellent ink jets. We use LR on our Macs that run Mavericks. We do the editing, go to the print module, select the printer, select the ICC profile for the paper we want to use, set the image size...etc. and hit print.
What do you mean by maximum print setting or best setting? If you use the ICC profile for the paper you are using, what more do you want to do via the printer?
BTW never use the drivers and software on the printer CDs. Download the latest from the Canon site. The only thing I used was the driver and the Canon network tool as I hook the printers up via ethernet, not USB.
