Just recently got a new iMac at work (upgraded from a 2006 model) and am having difficulties adding our Canon ImagePrograf 9000 and 9000s to it. When I use the add/remove printers utility in system preferences it says that the software isn't available from Apple and to contact your manufacturer. I have gone to Canon's website and the only stuff they have is for OS X 8. I install it but still get the same error. Weird thing is that our 2006 iMac had Mavericks as well and had both these printers running just fine. Any suggestions?
