I can't get Win10 build 10049 to install my Canon Pro9000 Inkjet printer. It is connected by USB and when I turn it on, an icon appears in the taskbar briefly and then disappears. Devices show Inkjet printer but no drivers available. I downloaded latest driver from Canon site and tried again following their instructions. No joy! My Lexmark 250dn installed automatically and so did my Canoscan 8800F as well as my Canon MP490 with no problems. Help please. I have also tried compatibility mode using Win8.1 and Win7Pro.
