So I follow the link to the Canon website, and I'm directed to this page. which shows that this printer needs driver 10.30.3.0, but there are no links on this page to show me where I might find this version. Software update had no mention of any Canon drivers, it just wanted to update iTunes.

Try deleting the /Library/Printers/Canon folder, connecting the printer and turning it on, then using Software Update to install the updated Canon drivers. So now is Apple trying to be like this? We pay more for Apple products and we expect them to work without all this hassle. Come on, did anyone test out this combination before they decided to sell it? I know that Microsoft has a 90% market share with this kind of approach. I don't know what they were thinking when bundling this printer with an iMac if there is not even a driver that works with it. Now I know the USB cable is just fine because after all this annoyance, we hooked up the old Epson printer, and it worked just fine, as we have come to expect with Apple products. I even try to connect this printer to the old iMac, running OS 10.4 on it, and that does not work either. I spend hours looking all over the place for this driver, and do not find it. I find some info that says that I should use the 10.26.1 driver, but The website has a driver - versionġ0.26.0 which does not work. Have had problems with using this printer with Snow Leopard. So I go and google for the information and find out that there have been a lot of other people who I turn it off and on, restart the computer, and nothing works. We download and install the drivers and attempt to add the printer through system preferences. Sure that OS has only been out for a year, so we'll go and download it. So we're told to get the latest drivers from the Canon website, because the files on the CD are not compatible with Snow Leopard. This printer - the Canon PIXMA MP490 Photo All-in-One Printer, which was part of a bundled package via the Apple on-line store, with a rebate. We migrated everything from the old iMac via FireWire and Migration Assistant, so it all seemed to be fine. We got a new iMac set up and installed today.
