Printer driver

Please could someone help finding a link to the latest driver for my Canon Pixma MX885 all in one, I've gone to Canon site but don't really understand all that is there.
I'm running win7 64bit.
I just want to update driver as I have a problem with word 2007 and seems related to printer, both companies claim it's the others cause.
Just like to try and eliminate one.
