Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

 

pre installed windows.

Hi my mates laptop a Toshiba Satellite L500-1DT won't boot into windows and I was going to reset it back to factory settings, when I set the laptop to boot from hard drive in the bios nothing happens and when windows tried to repair it I got the message ( Media test failure) but when I tried to put a fresh install of windows using my disc I got to the part where you wipe it and it showed three partitions one was SYSTEM and the other was Windows would the pre installed windows be in one of them if so how do I get to it, help, I think my mate had a muck about with it but he is not saying.
