I'm having some issues with my Canon Pixma IP1900 printer – it doesn't respond to any OS requests. I am using Windows 7 x64 with additional Canon drivers and the printer used to work ok, but recently it doesn't anymore.
I've connected it to a second PC running on Win7 x86 and no additional Canon drivers and the printer worked again – not only did Windows find appropriate drivers all by itself, but everything else did work like a charm as well.
Now I assume that the problem is either the drivers (messed up by OS) or the OS itself. My idea is to completely remove Canon drivers and any data associated with the printer. How do I do it?
