I've installed the drivers for it and it was working a few weeks ago... now it has stopped working an the computer runs like crap because of this mpservic.exe that is running 99% of the resources which is in the canon folder. I've tried uninstalling... completely deleting the whole folder and then reinstalling it and it's still at 99% which is causing the computer to run very slow and the printer still doesn't work. I've also tried making the mpservic.exe manual instead of automatic and the printer won't work still... any ideas?
