Question about Canon PIXMA MX850 Multifunction Printer
Uninstall the Canon driver and Cannon application software. Then it is a good idea to scan the whole system for viruses, malware and spyware as these can affect performance significantly. Next scan the system for un necessary drivers and applications etc. You can do this by using a free 30 day evaluation of Ashampoo from www.ashampoo.de that will check out the whole system and assist in removing all the unwanted junk, make sure that you clean the registry as well. I have been using this software for many years with great success in my workshop in improving system performance on many Windows operating systems. Also then do a full HD defragment - also available in the Ashampoo tool. Then when this is complete download all the applications and the driver from Canon Support.
Then retry the application and printing.
