Just bought new ZT computer with Win 7+SP1 with IE8 and have major problems syncing up programs and hardware; in this case my Canon Pixma 860 injet won't print; it is hard wired to the computer now (USB cable) but I get the error message in Title of post after running the "Fix It" diagnostic.
What is the error message you receive?
Have you installed the printer drivers, yet?
Download the windows 7 drivers from here:
Why can't I print?
Run the "fix it" and also other manual steps.
That did the trick! I thought the CD would have been sufficient, but these addl updates were exactly what I needed.
Thanks for the help!
