MX870 driver misbehavior: any solutions?


I have an MX870 printer. The printer itself is great, but the Windows driver is so badly behaved that it makes the printer very difficult to use. I'm posting to ask if anyone knows how to get it under control.

The problem is that the driver gets installed in triplicate, so I have "Canon MX870 series printer," "Canon... printer (Copy 1)," and "Canon... printer (Copy 2)." Only one of them works, and which one works is liable to change if the environment changes, for example, if the printer is detached and reattached. Then I have to play a game of find-the-real-driver before I can print again. If I guess wrong and open the Properties dialog, the dialog is disabled and can't be opened again until I reboot.


I installed the latest driver today to see if it would fix the problem. It had no effect at all.

I've lived with this for a couple of years, but I'm now detaching my laptop computer to take with me on a regular basis, and I have to play find-the-real-driver several times a week. I can't afford the time it takes. If I can't make the driver behave I'm going to have to replace the printer.

I'm sorry it has taken me so long to reply. My time is heavily committed, and it is difficult for me to fit in unscheduled activities like solving problems of this nature.


I need to explain something that seemed superfluous when I first posted, but now is significant. I gave you the impression that I have this problem on one computer. In fact, I have it on two. One is my personal computer; the other is a laptop issued to me at work. I installed the driver on these machines over a year apart. They have nothing in common except that they both run varieties of Windows 7.


Since installing the driver on my work computer yielded exactly the same problem as installing it on my personal computer, I see no reason to expect that uninstalling and reinstalling it on either machine would produce a different result. I can't justify taking the time to do this if it will not yield either a solution or useful information.


If you can offer a plausible reason why I should hope for a different result if I uninstall and reinstall, I'll do it. Otherwise, I must ask you to try again.
