My Canon MX870 printer keeps showing "communication error" and won't print. Absolutely nothing has changed.

I've been using my Canon MX870 successfully for nearly 2 years. I've done nothing to my computer set-up. I print from my

MAC laptop via Wi-Fi to the printer. No wires are loose or disconnected. It just all of a sudden stopped accepting print jobs. Not always; sometimes it will print just fine. Other times, and most frequently, I get an error message saying "a communication error has occured." NEED HELP!
