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!

MacBook Pro (15-inch 2.53 GHz), Mac OS X (10.7.4), Canon PIXMA MX870 printer

Hi Peter,

Yes, that must be my problem. I lost communications completely a few months ago and deleted printer and scanner and then re-added but for some reason on the printer re-appeared. Sound slike I should check Bonjour setting on printer to see if it got disabled. Would that be the only place I need to make sure Bonjour is enabled or do I need to check it on Mac as well? Thanks again for assistance here.

Its only on the printer. You can access the settings either through the printer's own screen or through its web page.

Hello peterfromtotnes,

Turns out Bonjour has been enabled on my printer. Any other ideas. Still only getting the printer to appear in the "Print and Scan" utility.

Thanks,

epie

Finally solved this problem by unplugging and replugging in the printer. Things were fine for awhile, now they've started acting up again. So I'm going to try the plug again.....

This was perfect! Thank you! The only thing I found was that I had to turn my printer off and then on again in order for it to work.

I followed pfava's instructions and it's working well so far. I'll update with any problems if it disconnects again over the next few days.
