Ever since I installed OS X Lion, I've been having problems printing with my Canon Pixma 860. Sometimesw it works just fine. Other times, I get a "communication error." I downloaded the latest drivers from Canon, I have deleted and reinstalled the printer in my system preferences, and I've disconnected and replugged in the printer. Sometimes these actions work, sometimes they don't. It will print one or two documents just fine, and then when I try to print the next document moments later, I get a communication error. I use the printer wirelessly; I tried connecting a USB cable, but it didn't help. My husband, who is using Snow Leopard on his iMac and also connects to the printer wirelessly, is having the same exact problems from his computer. It's driving me nuts. Is anyone else having the same problem? Is there a fix, other than buying a new printer?
