I cannot print from Firefox, keep getting "an unknown error occurred while printing."

Whenever I attempt to print something from Firefox (email, receipt, and so on), printing fails and I get the message "an unknown error occurred while printing." Printing from Internet Explorer works without any problem.

Am having the same problem, and we've tried the reset and tried fully uninstalling FF and files and reinstalling, same problem. Prints from from IE, Chrome.....what else? I see alot of other people out on the web having the same issue. Window 7 64-bit, Firefox 3.6.15 (was 3.6.14), HP color laser printer.

Yes, I've read that the reset only works for a brief time after which the problem recurs. So far I'm still able to print but I don't expect that to last. I'd hate to have to open IE every time I want to print something.

I reset my firefox preference as directed & it worked. It had the wrong value under print.print_printer
