In response to your reply to Beckie Marsh on Mar 7:
1 & 2. My wireless networked printer would not print anything yesterday. It had been several days since I last used it. When I checked the printer queue, the document gets spooled, and status switches to printing momentarily. But, nothing reaches the printer. Then the queue clears. Checking the Device Manager shows a yellow triangular flag. Checking the device driver shows a device status message "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"
3. Added some new add-ons to Firefox v11.
4. I assume the printer queue uses this device to transfer data to the wireless printer.
I have been trying Microsoft, Intel and Dell Support sites to find a fix. I have uninstalled and reinstalled the device three times at the suggestion of the troubleshooting processes at each support site. Same result each time. As Ms. Marsh wrote ............HELP
