Check the print queue
A print job might be stuck in the print queue. To fix, open the print queue, cancel the
printing of all documents in the queue, and then reboot the computer. After the
computer reboots, try printing again. See your operating system help for information
on opening the print queue and canceling print jobs.

Troubleshooting tips and resources .
Check the device software installation
If the device is turned off when printing, an alert message should appear on your
computer screen; otherwise, the device software might not be installed correctly. To
resolve this, uninstall the software completely, and then reinstall the device software.
For more information, see
Uninstall and reinstall the software .
Check the cable connections
Make sure both ends of the USB cable are secure.
Check any personal firewall software installed on the computer
The personal software firewall is a security program that protects a computer from
intrusion. However, the firewall might block communication between the computer and
the device. If there is a problem communicating with the device, try temporarily
disabling the firewall. If the problem persists, the firewall is not the source of the
communication problem. Re-enable the firewall.
If disabling the firewall allows you to communicate with the device, you might want to
assign a static IP address to the device and re-enable the firewall.
Check the wireless connection
Printing larger files using a Bluetooth wireless connection can sometimes cause the
print job to fail. Try printing a smaller file. For more information, see
Problems setting
up 802.11 or Bluetooth wireless communication .
