b. If you are using a network cable to connect to the network, make sure that the product
name listed on the Ports tab matches the product name on the product configuration page.

c. If you are using a USB cable and are connecting to a wireless network, make sure that the
box is checked next to Virtual printer port for USB.

5. If you are using a personal firewall system on the computer, it might be blocking communication
with the product. Try temporarily disabling the firewall to see if it is the source of the problem.

6. If your computer or the product is connected to a wireless network, low signal quality or
interference might be delaying print jobs.

The product prints slowly
