A personal software firewall is blocking communication between the printer
and the computer
The personal software firewall is a security program that protects a computer from
intrusion. However, the personal firewall might block communication between the
computer and the printer.
If you cannot communicate with the printer, try disabling the personal firewall. If you
are still unable to communicate with the printer, then re-enable the firewall.
If disabling the firewall allows you to communicate with the printer, you might want
to assign the printer a static IP address and then re-enable the firewall. To assign
the printer a static IP address, see the network guide that came with the printer.
