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
