is a network security system that monitors and controls the incoming and outgoing network traffic

based on predetermined security rules. HP PageWide printers provide this feature to ensure that printing is

secure.

Figure 37: The Firewall Setup options

The

Failsafe

option (Figure 38) ensures that HTTPS remains accessible even if it is blocked by the Firewall

policy. This allows the administrator to test the policy without inadvertently locking themselves out of the

device. It is recommended that the Failsafe Option be disabled once the policy has been successfully tested.
