My firewall is blocking my HP Envy 5530 from being found on the network — what should I do?

Security software such as firewalls can block communication between your computer and printer when installed over a network. Temporarily disable your firewall to check if that resolves the issue, and if the printer is then found, adjust your firewall settings accordingly.
