The HP Envy 4500 wireless driver should be used when setting up the printer to be used on a wireless network. The driver is required to enable communication between the printer and the computer, allowing the printer to receive print jobs wirelessly. The wireless driver may also need to be updated periodically to ensure compatibility with the computer's operating system and to address any bugs or security vulnerabilities.
