A technician needs to harden all newly deployed network printers following a data breach. Which of the following should the technician do to BEST fulfill this need?

Installing the most recent drivers primarily ensures compatibility and functionality with client operating systems, but it does not directly harden the printer's own internal security.

Disabling wireless printing might remove one potential attack vector if not needed, but it's a specific configuration change, whereas firmware updates provide broader, systemic security improvements.

Placing all printers on a separate print server can centralize management and isolate printers, but it doesn't directly harden the security of the individual printer devices themselves.

Updating to the latest firmware is a critical security measure for any network-connected device, including printers. Firmware updates often include patches for known vulnerabilities, security enhancements, and bug fixes that harden the device against attacks, which is essential after a data breach.
