Lexmark periodically releases new firmware versions (e.g., from base version LW51.PR.P331 to LW51.PR.P523 ) that address three primary areas: security vulnerabilities, functional bugs, and feature enhancements. For example, a firmware update might patch a vulnerability in the printer’s embedded web server that could otherwise allow unauthorized access via port 443 (HTTPS).
