A free firmware upgrade allowed the 610n EIO print server, shipped in 2000, the same capability. Suddenly, a few million HP Jetdirect EIO cards had SSL/TLS capability. Why? The answer was secure management. HP printing and imaging devices were becoming more complex and more feature oriented. They were becoming valuable assets to a company's infrastructure. Having the ability to use a browser to manage a device using HTTP was one thing, using the same browser and using HTTPS to manage it securely was a great benefit. Unfortunately, many users of HTTPS are under a false sense of security because they have not deployed SSL/TLS 1
