A CA certificate tells Jetdirect which identity certificates should be trusted (i.e. must be signed by that

CA) when Jetdirect is receiving a certificate from another entity. Once a CA certificate is installed,

any identity certificates signed by that certificate authority can be trusted.

Installing CA certificates is a much simpler process than installing identity certificates. A CA

certificate is merely exported from the CA server itself, then imported into Security Manager to be

installed on the fleet. Since the CA certificate is not unique per device, other tools such as HP Web

Jetadmin could also install the CA certificate on the fleet. However, Security Manager expands the

functionality by supporting multiple CA certificates per device.

The Jetdirect CA certificate has traditionally been located under the Networking tab in the same place

as the identity certificate.

Devices also support other types of CA certificates under the Security tab. When the device connects

securely to a server such as LDAP or SMTP, these CA certificates under the Security tab are used to

authenticate the authenticity of the server so that data is not exchanged with an imposter.

Newer HP devices such as the HP LaserJet M604/605/606, HP Color LaserJet MFP M577, HP Color

LaserJet M552, and others began to unify the location of CA certificates previously located in these

two separate places under EWS. Both the Jetdirect and device CA certificates have been combined

to be located under the Security tab.
