dynamic RAM The memory devices used to store the label formats in electronic form while
they are being printed. The amount of DRAM memory available in the printer determines the
maximum size and number of label formats that can be printed. This is volatile memory that
loses the stored information when power is turned off.
Extensible Authentication Protocol over Flexible Authentication via Secure
Tunneling (EAP-FAST) Extensible Authentication Protocol-Flexible Authentication via
Secure Tunneling (EAP-FAST) is a publicly accessible IEEE 802.1X EAP type developed by
Cisco Systems. It is available as an IETF informational draft. Extensible Authentication
Protocol-Flexible Authentication via Secure Tunneling (EAP-FAST) is a publicly accessible
IEEE 802.1X EAP type developed by Cisco Systems. It is available as an IETF informational
draft. Cisco developed EAP-FAST to support customers who cannot enforce a strong
password policy and wish to deploy an 802.1X EAP type that does not require digital
certificates, supports a variety of user and password database types, supports password
expiration and change, and is flexible, easy to deploy, and easy to manage. For example, a
customer using Cisco LEAP who cannot enforce a strong password policy and does not want
to use certificates can migrate to EAP-FAST for protection from dictionary attacks.
Extensible Authentication Protocol
over Transport Layer Security (EAP-TLS) Second generation Wi-Fi security. Current
Wi-Fi security standards (802.1x) define the use of the TLS protocol encapsulated within the
Extensible Authentication Protocol (EAP) as one of the strongest security mechanisms for
Wi-Fi. Using EAP-TLS provides well-regarded, standards-based security between an access
point and a Wi-Fi client. This is a Microsoft standard.
• A form of 802.1X (EAP) authentication
• Uses client and server certificates for mutual authentication (PKI)
• TLS 1.0 (Transport Layer Security) is based on Secure Socket Layer (SSL) 3.0
Extensible Authentication Protocol
over Tunneled Transport Layer Security (EAP-TTLS) EAP-TTLS is an extension of
EAP-TLS which provides for certificate-based, mutual authentication of the client and
network. Unlike EAP-TLS, however, EAP-TTLS requires only server-side certificates,
eliminating the need to configure certificates for each WLAN client. In addition, it supports
legacy password protocols, so you can deploy it against your existing authentication system
(such as tokens or Active Directories.) It securely tunnels client authentication within TLS
records, ensuring that the user remains anonymous to eavesdroppers on the wireless link and
the entire network to the RADIUS server.
firmware This is the term used to specify the printer’s operating program. This program is
downloaded to the printer from a host computer and stored in FLASH memory. Each time the
printer power is turned on, this operating program starts. This program controls when to feed
the media forward or backward and when to print a dot on the label stock.
FLASH memory FLASH memory is non-volatile and maintains the stored information
intact when power is off. This memory area is used to store the printer’s operating program. In
addition, this memory can be used to store optional printer fonts, graphic formats, and
complete label formats.
Font A complete set of alphanumeric characters in one style of type. Examples include
CG Times™, CG Triumvirate Bold Condensed™.
