U• USBSerial interface designed to enable you to "hot-swap" devices, i.e., by plugging and unplugging themwithout turning off the power.W• WEP/WEP KeyAn encryption method employed by IEEE 802.11. Shared security key used to encrypt and decryptdata sent over wireless networks. This printer supports key length of 64 bits or 128 bits, key format ofASCII code or Hexadecimal, and key number of 1 to 4.• Wi-FiInternational association that certifies interoperability of wireless LAN products based on the IEEE802.11 specification.This machine is a Wi-Fi authorized product.• Wireless LANA network that, instead of being connected by physical wires, is connected by a wireless technology,such as Wi-Fi.• WPASecurity framework announced by the Wi-Fi Alliance in October 2002. The security has beenstrengthened more than WEP.◦ AuthenticationWPA defines the following authentication methods: WPA Personal that can be used without anauthentication server, plus WPA Enterprise that do require an authentication server.This machine supports WPA Personal.◦ PassphraseThis encrypted key is used to perform WPA Personal authentication.The passphrase should be a string of 8 to 63 alphanumeric characters or a 64-digit hexadecimalvalue.• WPA2Security framework released by the Wi-Fi Alliance in September 2004 as a later version of WPA.Provides a stronger encryption mechanism through Advanced Encryption Standard (AES).◦ AuthenticationWPA2 defines the following authentication methods: WPA2 Personal that can be used without anauthentication server, plus WPA2 Enterprise that do require an authentication server.This machine supports WPA2 Personal.◦ PassphraseThis encrypted key is used to perform WPA2 Personal authentication.The passphrase should be a string of 8 to 63 alphanumeric characters or a 64-digit hexadecimalvalue.249
