Enhanced I/O (EIO) Configuration
This printer comes equipped with two enhanced input/output (EIO)
slots. These slots hold compatible external devices such as the
HP JetDirect print server network cards. Plugging EIO network cards
into the slots increases the number of network interfaces available to
the printer.
EIO network cards can maximize printer performance when you are
printing from a network. In addition, they provide the ability to place
the printer anywhere on a network. This eliminates the need to attach
the printer directly to a server or a workstation and enables you to
place the printer closer to your network users.
The printer control panel will have an additional menu (EIO Menu) if
the printer is configured with EIO network cards.
HP JetDirect Print Servers
HP JetDirect print servers (network cards) can be installed in one of
the printer’s EIO slots. These cards support multiple network
protocols and operating systems. HP JetDirect print servers facilitate
network management by allowing you to connect a printer directly to
your network at any location. HP JetDirect print servers also support
the Simple Network Management Protocol (SNMP), which provides
network managers with remote printer management and
troubleshooting through HP JetAdmin software.
Note Installation of these cards and network configuration should be
performed by a network administrator.
