Network requirements
Before you install the E-42B on the network, it is strongly recommended that you read
“Stages of installation on the network”
on page 9. Step
of installing the E-42B on the
network is to configure your network environment. You must configure network servers to
provide users with access to the E-42B as a network printer.
Network protocols
When the E-42B is connected to a network, it behaves as a networked printer. The E-42B
supports the following network protocols:
• TCP/IP, which also includes the DHCP, FTP, HTTP, IMAP, IPP, IPv4, IPv6, LDAP,
LPD, LPR, NBT, POP3, Port 9100, SMB, SMTP, SNMP, SNTP, and SSL/TLS
protocols
• AppleTalk (for font downloads only), Bonjour
These protocols can run concurrently on the same cable. Computers that use other protocols
can print through a server that uses one of the supported protocols. The E-42B automatically
switches to the correct protocol, and handles all connections simultaneously.
Windows networks
The E-42B requires a valid IP address, subnet mask, and gateway address.
Type these addresses manually or use the DHCP protocol to assign them dynamically. Make
sure the E-42B name and address are listed in a domain name server (DNS) or hosts name
database used by your system.
If more than one E-42B print connection is published (for example, if both the Print queue
and Hold queue are published), consider creating a printer for each print connection, so that
users can print to each connection directly.
Configure the E-42B with the correct Windows domain name.
This is especially important for Windows printing, also known as Server Message Block
(SMB) printing. To use Microsoft Active Directory, you must assign the E-42B to a domain.
If you assign the E-42B to a workgroup, you cannot use Microsoft Active Directory.
AppleTalk networks (only for font download support)
AppleTalk networks support only font downloads if you enable AppleTalk in Configure. To
allow Mac OS X computers to access Bonjour printers, you must enable Bonjour in Setup.
