DHCP
Dynamic Host Configuration Protocol (DHCP) provides a more flexible
dynamic IP address assignment than BOOTP. DHCP requests are
broadcast via UDP port 67, and responses listened for on UDP port 68.
When DHCP is enabled it will cause a slight delay at turn-on
(configurable via the “VARIABLES ETHERNET DHCP_OFFERS”
command) as the printer gets offers of IP addresses and decides which
to use. The printer will request the following DHCP options:
OPTION Name Notes
1 Subnet Mask required
3 Router required
67 Boot file name optional
Printer Configuration
The printer supports several print methods. Select the print method
appropriate for your application.
In most cases, LPD is the recommended method. The printer appears
as a remote host with a remote print queue when using this method.
An alternate method is via a direct socket connection using RTEL in
the printer. Using this method, all data sent is dumped directly into
the printer's text buffer. This approach may be appropriate when
developing an application in C or another high level language that can
make direct socket calls.
Configuration Options
You must configure the printer for your network environment before
using it. Your network administrator should be involved in the
process.
If your network supports the DHCP protocol, you may enable DHCP,
then cycle power on the printer with the Ethernet cable plugged in and
the printer will automatically setup by the DHCP server on the
network. If DHCP is disabled, you must select and set the printers’ IP
address, Subnet Mask and Gateway IP address. You may also set the
default Server address if FTP or TFTP transfers will be made to the
printer.
