A colon (:) indicates the end of a field, and a backslash (\) indicates that the entry is continued on the
next line. Spaces are not allowed between the characters on a line. Names, such as host names, must
begin with a letter and can contain only letters, numbers, periods (for domain names only), or hyphens.
The underline character (_) is not allowed. Refer to your system documentation or online help for more
information.
TFTP Configuration File Entries (IPv4)
To provide additional configuration parameters for your HP Jetdirect print server, such as SNMP (Simple
Network Management Protocol) or non-default settings, an additional configuration file can be
downloaded using TFTP. This TFTP configuration file's relative path name is specified in the BOOTP
reply using the /etc/bootptab file's T144 vendor-specific tag (or the "ef" standard BOOTP tag) entry.
An example of a TFTP configuration file is provided below (the symbol '#' denotes a remark and is not
included in the file).

RFC 2132 Description
Option
NOTE:
tag (ef) to specify the relative path name of the TFTP configuration file.
-- Idle Timeout option. An HP-proprietary tag to set the idle timeout (seconds), which is the
amount of time that a print data connection may remain idle before being closed. The range
is 1–3600 seconds.
-- Buffer Packing option. An HP-proprietary tag to set buffer packing for TCP/IP packets.
0 (default): Normal data buffers are packed before sending to the printer.
1: Disable buffer packing. Data is sent to the printer when received.
-- Write Mode option. An HP-proprietary tag that controls the TCP PSH flag setting for device-
to-client data transfers.
0 (default): disables this option, flag not set.
1: all-push option. The push bit is set in all data packets.
-- IP Gateway Disable option. An HP-proprietary tag to prevent configuration of a Gateway IP
address.
0 (default): allows an IP address.
1: prevents a Gateway IP address to be configured.
-- Interlock Mode option. An HP-proprietary tag that specifies whether an acknowledgement
(ACK) on all TCP packets is required before the printer is allowed to close a Port 9100 print
connection. A Port Number and Option value are specified, in the form:
<Port Number> <Option>
<Port Number>: For supported HP Jetdirect print servers, the Port Number is 1 (default).
<Option>: Option value 0 (default) disables interlock, 1 enables.
Example: 1 1 specifies <Port 1>, <interlock enabled>
-- TFTP server's IP address option. An HP-proprietary tag to specify the TFTP server's IP
address where the TFTP configuration file is located.
-- Network Configuration option. An HP-proprietary tag to specify either "BOOTP-ONLY" or
"DHCP-ONLY" requests be sent.
Standard BOOTP option 18 (extensions file path) also allows a standard
IPv4 Configuration 27
