Description
T146 -- Buffer packing. HP proprietary. Set buffer packing for TCP/IP packets.

T149 -- Interlock mode. HP proprietary. Require an acknowledgement (ACK) on all TCP packets
before allowing the printer to close a port 9100 print connection. Specify a port number
and option, as in the following example:
<Port Number> <Option>
<Port Number> : For supported HP Jetdirect print servers, the default port number is 1.
<Option> : Set to 0 (default) to disable interlock, or 1 to enable.
For example, setting this to “1 1” specifies port number 1 and enables interlock.
T150 -- TFTP server's IP address. HP proprietary. Specify the IP address of the TFTP server
where the TFTP configuration file is located.
T151 -- Network configuration. HP proprietary. Send either BOOTP-ONLY or DHCP-ONLY
requests.
TFTP configuration file entries (IPv4)
To provide additional configuration parameters for your HP Jetdirect print server, such as SNMP or
non-default settings, you can download a configuration file 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. The following is an example of a TFTP configuration
file. (The # symbol signifies a remark and is not included in the file.)
