Option

 

 

 

 

T146

--

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

 

 

0 (default): Pack normal data buffers before sending to the printer.

 

 

1: Disable buffer packing. Data is sent to the printer when received.

 

 

 

T147

--

Write mode. HP proprietary. Set the TCP PSH flag for device-to-client data transfers.

 

 

0 (default): Disable.

 

 

1: Set the TCP PSH (all-push) in all data packets.

 

 

 

T148

--

IP gateway disable. HP proprietary. Control configuration of a Gateway IP address.

 

 

0 (default): Allow configuration of an IP address.

 

 

1: Prevent configuration.

 

 

 

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.)
