DESCRIPTION
Hpnpf is a specialized TCP driver for driving network printers. A
network printer is a printer attached to the local area network via its
JetDirect interface or JetDirect EX interface.
Hpnpf is capable of handling bi-directional communications. It accepts
input from either file(s) or standard input. If the file(s) is supplied,
it reads each file in sequence, sends it to a network printer over a TCP
connection. If no input file is given, or if the argument - is
encountered, hpnpf reads from the standard input, enabling hpnpf to work
with other programs. Hpnpf also handles the information coming back from
the printer. Depending on the specified options (see below), hpnpf may
pass all the information to standard output, or filter out the PJL data.
If hpnpf fails to make a connection to peripheral, the connection is
retried until a successful connection is made unless -R is specified.
Options
-Pprintername
printername is the name under which the System V R3 spooler
recognizes the printer, as given on the lp command line. Used to
update the Impressario POD status data base for the printer.
-a type
Indicate that the printer is a PJL (Printer Job Language) based
printer. The type identifies the type of network interface: 1 for HP
JetDirect interface, 3 for HP JetDirect EX interface.
-j jobid+userid
Provide job id and user id to hpnpf. Both are used status messages.
-l logfile
Write verbose logging information to logfile. The logging messages
are details about what hpnpf is doing. It is mainly for debugging
use. If the specified log file is not writable, no logging is
performed.

hpnpf(1) Impressario hpnpf(1)-n Send the PCL escape sequence (ESC&k2G) before the files. This sets
the end-of-line character to be newline (ASCII LF) instead of
carriage-return/line-feed.
-N Translate newline (ASCII LF) characters to carriage-return/line-feed
character pairs for data sent to the network peripheral. Do not use
this option for binary transfers.
-p port
Connect to port on the network peripheral. The default is port
9100.
-R Do not retry connecting if the first connection attempt fails. This
option allows the retry interval and number of retries before giving
up to be controlled external to hpnpf.
-s status-file
A a series of printing events are recorded in this file The details
varies, depending on the type of printers, network interfaces, and
whether the true end-of-job is turned on or off. The status
information is recorded in the following formats:
<date>%%[ status: <status>; source:<ethernet/token ring> ]%%
<date>%%[ status: <status> ]%%
<date>%%[ printer: <printer error> ]%%
-x peripheral
Send the file to peripheral. This may be a host name or dotted
decimal Internet address.
-w Turn on true end-of-job. By default, hpnpf reports successful as
soon as all the files are sent successfully. Turning on true end-
of-job forces hpnpf to hang on until receiving a signal from the
printer indicating that the job has been completely printed. This
option is only valid for printers which implement PJL job commands,
such as LaserJet 4, 4Si, and 4 Plus.
RETURN VALUE
Hpnpf returns 0 if all the files are sent successfully (true end-of-job
is off), or when a job are printed successfully (true end-of-job is on).
It returns non-zero values if a failure was detected.
