NAME
pr3287 - IBM host printing tool
SYNOPSIS
pr3287 [ options ] [ L: ] [[ LUname [, LUname ...]@] hostname [: port ]]
DESCRIPTION
pr3287 opens a telnet connection to an IBM host, and emulates an IBM 3287 printer. It
implements RFCs 2355 (TN3270E), 1576 (TN3270) and 1646 (LU name selection).
If the hostname is prefixed with L:, the connection will be made through an SSL tunnel.
pr3287 also supports TELNET START-TLS option negotiation without any need for command-line
options.
A specific LU name to use may be specified by prepending it to the hostname with an `@'.
Multiple LU names to try can be separated by commas. An empty LU can be placed in the
list with an extra comma.
The port to connect to defaults to telnet. This can be overridden by appending a port to
the hostname with a colon `:'.
OPTIONS
pr3287 understands the following options:
-assoc LUname
Causes the session to be associated with the specified LUname.
-blanklines
In LU3 formatted mode, print blank lines even if they are all NULLs or control
characters. (This is a violation of the 3270 printer protocol, but some hosts
require it.)
-charset name
Specifies an alternate host code page (input EBCDIC mapping). The default maps the
U.S. English (037) code page to the current locale character encoding. pr3287
generally supports the same host character sets as x3270.
-command command
Specifies the command to run for each print job. The default is lpr.
-crlf Causes newline characters in the output to be expanded to carriage-return/linefeed
sequences.
-daemon
Causes pr3287 to become a daemon (background) process.
-eojtimeout seconds
Causes pr3287 to flush the print job after seconds seconds of inactivity.
-ignoreeoj
Ignore TN3270E PRINT-EOJ commands, relying on UNBIND commands to indicate the ends
of print jobs.
-ffskip
Causes pr3287 to ignore a FF (formfeed) order if it occurs at the top of a page.
-ffthru
In SCS mode, causes pr3287 to pass FF (formfeed) orders through to the printer as
ASCII formfeed characters, rather than simulating them based on the values of the
MPL (maximum presentation line) and TM (top margin) parameters.
The printer can be the name of a local printer, or a UNC path to a remote printer, e.g.,
<b>\serverrinter1</b>.
-proxy type:host[:port]
Causes pr3287 to connect via the specified proxy, instead of using a direct
connection. The host can be an IP address or hostname. The optional port can be a
number or a service name. For a list of supported proxy types, see PROXY below.
-reconnect
Causes pr3287 to reconnect to the host, whenever the connection is broken. There
is a 5-second delay between reconnect attempts, to reduce network thrashing for
down or misconfigured hosts.
-trace Turns on data stream tracing. Trace information is usually saved in the file
/tmp/x3trc.pid.
-tracedir dir
Specifies the directory to save trace files in, instead of /tmp.
-trnpre file
Specifies a file containing data that will be sent to the printer before each print
job. The file contents are treated as transparent data, i.e., they are not
translated in any way.
-trnpost file
Specifies a file containing data that will be sent to the printer after each print
job. The file contents are treated as transparent data, i.e., they are not
translated in any way.
-v Display build and version information and exit.
SIGNALS
SIGINT, SIGHUP and SIGTERM cause the current print job to be flushed (any pending data to
be printed) and pr3287 to exit.
SIGUSR1 causes the current print job to be flushed without otherwise affecting the pr3287
process.
PROXY
The -proxy option causes pr3287 to use a proxy server to connect to the host. The syntax
of the option is:
type:host[:port]
The supported values for type are:
Proxy Type Protocol Default Port
───────────────────────────────────────────────────
http RFC 2817 HTTP tunnel 3128
(squid)
passthru Sun in.telnet-gw none
socks4 SOCKS version 4 1080
socks5 SOCKS version 5 (RFC 1080
1928)
telnet No protocol (just send none
connect host port)
The special types socks4a and socks5d can also be used to force the proxy server to do the
hostname resolution for the SOCKS protocol.
