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., \\server\printer1.
-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 (squid)	3128
passthru	Sun in.telnet-gw	none
socks4	SOCKS version 4	1080
socks5	SOCKS version 5 (RFC 1928)	1080
telnet	No protocol (just send connect host port)	none

The special types socks4a and socks5d can also be used to force the proxy server to do the hostname resolution for the SOCKS protocol.
