rlprm - remove jobs from a remote line printer spooling queue
rlprm [-qNV] [-Hprinthost] [-Pprinter] [-Xproxyhost] [--debug] [--timeout=seconds] [--port=port] [-] [ job # ... ] [ username ... ]
rlprm uses TCP/IP to remove jobs you own from printers anywhere on a network. Unlike lprm, it does not require that the remote printers be explicitly known to the local system (traditionally through /etc/printcap), and thus is considerably more flexible and requires less administration. rlprm can be used anywhere a traditional lprm might be used, and is backwards compatible with traditional BSD lprm. If rlprm is invoked as lprm, it preserves all known lprm semantics, with the exceptions of those semantics mentioned in BUGS / LIMITATIONS below. rlprm can be set up, installed, and used in the same two ways as rlpr(1) (that is, either with or without the rlprd(8) proxy daemon). Please see rlpr(1) for details, and to see whether you will need to use the rlprd(8) proxy daemon or not.
Environment/Setup --debug Print gobs of debugging information. -N, --no-bind Don't try to bind to privileged port before connecting to lpd. Please see the CONFIGURING A PROXY section in rlpr(1) for information on use of this option. --port=number Select an alternate port (instead of 7290) to connect to, if using rlprd. Usually not needed. -H, --printhost=host Select the host to print to (used with -P). Instead of using -H, one can specify the hostname directly including it with the printer name with the printer@hostname syntax. -P, --printer=printername, --queue=printername Select the printer to print to (used with -H). -X, --proxy=proxyhost, --proxyhost=proxyhost Select the proxy host to use, if necessary. --timeout=seconds Set the inactivity timer. If the connection hangs for more than seconds seconds, then rlprm will give up. Use the special value `-1' to wait forever. Default timeout is 3 seconds. -V, --version Print version and exit. Behavior - Remove all of your jobs. Note that this option must be specified immediately following the end of all other options. This option is a mutant supported only for compatibility. Instead of using this, include your username as the first argument to rlprm. -q, --quiet, --silent Quiet mode - stay quiet (except for fatal errors). See BUGS / LIMITATIONS for problems using rlprm in silent-mode operation.
The following environment variables are used by rlprm: RLPR_PRINTHOST Specifies the default host's queue to remove jobs from. PRINTER or LPDEST Specifies the default printer to remove jobs from on the host. First PRINTER is consulted, then LPDEST. Note that one can also specify the host to examine by setting printer to be printer@hostname. This may be more convenient than setting RLPR_PRINTHOST, but will confuse the traditional BSD print commands. RLPR_PROXYHOST Specifies a proxy host to use, if necessary.

BUGS / LIMITATIONS
Due to limitations in the current lpd protocol, it is not currently possible to tell whether or not the job removal succeeded when operating in silent mode. Due to limitations in the current lpd protocol, it is not currently possible to emulate the superuser semantics for the `-' option. Instead, only root's jobs are removed. Due to general niavete in the lpd protocol, rlprm(1) provides a lot of room for misbehavior; it is trivial to imagine how it can be used to remove jobs that do not belong to you. Unfortunately, any security added at this point is just sugar-coating -- the underlying protocol is flawed.
