NAME
       cancel - send cancel requests to an LPRng print service

SYNOPSIS
       cancel [ -P printer ] [ -D debug-options ]
            [ request-ID...  ]

DESCRIPTION
       The LPRng lprm client supports an cancel interface when invoked with an
       cancel program name.  This is similar to the ex(1) and vi(1) programs.
       The supported form of the cancel command arranges for the named jobs to
       be removed from the specified print queues.  The action is identical to
       that of lprm(1), including the options, with the difference that the
       last argument on the command line can be an optional printer name.  If
       the name does not appear in the LPRng printcap database, then the name
       is assumed to be a job identifier.

       The format of request-ID should be either the identifier field value or
       the job number reported by LPQ.

OPTIONS
       -P printer
              printer name.  The destination printer is taken from the command
              line -P printer value, then the environment variables PRINTER,
              LPDEST, NPRINTER, NGPRINTER, then first entry in the printcap
              information, and and finally the default_printer entry from the
              configuration file, and then the compile time default.

       -D debug-options
              Debug options for the program.

OPERANDS
       The following operands are supported by cancel:

       ID             A request ID, as returned by lp.  Specifying a request
                      ID cancels the associated request even if it is
                      currently printing.

       printer        A printer name (for a complete list of printer names,
                      use lpq).  This method may not be supported on all
                      systems, and the -P printer form should be used instead.

ENVIRONMENT
       By default, the destination printer is taken from the command line
       printer value, then the environment variables PRINTER, LPDEST,
       NPRINTER, NGPRINTER, then first entry in the printcap information, and
       and finally the default_printer entry from the configuration file, and
       then the compile time default.

EXIT STATUS
       The following exit values are returned:

       zero (0)       Successful completion.

       non-zero (!=0) An error occurred.

DIAGNOSTICS
       Most of the diagnostics are self explanatory.
       If you are puzzled over the exact cause of failure,
       set the debugging level on (-D5) and run again.
       The debugging information will
       help you to pinpoint the exact cause of failure.
