CANCEL(1)				       General Commands Manual					    CANCEL(1)

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 envi- ronment 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 sup- ported 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 vari- ables 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.
