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.
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.
