cancel - cancel jobs
cancel [ -E ] [ -U username ] [ -a ] [ -h hostname[:port] ] [ -u
username ] [ id ] [ destination ] [ destination-id ]
cancel cancels existing print jobs. The -a option will remove all jobs
from the specified destination.
The following options are recognized by cancel:
Forces encryption when connecting to the server.
Specifies the username to use when connecting to the server.
Cancel all jobs on the named destination, or all jobs on all
destinations if none is provided.
Chooses an alternate server.
Cancels jobs owned by username.
Unlike the System V printing system, CUPS allows printer names to
contain any printable character except SPACE, TAB, "/", or "#". Also,
printer and class names are not case-sensitive.
Administrators wishing to prevent unauthorized cancellation of jobs via
the -u option should require authentication for Cancel-Jobs operations
