NAME

       cancel - cancel jobs

SYNOPSIS

       cancel [ -E ] [ -U username ] [ -a ] [ -h hostname[:port] ] [ -u username ] [ id ] [ destination ] [ destination-id ]

DESCRIPTION

       cancel cancels existing print jobs. The -a option will remove all jobs from the specified destination.

OPTIONS

       The following options are recognized by cancel:

       -E
	    Forces encryption when connecting to the server.

       -U username
	    Specifies the username to use when connecting to the server.

       -a
	    Cancel all jobs on the named destination, or all jobs on all destinations if none is provided.

       -h hostname[:port]
	    Chooses an alternate server.

       -u username
	    Cancels jobs owned by username.

COMPATIBILITY

       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.

NOTES

       Administrators wishing to prevent unauthorized cancellation of jobs via the -u option should require authentication for Cancel-Jobs  opera-
       tions in cupsd.conf(5).
