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]

-u 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 operations in cupsd.conf(5).
