lpstat

lpstat(1)							    Apple Inc.								 lpstat(1)

NAME

       lpstat - print cups status information

SYNOPSIS

       lpstat  [ -E ] [ -H ] [ -U username ] [ -h hostname[:port] ] [ -l ] [ -W which-jobs ] [ -a [ destination(s) ] ] [ -c [ class(es) ] ] [ -d ]
       [ -o [ destination(s) ] ] [ -p [ printer(s) ] ] [ -r ] [ -R ] [ -s ] [ -t ] [ -u [ user(s) ] ] [ -v [ printer(s) ] ]

DESCRIPTION

       lpstat displays status information about the current classes, jobs, and printers. When run with no arguments, lpstat will list jobs  queued
       by the current user.

OPTIONS

       The lpstat command supports the following options:

       -E
	    Forces encryption when connecting to the server.

       -H
	    Shows the server hostname and port.

       -R
	    Shows the ranking of print jobs.

       -U username
	    Specifies an alternate username.

       -W which-jobs
	    Specifies  which  jobs  to	show,  completed  or  not-completed (the default). This option must appear before the -o option and/or any
	    printer names, otherwise the default (not-completed) value will be used in the request to the scheduler.

       -a [printer(s)]
	    Shows the accepting state of printer queues. If no printers are specified then all printers are listed.

       -c [class(es)]
	    Shows the printer classes and the printers that belong to them.  If no classes are specified then all classes are listed.

       -d
	    Shows the current default destination.

       -h server[:port]
	    Specifies an alternate server.

       -l
	    Shows a long listing of printers, classes, or jobs.

       -o [destination(s)]
	    Shows the jobs queue on the specified destinations. If no destinations are specified all jobs are shown.

       -p [printer(s)]
	    Shows the printers and whether or not they are enabled for printing. If no printers are specified then all printers are listed.

       -r
	    Shows whether the CUPS server is running.

       -s
	    Shows a status summary, including the default destination, a list of classes and their member printers, and a  list  of  printers  and
	    their associated devices. This is equivalent to using the "-d", "-c", and "-v" options.

       -t
	    Shows all status information. This is equivalent to using the "-r", "-d", "-c", "-v", "-a", "-p", and "-o" options.

       -u [user(s)]
	    Shows a list of print jobs queued by the specified users. If no users are specified, lists the jobs queued by the current user.

       -v [printer(s)]
	    Shows the printers and what device they are attached to. If no printers are specified then all printers are listed.

COMPATIBILITY

       Unlike  the  System V printing system, CUPS allows printer names to contain any printable character except SPACE, TAB, "/", and "#".  Also,
       printer and class names are not case-sensitive.

       The "-h", "-E", "-U", and "-W" options are unique to CUPS.

       The Solaris "-f", "-P", and "-S" options are silently ignored.
