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 ] [ -e ] [ -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 active 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. -e Shows all available destinations on the local network. -h server[:port] Specifies an alternate server. -l Shows a long listing of printers, classes, or jobs. -o [destination(s)] Shows the jobs queued on the specified destinations. If no destinations are specified all jobs are shown. -p [printer(s)] Shows the printers and whether 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. CONFORMING TO
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, -E, -U, and -W options are unique to CUPS. The Solaris -f, -P, and -S options are silently ignored. SEE ALSO

NAME
cupsdisable, cupsenable - stop/start printers and classes SYNOPSIS
cupsdisable [ -E ] [-U username ] [ -c ] [ -h server[:port] ] [ -r reason ] [ --hold ] destination(s) cupsenable [ -E ] [-U username ] [ -c ] [ -h server[:port] ] [ --release ] destination(s) DESCRIPTION
cupsenable starts the named printers or classes. cupsdisable stops the named printers or classes. The following options may be used: -E Forces encryption of the connection to the server. -U username Uses the specified username when connecting to the server. -c Cancels all jobs on the named destination. -h server[:port] Uses the specified server and port. --hold Holds remaining jobs on the named printer. Useful for allowing the current job to complete before performing maintenance. -r "reason" Sets the message associated with the stopped state. If no reason is specified then the message is set to "Reason Unknown". --release Releases pending jobs for printing. Use after running cupsdisable with the --hold option to resume printing. 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. The System V versions of these commands are disable and enable. They have been renamed to avoid conflicts with the bash(1) build-in com- mands of the same name. The CUPS versions of disable and enable may ask the user for an access password depending on the printing system configuration. This dif- fers from the System V versions which require the root user to execute these commands. SEE ALSO
