Printer status information, displays status information about the current classes, jobs, and printers. When run with no arguments, lpstat will list jobs queued by the user.
Syntax lpstat [ -E ] [ -h server ] [ -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) ] ] Options -E Force encryption when connecting to the server. -a [printer(s)] Show 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 Show the current default destination. -h server Specify the CUPS server to communicate with. -l Show a long listing of printers, classes, or jobs. -o [destination(s)] Show the jobs queue on the specified destinations. If no destina- tions are specified all jobs are shown. -p [printer(s)] Show the printers and whether or not they are enabled for print- ing. If no printers are specified then all printers are listed. -r Show whether or not the CUPS server is running. -R Show the ranking of print jobs. -s Show 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 "-p" options. -t Show all status information.

If no printers are specified then all printers are listed. -W [which-jobs] Specifies which jobs to show, completed or not-completed (the default).
