papstatus

PAPSTATUS(8)						      System Manager's Manual						      PAPSTATUS(8)

NAME

       papstatus - get the status of an AppleTalk-connected printer

SYNOPSIS

       /usr/sbin/papstatus [ -d ] [ -p printer ] [ retrytime ]

DESCRIPTION

       papstatus  is  used to obtain the current status message from an AppleTalk connected printer.  It uses the Printer Access Protocol (PAP) to
       obtain the status information.

       If no printer is specified on the command line, papstatus looks for a file called .paprc in the current directory and reads  it	to  obtain
       the  name  of  a printer.  The .paprc file should contain a single line of the form object:type@zone where each of object, :type, and @zone
       are optional.  type and zone must be proceeded by `:' and `@' respectively.  Blank lines and lines the begin with a `#' are ignored.   type
       and zone default to LaserWriter and the zone of the local host, respectively.

OPTIONS

       -d     Turns on a debugging mode that prints some extra information to standard error.

       -p printer
	      Get  status  from printer (do not consult any .paprc files to find a printer name).  The syntax for printer is the same as discussed
	      above for the .paprc file.

       retrytime
	      Normally, papstatus only gets the status from the printer once.  If retrytime is specified, the status is obtained repeatedly,  with
	      a sleep of retrytime seconds between inquiring the printer.

FILES

       .paprc		   file that contains printer name
