10: .SH NAME
11: lpc \- line printer control program
12: .SH SYNOPSIS
13: .B /etc/lpc
14: [ command [ argument ... ] ]
15: .SH DESCRIPTION
16: .I Lpc
17: is used by the system administrator to control the
18: operation of the line printer system.
19: For each line printer configured in /etc/printcap,
20: .I lpc
21: may be used to:
22: .IP \(bu
23: disable or enable a printer,
24: .IP \(bu
25: disable or enable a printer's spooling queue,
26: .IP \(bu
27: rearrange the order of jobs in a spooling queue,
28: .IP \(bu
29: find the status of printers, and their associated
30: spooling queues and printer dameons.
31: .PP
32: Without any arguments,
33: .I lpc
34: will prompt for commands from the standard input.
35: If arguments are supplied,
36: .IR lpc
37: interprets the first argument as a command and the remaining
38: arguments as parameters to the command. The standard input
39: may be redirected causing
40: .I lpc
41: to read commands from file.
42: Commands may be abreviated;
43: the following is the list of recognized commands.
44: .TP
45: ? [ command ... ]
46: .TP
47: help [ command ... ]
48: .br
49: Print a short description of each command specified in the argument list,
50: or, if no arguments are given, a list of the recognized commands.
51: .TP
52: abort { all | printer ... }
53: .br
54: Terminate an active spooling daemon on the local host immediately and
55: then disable printing (preventing new daemons from being started by
56: .IR lpr )
57: for the specified printers.
58: .TP
59: clean { all | printer ... }
60: .br
61: Remove any temporary files, data files, and control files that cannot
62: be printed (i.e., do not form a complete printer job)
63: from the specified printer queue(s) on the local machine.
64: .TP
65: disable { all | printer ... }
66: .br
67: Turn the specified printer queues off. This prevents new
68: printer jobs from being entered into the queue by
69: .IR lpr .
70: .TP
71: down { all | printer } message ...
72: .br
73: Turn the specified printer queue off, disable printing and put
74: .I message
75: in the printer status file. The message doesn't need to be quoted, the
76: remaining arguments are treated like
77: .IR echo (1).
78: This is normally used to take a printer down and let others know why
79: (lpq will indicate the printer is down and print the status message).
80: .TP
81: enable { all | printer ... }
82: .br
83: Enable spooling on the local queue for the listed printers.
84: This will allow
85: .I lpr
86: to put new jobs in the spool queue.
87: .TP
88: exit
89: .TP
90: quit
91: .br
92: Exit from lpc.
93: .TP
94: restart { all | printer ... }
95: .br
96: Attempt to start a new printer daemon.
97: This is useful when some abnormal condition causes the daemon to
98: die unexpectedly leaving jobs in the queue.
99: .I Lpq
100: will report that there is no daemon present when this condition occurs.
101: If the user is the super-user,
102: try to abort the current daemon first (i.e., kill and restart a stuck daemon).
103: .TP
104: start { all | printer ... }
105: .br
106: Enable printing and start a spooling daemon for the listed printers.
107: .TP
108: status { all | printer ... }
109: Display the status of daemons and queues on the local machine.
110: .TP
111: stop { all | printer ... }
112: .br
113: Stop a spooling daemon after the current job completes and disable
114: printing.
115: .TP
116: topq printer [ jobnum ... ] [ user ... ]
117: .br
118: Place the jobs in the order listed at the top of the printer queue.
119: .TP
120: up { all | printer ... }
121: .br
122: Enable everything and start a new printer daemon. Undoes the effects of
123: .IR down .
