NAME
lp - printer output
SYNOPSIS
lp [ option ... ] [ file ... ]
DESCRIPTION
Lp is a generalized output printing service. It can be used
to queue files for printing, check a queue, or kill jobs in
a queue. The options are:
-d dest
Select the destination printer. If dest is `?', list
the currently available printers. In the absence of
`-d', the destination is taken from the environment
variable LPDEST. Destination `stdout' is the stan-
dard output. Destination `safari' is `/dev/lpt1data'
line printer port on a 386 machine, assumed to be
connected to a PostScript printer. Destinations
`hpdeskjet' and `bjc240l' are also `/dev/lpt1data'
but assumed to be connected to an HP Deskjet 670 or
Canon BJC-240. Lp can print to any printer supported
by Ghostscript using syntax gs!device where device is
a Ghostscript output device. See gs(1) and the
`canonbjc240l' entry in `/sys/lib/lp/devices'.
-k Kill the job(s) given as subsequent arguments,
instead of file names, for the given destination.
-p proc
The given processor is invoked. The default proces-
sor is `generic', which tries to do the right thing
for regular text, troff(1) output, or tex(1) output.
If no processing is desired `noproc' may be speci-
fied.
-q Print the queue for the given destination. For some
devices, include printer status.
-R Stops and restarts the printer daemon. If the
printer is wedged, it is often useful to cycle the
power on the printer before running this command.
The remaining options may be used to affect the output at a
given device. These options may not be applicable to all
devices.
-c n Print n copies.
-f font
Set the font (default `CW.11').
-H Suppress printing of header page.
-i n Select paper input tray. n may be a number 0-9, the
word `man' for the manual feed slot, and/or `simplex'
or `duplex' to get single or double sided output.

Multiple input tray options may be specified if they
are separated by commas.
-l n Set the number of lines per page to n.
-L Print pages in landscape mode (i.e. turned 90
degrees).
-m v Set magnification to v.
-n n Print n logical pages per physical page.
-o list
Print only pages whose page numbers appear in the
comma-separated list of numbers and ranges. A range
n-m means pages n through m; a range -n means from
the beginning to page n; a range n- means from page n
to the end.
-r Reverse the order of page printing.
-x v Set the horizontal offset of the print image, mea-
sured in inches.
-y v Set the vertical offset of the print image, measured
in inches.
EXAMPLES
eqn paper | troff -ms | lp -dsafari
Typeset and print a paper containing equations.
pr -l100 file | lp -l100 -fCW.8
Print a file in a small font at 100 lines per page.
lp -dstdout /dev/windows/3/window > doc.ps
Convert an image to a postscript file.
