NAME
lp - PostScript preprocessors
DESCRIPTION
These programs are part of the lp(1) suite. Each corre-
sponds to a process in the -pprocess option of lp and exists
as an rc(1) script in /sys/lib/lp/process that provides an
interface to a PostScript conversion program in
/$cputype/bin/aux. The list of processors follows; after
each description is a bracketed list of lp options to which
the processor responds:
dpost converts troff(1) output for device post to
PostScript. This is used for files troff'ed on
our UNIX systems that do not handle UTF charac-
ters. [DLcimnorxy]
dvipost converts tex output to PostScript. [Lcinor]
g3post converts CCITT Group 3 FAX data to PostScript.
[DLm]
gifpost converts GIF image data to PostScript. [DLm]
generic is the default processor. It uses file(1) to
determine the type of input and executes the cor-
rect processor for a given (input, printer) pair.
hpost adds a header page to the beginning of a
PostScript printer job so that it may be separated
from other jobs in the output bin. The header has
the image of the job's owner from the directory of
faces (see face(6)). Page reversal is also done in
this processor.
jpgpost converts JPEG image data to PostScript. [DLm]
noproc passes files through untouched.
p9bitpost converts a Plan 9 image to PostScript, such as
/dev/screen for the whole screen, /dev/window for
that window's data, and /dev/wsys/.../window for
some other window's data. [DLm]
pdfpost converts PDF data to PostScript.
post passes PostScript through, adding option patches
for paper tray information. This does not always
work with PostScript generated on other systems.
ppost converts UTF text to PostScript. [DLcfilmnorxy]
tr2post converts troff(1) output for device utf (the
default) to PostScript. See
/sys/lib/troff/font/devutf directory for troff
font width table descriptions. See also the
/sys/lib/postscript/troff directory for mappings
of troff UTF character space to PostScript font
space. [DLcimnorxy]

BUGS
The file command is not always smart enough to deal with
certain file types. There are PostScript conversion pro-
grams that do not have processors to drive them.
