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:
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.
post passes PostScript through, adding option patches
for paper tray information. This does not always
work with PostScript generated on other systems.
noproc passes files through untouched.
ppost converts UTF text to PostScript. [DLcfilmnorxy]
dvipost converts tex(1) output to PostScript. [Lcinor]
g3post converts CCITT Group 3 FAX data to PostScript.
p9bitpost converts a Plan 9 bitmap such as /dev/window to
PostScript. [Lm]
tr2post converts troff(1) output for device UTF (the
default) to PostScript. [DLcimnorxy]
hpost adds a header page to the beginning of a
PostScript printer job so that it may be sepa-
rated 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.

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.
