3 lp \- PostScript preprocessors
5 These programs are part of the
17 .B /sys/lib/lp/process
18 that provides an interface to a PostScript conversion program in
19 .BR /$cputype/bin/aux .
20 The list of processors follows;
21 after each description is a bracketed list of
23 options to which the processor responds:
32 This is used for files troff'ed on our
34 systems that do not handle
46 converts CCITT Group 3 FAX data to PostScript.
50 converts GIF image data to PostScript.
54 is the default processor.
57 to determine the type of input and executes the correct
58 processor for a given (input, printer) pair.
61 adds a header page to the beginning of a PostScript printer
62 job so that it may be separated from other jobs in the output bin.
63 The header has the image of the job's owner from the directory of faces (see
65 Page reversal is also done in this processor.
68 converts JPEG image data to PostScript.
72 passes files through untouched.
76 converts a Plan 9 image to PostScript, such as
80 for that window's data,
82 .B /dev/wsys/.../window
83 for some other window's data.
88 converts PDF data to PostScript.
91 passes PostScript through, adding option patches for paper tray information.
92 This does not always work with PostScript generated on other systems.
105 (the default) to PostScript.
107 .B /sys/lib/troff/font/devutf
108 directory for troff font width table descriptions.
110 .B /sys/lib/postscript/troff
111 directory for mappings of
114 character space to PostScript
118 .B /sys/src/cmd/postscript
124 command is not always smart enough to deal with certain file
126 There are PostScript conversion programs that do not have processors to drive them.
