.TH LP 8 .SH NAME lp \- PostScript preprocessors .SH DESCRIPTION These programs are part of the .IR lp (1) suite. Each corresponds to a .I process in the .BI -p process option of .I lp and exists as an .IR rc (1) script in .B /sys/lib/lp/process that provides an interface to a PostScript conversion program in .BR /$cputype/bin/aux . The list of processors follows; after each description is a bracketed list of .I lp options to which the processor responds: .TF \fIp9bitpos\fP .TP .I dpost converts .IR troff (1) output for device .SM post to PostScript. This is used for files troff'ed on our .SM UNIX systems that do not handle .SM UTF characters. .RB [ DLcimnorxy ] .TP .I dvipost converts tex output to PostScript. .RB [ Lcinor ] .TP .I g3post converts CCITT Group 3 FAX data to PostScript. .RB [ DLm ] .TP .I gifpost converts GIF image data to PostScript. .RB [ DLm ] .TP .I generic is the default processor. It uses .IR file (1) to determine the type of input and executes the correct processor for a given (input, printer) pair. .TP .I 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 .IR face (6)). Page reversal is also done in this processor. .TP .I jpgpost converts JPEG image data to PostScript. .RB [ DLm ] .TP .I noproc passes files through untouched. .TP .I p9bitpost .na converts a Plan 9 image to PostScript, such as .B /dev/screen for the whole screen, .B /dev/window for that window's data, and .B /dev/wsys/.../window for some other window's data. .RB [ DLm ] .ad .TP .I pdfpost converts PDF data to PostScript. .TP .I post passes PostScript through, adding option patches for paper tray information. This does not always work with PostScript generated on other systems. .TP .I ppost converts .SM UTF text to PostScript. .RB [ DLcfilmnorxy ] .TP .I tr2post converts .IR troff (1) output for device .SM utf (the default) to PostScript. See .B /sys/lib/troff/font/devutf directory for troff font width table descriptions. See also the .B /sys/lib/postscript/troff directory for mappings of troff .SM UTF character space to PostScript font space. .RB [ DLcimnorxy ] .SH SOURCE .B /sys/src/cmd/postscript .SH SEE ALSO .IR lp (1) .SH BUGS The .I file command is not always smart enough to deal with certain file types. There are PostScript conversion programs that do not have processors to drive them.
