DVILJ(1)

NAME
dvilj4, dvilj4l, dvilj2p, dvilj - convert a TeX DVI file to PCL, for HP LaserJet printers

SYNOPSIS
 dvilj [--Dnumber] [-ccopies] [-dmode] [-D] [-E] [-eoutputfile]
       [-ffrompage] [-g] [-hheaderfile] [-l] [-Mflag] [-mmag] [-ppages]
       [-q] [-r] [-ttopage] [-spagesize] [-v] [-Vmode] [-w] [-xxoff(mm)]
       [-yyoff(mm)] [-Xxoff(dots)] [-Yyoff(dots)] [-z] [filename]

DESCRIPTION
dvilj and siblings convert TeX-output ".dvi" files into PCL (the Hewlett-Packard Printer Control Language) commands suitable for printing on a HP LaserJet+, HP LaserJet IIP (using dvilj2p), HP LaserJet 4 (using dvilj4), and fully compatible printers.

dvilj4 also provides support for the builtin Intellifont and TrueType fonts; TFM and VF files are provided in the distribution. Virtual fonts are not supported directly by dvilj, so you must run dvicopy(1) first, or otherwise expand the virtual fonts

All programs are generated from one source file dvi2xx.c. They are usually called via a shell script or as a line printer filter. One such script, dvihp(1), is included in the distribution. It provides command-line options similar to those of dvips(1).

OPTIONS

--Dnumber
    Debug according to the bits of number; see the kpathsea(3) manual for values. Also turns on general verbosity.

-cnumber
    Print each page number times (including original)

-dnumber
    print in duplex mode. The option -d1 means long edge binding, -d2 stands for short edge binding. This option is only selectable in dvilj4 and dvilj2p.

-D[-12]
    Double-sided printing - see below; -D1 prints odd sides only, -D2 is for even pages, a trailing - suppresses printing of empty padding pages.

-E  Switch printer into econo mode (dvilj4 only).

-eoutfile
    Send output to outfile instead of the basename of dvi file extended with ".lj". If outfile is - (as in "-e-") the output is directed to standard output and can be directly piped into a spooler.

-fpagenum
    Print pages with TeX page numbers greater than or equal to pagenum.

-g  Go mode: do not reset printer at start of job.

-hheaderfile
    Copy headerfile to output before translation of the DVI file. Used to send arbitrary commands to the laserprinter.

-l  Print output in landscape mode; supported only by dvilj2p and dvilj4.

-Mflag
    Do (not) call mktexpk(1) to generate fonts on demand. -M1 and -M are equivalent. -M0 enables invoking mktexpk(1). (This is the same as in dvips(1).) The default behavior (i.e., if no -M option is given) is chosen at compile-time; as distributed, mktexpk is enabled.

-mmagnification
    Specify the magnification to use. The following are available:

      -m#usermag e.g., #900
      -m0 equivalent to -m#1000
      -mh equivalent to -m#1095
      -m1 equivalent to -m#1200
      -mq equivalent to -m#1250
      -m2 equivalent to -m#1440
      -m3 equivalent to -m#1728
      -m4 equivalent to -m#2074
      -m5 equivalent to -m#2488

-ppagecount
    Print pagecount pages after the starting page.

-q  Quiet operation: omit final statistics, etc.

-r  Toggle page reversal.

-spagesize
    Specify the page size:

      -s1: Executive (7.25" x 10.5")
      -s2: Letter (8.5" x 11")
      -s3: Legal (8.5" x 14")
      -s6: Ledger (11" x 17")
      -s25: A5 paper (148mm x 210mm)
      -s26: A4 paper (210mm x 297mm)
      -s27: A3 (297mm x 420mm)
      -s45: JIS B5 paper (182mm x 257mm)
      -s46: JIS B4 paper (250mm x 354mm)
      -s71: Hagaki postcard (100mm x 148mm)
      -s72: Oufuku-Hagaki postcard (200mm x 148mm)
      -s80: Monarch Envelope (3 7/8" x 7 1/2")
      -s81: Commercial Envelope 10 (4 1/8" x 9 1/2")
      -s90: International DL (110mm x 220mm)
      -s91: International C5 (162mm x 229mm)
      -s100: International B5 (176mm x 250mm)

    These values are from the PCL 5 technical reference manual. If the -s commandline option is omitted, no clipping is performed at the bottom of the page. (But printing below the paper bottom should not disturb any correctly behaving PCL printer.) Please remember that the correct paper tray must be installed for selected paper size, so use this option only if you have full control over your print destination.

-tpagenum
    Print pages with TeX page numbers less than or equal to pagenum.

-v  Verbose mode: list fonts used, etc.

-Vmode
    Compatibility mode. As mode, use "K" for Kyocera, "B" for Brother, 6 for LJ6 printers.

-w  Omit warnings.

-xoffset
    Global x-offset in mm on output page relative to 1 inch/1 inch origin.

-yoffset
    Global y-offset in mm on output page relative to 1 inch/1 inch origin.

-Xoffset
    Global x-offset in dots on output page (overrides 1 inch/1 inch origin).

-Yoffset
    Global y-offset in dots on output page (overrides 1 inch/1 inch origin).

-z  Print a test page with the page counter at end of job.

OPERANDS
If no operands are specified a brief usage message is displayed.

filename
    The DVI file name that shall be converted by dvilj. It must always be seekable.

    The output file name is constructed from filename. Either an extension ".dvi" is replaced by ".lj", or the extension ".lj" is appended.

    If filename is -, the DVI file is read from standard input and the resulting PCL document is written to standard output. (Please remember that thhe DVI file must be seekable, even if it's stdin.)

SUPPORTED TeX \special COMMANDS
"\special" commands supported by dvilj have the generic syntax

  \special{key1=value key1="value with space"}
  \special{key3 = value key4 = 'note optional spaces around equal sign'}

I.e., specials are a sequence of key/value pairs, separated by an equal sign. Spaces around the equal sign are ignored. The value is either a space separated word, or a quoted string. Both double and single quotes can be used, alternatively. There is no support for quoting quote characters in values; if you want both double and single quotes in one value, you're out of luck.

The following key/value combinations are valid:

hpfile=file
    Insert file at the current position. file is searched with kpathsea(3), see below.

    The file content must be valid for this printer, i.e., it should contain PCL escape sequences or HP-GL/2 commands. If the file is a graphics file, this typically means that the upper left corner of the graphics is placed at the current position.

    PCL absolute positioning escape sequences in file are rewritten to be relative positioning commands; the lowest appearing coordinate is used as reference.

hpfile_verbatim=file
    Insert file verbatim at the current position, without any changes of the file content. file is searched with kpathsea(3), see below.

    This is mostly used to keep absolute positions in PCL files.

psfile=file llx=x0 lly=y0 urx=x1 ury=y1 rwi=s
    Convert Postscript file file to HP PCL, by Ghostscript with device "ljetplus", and insert the resulting graphics file at the current position, rewriting absolute position escape sequences. file is searched with kpathsea(3), see below.

    The accompanying key/value pairs are mandatory, they can be specified in an arbitrary order. Values x0, x1, y0, y1, and s are integers. (x0,y0) is the lower left corner, (x1,y1) the upper right corner of the image.

    Please note: The specific semantics of this special is not known. In particular, the rwi parameter is some scale factor; but even looking at the source code it is not quite clear what the special's author intended to implement here. In addition, it is unclear what dimensions are used to specify the corners, Postscript points or PCL dots.

    If you happen to know the psfile semantics, or if you spent the work analyzing them, please inform us at tex-k@tug.org, so that we can update this man page with the relevant information.

dvilj-psfile-syntax=syntax
    where syntax is either "dvilj" or "ignore". This is a very crude way to tell the driver what to do with psfile specials.

    If the value is "ignore", all psfile specials that are processed afterwards are ignored, until the next dvilj-psfile-syntax special is processed.

    If the value is "dvilj", psfiles specials are processed as explained above, until the next dvilj-psfile-syntax special is processed.

    An obvious, planned, extension is the value "dvips", but this has not been implemented yet.

    That special is not as simple as it sounds at first. Since its semantics is defined by processing order, it is only of use if it is placed on the same page as the psfile special. Having it once in a file (e.g., on the first page) does not help if you print just one page of the document -- dvilj does not do prescanning of first-page specials like some other drivers do. (Patches would be welcome, of course.)

comment=arbitrary text
comment arbitrary text
    This causes the rest of the special to be ignored; it may be used to add meta-information to a DVI file.

    With the first form, the comment may appear anywhere in the special. When it appears first, the processing of this special is terminated and all other text behind is ignored.

    The second form is a speciality that has been introduced for compatibility with other drivers. If the first keyword of the special is comment and has no value, it is taken as a valid comment syntax, too; the rest of the special is ignored.

orientation=po
    Position the page on the physical paper. The value po may be one of the following values:

      0  for portrait
      1  for landscape
      2  for reverse portrait
      3  for reverse landscape

defpoint=n(x,y)
    Define the point number n. This point can be referred to later in other special commands to specify areas that shall be filled with some pattern. n must be between 0 and 79.

    x and y are the position of that point and have the form "?pt" where "?" is a floating point number. The positions are relative to the DVI page origin; i.e., coordinates increase moving right and down, the point of origin is (1in,1in) in the upper left corner, altered by options -x, -y, -X, and -Y, but not by \hoffset and \voffset.

    x and y can be omitted, i.e., the values 3 or "4(,)" are valid. Then the current page position is used as position for point n.

resetpoints="all"
    This undefines all points again.

gray=gray_scale
grey=gray_scale
    This sets the fill mode for the next fill special, the area will be filled with gray color. (grey is an alias for gray.) Any pattern specification is reset.

    gray_scale is the percentage of gray that shall be used here; with 0 meaning white and 100 meaning black.

    Caveat: That special is actually a misnomer. PCL names these gray scales shading patterns and they are created by placing dots in the area. The gray scale selects how far spread the dots are. In the lower ranges, this doesn't look very gray on close sight, but more like a dotted background. Furthermore, the gray scales are not as fine-grained as the value range 0..100 might make you believe. In reality, there are only 8 different gray patterns available:

       1 -  2%
       3 - 10%
      11 - 20%
      21 - 35%
      36 - 55%
      56 - 80%
      81 - 99%
      100%

    One of these patterns is selected according to the gray_scale value.

pattern=pat
    This sets the fill mode for the next fill special, the area will be filled with a pattern. Any gray color specification is reset.

    pat is one of the following values:

      1  horizontal lines
      2  vertical lines
      3  diagonal lines, from lower left corner to upper right corner
      4  diagonal lines, from upper right corner to lower left corner
      5  crossed lines, vertically
      6  crossed lines, diagonally

fill=a/b
    Fill the area between the points a and b, according to the current fill mode.

    Point a must be the upper left corner and point b must be the lower left corner of the rectangle. Otherwise the result is garbage.

    The default fill mode is 10% gray color filling.

filename
    This is a legacy special, its use is depreciated. If the special is just one word that names an existing file, that file is verbatim included. Contrary to other file inclusion means, the file is not searched with kpathsea(3). You are not supposed to use this special and we won't fix any problems with it.

It should be noted that the special parser does sometimes accept constructs that are not valid as in the documentation above. Then, the output is most often damaged in some way. Proper file include specials search the file with kpathsea(3). The search path is configured by variable "DVILJINPUTS" and, if the file is not found in that search path, by variable "TEXINPUTS".

Search via "DVILJINPUTS" covers the use case that one has common site-wide graphics that shall be included in documents, e.g., scanned signatures. Search via "TEXINPUTS" covers the use case that one has graphics as part of ones current document.

"dvilj" is used as the ".PROGRAM" name in texmf.cnf, for all driver variants, independent of the actual program name. Kpathsea(3) has the concept of warning suppression with the configuration variable "TEX_HUSH", please refer to its Info node TeX support / Suppressing warnings. That variable holds a colon-separated identifiers that specifies the to-be-suppressed warnings.

If "special" is among the listed values, dvilj does not output warnings any more about specials that it doesn't know about. But if there is a recognized special and if that special has an invalid parameter, then a warning is output nevertheless, independent of the content of "TEX_HUSH".

DOUBLE PAGE PRINTING
If the printer has a duplex unit installed, duplex printing can be demanded with the -d option.

Otherwise, the command line option -D causes the printer to print in doublepage mode, that is, roughly speaking, printing first the even pages and then the odd pages of a document. If -D is used to print both even and odd pages (-D is used without the optional 1 or 2) the following will happen after half of the pages is printed: LJ: the printer stops, shows message "FEED" and switches on manual feed led. The printer continues when either the printed pages are fed into the manual page feeder, or the operator pushes the continue button (after placing first the printed pages into the paper tray).

If -D1 was specified only odd pages will be printed, -D2 can be used for even pages. A trailing "-" (as in -D-, -D1- or -D2-) supresses printing of empty pages which are generated for padding otherwise.

The driver allows the -D option for both print-directions (front-to-back or back-to-front printing). It tries to be clever in certain cases: when a document has an odd number of pages it inserts in the right place an empty page when a document starts with page 0 the driver inserts an empty page after the 0-page when a piece of a document is printed that starts with an even page-number it prints this page at the backside of the first page to ensure that the odd sides are always on the frontside. The 0-page is treated like an odd page.

The doubleside option works for all LJs, not only for the new D model with does doubleside-printing (actually, I don't know whether it makes much sense on the new LJ II D at all).

Caveat on the doubleside-option: When it is used frequently or on very large files, it might become necessary to clean the printer much more frequently.

The command line option -pX can be used to abort printing after the output of X pages (can lead to strange results together with -D). I personally dislike this option. The secure way of printing a part of a document is using -f (from) and -t (to).

ENVIRONMENT
dvilj uses the same environment variables and algorithms for finding font files as TeX and its friends do. See the documentation for the kpathsea(3) library for details. (Repeating it here is too cumbersome.)

"DVILJFONTS"
    If set, overrides all other font paths.

"DVILJMAKEPK"
    If set, overrides mktexpk(1) as the name of the command to execute to create a PK file if one isn't found.

"DVILJSIZES"
    May be set to indicate which sizes of fonts are available. It should consist of a list of numbers separated by colons. If the list begins with a colon, the system default sizes are used, as well. Sizes are expressed in dots per inch; decimals may be used for "pxl" files: for example, a 300 dots per inch file magnified by half a step comes out to 1643 dots per five inches, which should be encoded as 328.6. dvilj tries the actual size of the font before trying any of the given sizes.

"DVILJINPUTS"
    Primary search path for include files.

"TEXINPUTS"
    Secondary search path for include files.

"TEX_HUSH"
    Colon separated list of identifiers that name situations where no warning shall be output. The following identifiers are used:

      checksum  suppress mismatched font checksum warnings
      readable  suppress warnings about unreadable files
      special   suppress warnings about unknown specials
      all       suppress all warning classes above
      none      suppress no warnings

"KPATHSEA_DEBUG"
    Trace kpathsea(3) lookups; set to -1 for complete tracing.

"GS_PATH"
    On Windows, this may be the path to Ghostscript; there the default is gswin32c.exe.

    On Unix, this environment variable is not used. Ghostscript is called as gs(1) and must be found over $PATH.
