When the output of dvi2ps is preceded by about 2 pages of PostScript code, TeX output can be printed on PostScript devices (such as an Apple LaserWriter). The current version is set to use gf format fonts at 300 dpi (gf is Generic Font format as produced by METAFONT, and is a much tighter format than the old loose-packed pxl format, which is now officially obsolete.) The Makefile allows dvi2ps to be compiled for the use of pxl files, but we strongly advise conversion to gf format. dvi2ps downloads the bitmap description of each character, once, as it is needed, for every job (i.e., resident fonts are not used). While this sounds expensive, it is not too bad. After the conversion to PostScript is done, and considering "normal documents" and 9600 baud communication, the first page can take a minute or so to transmit and print. Thereafter, pages are usually printed faster. Simple documents of 20 & 30 pages have printed at an overall average of 3.2 pages/minute (it is unlikely that you will ever get substantially better speeds than this with the program as it currently stands). More typical rates will be 2.5 pages/min. Conversion time is extra, of course, but does not seem to be excessive. There is no effective way of converting carefully rasterised fonts as produced by METAFONT into PostScript outlines, but some thought is being given to rewriting the output end of METAFONT to produce PostScript. Dvi2ps currently runs on Apollo (AEGIS) and Vax 4.2BSD machines (and shortly Macintosh XL with MacWorks). There are many problems: 1. It is not very clever about which fonts and characters to download on a per-job basis, except that each character is sent only once, just before it is needed. All character and fonts are then made resident on the printer until the end of the job. This consumes more memory on the printer (at least on the Apple LaserWriter) than is necessary, and can limit the size of the job than can be printed. "Simple" 50 page documents can be printed with room to spare (I suspect the limit is in the range of 70-100 pages for these, but we haven't tried any that large yet). On the other hand, a section out of the LaTeX test files (manual) that uses 30 or more different fonts, some of them very large, was limited to 30 pages. -------> N.B. Dvi2ps has -from and -to options to extract ranges of pages. 2. The resulting PostScript files are very large (they can easily be 5 times the size of the DVI file). 3. Character positioning is not calculated in the "official" dvitype manner, and so there are small anomalies. However, care is taken, and the result is quite acceptable (at least to many untrained eyes). In summary, it was quite easy to develop and will serve us well until something better comes along.

If you are using TranScript, and your printer's name is "ps", you would use a command sequence that looked something like this: % tex myfile % dvi2ps myfile > myfile.ps % lpr -Pps myfile.ps The first few pages will print in a very very slow fashion while the fonts are being defined. Printing speeds up a little as you get further down the document. Installation comments: ====================== In installing this software, you will need to put tex.ps in /usr/lib/tex/tex.ps. If you want to put it somewhere else, see the definition in the Makefile. tex.ps is incorporated into the PostScript file produced by dvi2ps. The font area is assumed to be /usr/lib/tex/fonts. I do not believe that that this filter supports the TEXFONTS environment path. The font area is arranged in a new fashion that will probably be showing up in other device drivers as well. All the tfm files are contained in /usr/lib/tex/fonts. If a file named SUBDIR is present in /usr/lib/tex/fonts (or whatever directory name you select), then the name of the font is taken as the name of a subdirectory in searching for the pxl file associated with the font. In other words, cmr10.1500pxl will be found in /usr/lib/tex/fonts/cmr10/cmr10.1500pxl. When the file named SUBDIR is not present, all pxl files are looked for in the directory itself, in other words, /usr/lib/tex/fonts/cmr10.1500pxl in the above example. printcap information ==================== MIT uses another program called dvipsf when the LaserWriter is used with the /etc/printcap file. dvipsf invokes dvi2ps and applef. Both dvipsf.c and applef.c are included here. MIT's printcap entry for the laserwriter reads: 7th Floor LaserWriter|lw7|7lw|laserwriter|apple|LE-MONDE|LE-MONDE-LGP|LE-MONDE-ASCII|LE-MONDE-DVI:\ :cP=LE-MONDE-LGP:cT:dP=LE-MONDE-DVI:dT:vP=LE-MONDE:\ :br#9600:rw:fc#0000374:fs#0000003:xc#0:xs#0040040:mx#0:\ :lp=/dev/ttyh5:sd=/usr/spool/lw7:pl#66:pw#89:\ :lf=/usr/spool/lw7/log:of=/usr/lib/applef:\ :md=/usr/spool/lw7/motd:vf=/usr/lib/applef:\ :df=/usr/lib/dvipsf:cf=/usr/lib/applebitf: History and acknowledgements ============================ The driver was converted by Neal Holtz of Carleton University from a Sun previewer originally written by Mark Senn and later modified by others (see dvi2ps for specifics).

file to PostScript .br (PostScript is a trademark of Adobe Systems, Inc). .SH SYNOPSIS .B dvi2ps [ .B \-a pxldir ] [-c] [-d] [-f n] [-h] [-i file] [-m n] [-n n] [-o str] [-p] [-q] [-r] [-s] [-t n] dvifile[.dvi] .br .SH DESCRIPTION .I dvi2ps Converts a DVI file to PostScript, and writes the result to standard output. The result requires a small amount of PostScript source to precede it to the printer, before it can be successfully printed. (By default, that PostScript code is prepended to the output). .TP .B \-a pxldir Specify different area for PXL files. Specifying "-a pxldir" causes directory "pxldir" to be searched for all pxl files, instead of the default directory. .TP .B \-c Create an output file in the spool directory. This is fairly Apollo-specific, and may be disabled at other sites. When given, the output is directed to a file with a unique name, created in a spool directory. .TP .B \-d n Specify device resolution. Default is 300, a possible alternative is 600 for the Varityper VT600. Use of the -d 600 flag will automatically call in the file tex6.ps in place of tex.ps. The tex6.ps file ought to be in the same directory as tex.ps. If dvi2ps was compiled with -DDEBUG, the -d flag will also select debugging output (you probably don't want to). .TP .B \-f n Specify a starting page number. (this is a TeX page number -- \\count0). .TP .B \-h Do not copy the standard header file. This option prevents the standard PostScript header file being prepended to the output. .TP .B \-i file Copy the named file to the output The contents of the file named will be copied to the output after the standard header file has been copied. .TP .B \-m0 "| -mh | -m1 | -m2 | -m3 | -m4" Specify a magstep to use to print the document. This overrides whatever might be in the DVI file. .TP .B \-m n Specify a magnification to use to print the document. This should probably be one of the magic numbers 1000, 1095, 1200, 1440, 1728, but no checking is done. Note: if your site does not have the complete set of 300 dpi fonts, this option might be disabled. .TP .B \-n n Specify the number of copies to print .TP .B \-o str Specify an printing option. valid options are "letter", "note", "legal", "landscape" and "manualfeed" (without the quotes). This argument may be repeated several times. .TP .B \-p Do not preload font information. Occasionally there may be insufficent memory to hold the information about all of the fonts in the system. Portions of the document may be converted by including the -p option on the command line. This will prevent the preloading of all fonts into the system and instead use demand loading of the font tables. .TP .B \-q Be quiet. Don't chatter about pages converted, etc. .TP .B \-r Stack pages in reverse order. Normally, the DVI pages are processed in reverse order, with the result that they are stacked in the correct order in the output tray. This option reverses that. .TP .B \-s Turn on printing of statistics. Some versions of .I dvi2ps will optionally print statistics about font usage and some other information that is generally only interesting to developers. On these systems, -s turns on the statistics printing. .TP .B \-t n Specify an ending page number. .TP .B \-w Don't print out warnings. .SH NOTES This is a `bare bones' DVI-to-PostScript program. Minimal error checking is done. .PP Not all fonts are available in the resolution needed to display on the laser printer; when a missing font is encountered, .I dvi2ps will continue to process your dvi file, and and will log a warning message. Gaps will appear in the document where the missing characters should have been. .pp It can take up to 60 seconds for the first page to be output. After a head of steam has been built up, it can roll along at 5-10 seconds per page. .SH TeX \\\\special command: This program supports use of the "\\special" command in TeX to include special PostScript code for graphics, etc. Specifying "\\special{psfile=foo.ps}" in the TeX source will result in the contents of file "foo.ps" (assumed to contain PostScript code) being copied into the output at that point. For most included graphics, the users (0,0) point will be set to the point of the \\special command with x and y coordinates increasing up and to the right and in units of PostScript points (72/inch) -- thus you must explicitly leave space above the \\special command for most graphics. For graphics produced by Apple Macintoshes (i.e., MacDraw, MacPaint, etc.), the top left corner of the drawing will be at the point of the \\special command; in this case you must leave the required space below the \\special. .PP The \\special string can contain any number of the following "keyword=value" pairs, seperated by blanks: Keyword Value Type ------- ---------- psfile string - A PostScript file to include hsize dimension - Maximum horizontal size (for clipping) vsize dimension - Maximum vertical size (for clipping) hoffset dimension - Amount to shift right voffset dimension - Amount to shift up (or down, for MacDrwgs) hscale number - A scale factor in x-dimension vscale number - A scale factor in y-dimension .PP dimensions are given in inches. .PP THUS: \\special{psfile=foo.ps hoffset=1 hscale=0.9 vscale=0.9} will shift the graphics produced by file "foo.ps" right by 1", and will draw it at 0.9 normal size. .PP hsize and vsize are given relative to the (0,0) point of the drwg and are unaffected by offsets and scales. .PP offsets are given relative to the point of the \\special command, and are unaffected by scales. .PP If Macintosh drawings are to be included, the proper laserprep file must be downloaded to the printer, either permanently or as another header file in addition to the standard "tex.ps" header file. .SH FILES *.dvi TeX DeVice Independent output file /local/tex/pxl300/%.%pxl TeX default font rasters /local/lib/ps/tex.ps PostScript support code. .SH SEE ALSO tex(1L) .SH BUGS Probably too numerous to mention. .PP There is likely a limit to the size of documents that can be printed (at least, on the Apple LaserWriter). If you get VMerrors reported when printing, use the '-f' and '-t' options, to select a range of pages. The exact limit is unknown, but is probably well in excess of 50 pages for "normal" documents, decreasing with number of different fonts used, size of fonts, etc. .SH AUTHOR(s) Mark Senn wrote the early versions of this program for the BBN BitGraph.

Scott Jones added intelligent font substitution. * Howard Trickey made it read GF files instead of PXL ones. * */ /* Basic method: * Using the local font cacheing machinery that was in the previewer, * we can easily manage to send the bitmap for each chracter only once. * Two passes are made over each page in the DVI file. The first pass * simply outputs the bitmaps for all characters on that page that haven't * been sent before. The second pass outputs all the character setting * and positioning commands. This allows us to bracket the setting portion * with PostScript save's and restore's, thus reclaiming considerable * virtual memory after each page. * * All coordinates are output in the PostScript system (TeX origin), * and in integer units of rasters (300/inch) -- except for character * widths, which are sent as floating point numbers. * * About 2 pages of PostScript support code must be sent to the LaserWriter * before this stuff goes. It is automatically included unless the * -h option is given. */ /* Change log: * * Early 1985, (nmh) -- ported sun version to Apollo. * A little later (nmh) -- changed to continue on in the event of missing * font files. * 30-Mar-85 (nmh) -- added -a option to specify a different PXL area * 30-Mar-85 (nmh) -- changed default PXL area to /pxl118 * 31-Mar-85 (nmh) -- fixed bug in OpenFontFile() regarding more than MAXOPEN * PXL files -- changed to mark files as closed in font_entry. * 7-Apr-85 (nmh) -- made command line argument decoding case insensitive. * cleaned up handling of DVI file name argument. * 30-May-85 (nmh) -- new version; hacked to output PostScript commands * 6-Jun-85 (nmh) -- added relative positioning (20% smaller PostScript output) * add -m option to specify mag * 11-Jun-85 (nmh) -- fixed bug regarding char spacings in very long "words" * 12-Jun-85 (nmh) -- v1.02 - process DVI pages in reverse order * 13-Jun-85 (nmh) -- fixed bug re PXL files getting opened too often when no PreLoad * 14-Jun-85 (nmh) -- font dict created in PostScript only when 1st char of font downloaded * add -m0 -mh -m1 etc. to specify magsteps * 16-Aug-85 (nmh) -- added -c option t0 create output file in spool area (Apollo specific) * added -h option to copy header file to output * added -o option to pass options through to PostScript * 20-Aug-85 (nmh) -- v1.03 * 24-Aug-85 (nmh) -- add -q option (for quiet operation). * changed -o option to check PostScript option * changed to output coordinates in TeX system (but * scaled to raster units) -- (0,0) at 1" in and down from * top left (better for use with different size paper). * -- v2.00 * 25-Aug-85 (nmh) -- added dictionary enclosure to Tex.ps, and output * suitable prolog here. * 26-Aug-85 (nmh) -- changes to tex.ps to support Macintosh documents. * 14-Sep-85 (nmh) -- added keyword=value decoding to \special; * 15-Sep-85 (nmh) -- added -i file option. * 23-Sep-85 (saj) -- added font substitution for case when font is * unavailable at requested mag. (a frequent occurrence * with some macro packages like LaTeX) * 7-Jun-86 (hwt) -- use gf files ("pxl" survives in variable names) * 8-Aug-86 (rkf) -- merged together the pxl and the gf versions. Define * USEPXL should you want PXL files---gf is the default * 22-Dec-87 (pam) -- suppress (but do not remove) the function of the -d * flag for debugging, so that it can be used to specify * print-engine resolution (inspired by the VariTyper 600). * 5-Jan-88 (pam) -- provide for 256 character gf fonts. */ /**********************************************************************/ /************************ Global Definitions ************************/ /**********************************************************************/ /* This version purports to drive a PostScript device (slowly) */ typedef int BOOLEAN; #define NEW(A) ((A *) malloc(sizeof(A))) /* #define DEBUG (use CFLAG instead) */ /* for massive printing of input */ /* trace information; select by -d */ /* option after filename: */ /* dviview filename -d */ /* we want to use -d for the resolution */ #ifdef DEBUG int Debug = 0; #endif /* to enable statistics reporting via -s option */ #define STATS #define BINARYOPEN fopen /* byte-oriented host version */ #define ARITHRSHIFT 1 /* define if ">>" operator is a */ /* sign-propagating arithmetic */ /* right shift */ #define USEGLOBALMAG 1 /* when defined, the dvi global */ /* magnification is applied */ /* We can leave USEGLOBALMAG undefined when we have a limited number of font magnifications (at 300dpi) available.

SYNOPSIS dvi2ps [-a pxldir] [-c] [-d n] [-f n] [-h] [-i file] [-m n] [-n n] [-o str] [-p] [-q] [-r] [-s] [-t n] dvifile[.dvi] DESCRIPTION This program converts a DVI file to PostScript, and writes the result to standard output. The result requires a small amount of PostScript source to precede it to the printer, before it can be successfully printed. (By default, that PostScript code is prepended to the output). ARGUMENTS -a pxldir - specify different area for PXL files. Specifying "-a pxldir" causes directory "pxldir" to be searched for all pxl files, instead of the default directory. -c - create an output file in the spool directory. This is fairly Apollo-specific, and may be disabled at other sites. When given, the output is directed to a file with a unique name, created in a spool directory. -d n - select resolution (300 dpi is default, 600 is possible.) Use of the flag value -d 600 brings in the header file tex6.ps Also select debugging output if program was compiled with -DDEBUG. -f n - specify a starting page number. (this is a TeX page number -- \count0). -h - do not copy the standard header file. This option prevents the standard PostScript header file being prepended to the output. -i file - copy the named file to the output The contents of the file named will be copied to the output after the standard header file has been copied. -m0 | -mh | -m1 | -m2 | -m3 | -m4 specify a magstep to use to print the document. This overrides whatever might be in the DVI file. -m n specify a magnification to use to print the document. This should probably be one of the magic numbers 1000, 1095, 1200, 1440, 1728, but no checking is done. Note: if your site does not have the complete set of 300 dpi fonts, this option might be disabled. -n n - specify the number of copies to print -o str - specify an printing option. valid options are "letter", "note", "legal", "landscape" and "manualfeed" (without the quotes). This argument may be repeated several times. -p - do not preload font information. Occasionally there may be insufficent memory to hold the information about all of the fonts in the system. Portions of the document may be converted by including the -p option on the command line. This will prevent the preloading of all fonts into the system and instead use demand loading of the font tables. -q - be quiet. Don't chatter about pages converted, etc. -r - stack pages in reverse order. Normally, the DVI pages are processed in reverse order, with the result that they are stacked in the correct order in the output tray. This option reverses that. -s - turn on printing of statistics. Some versions of dvi2ps will optionally print statistics about font usage and some other information that is generally only interesting to developers. On these systems, -s turns on the statistics printing. -t n specify an ending page number. -w Don't print out warnings. NOTES This is a `bare bones' DVI-to-PostScript program. Minimal error checking is done. Not all fonts are available in the resolution needed to display on the laser printer; when a missing font is encountered, dvi2ps will continue to process your dvi file, and and will log a warning message. Gaps will appear in the document where the missing characters should have been. It can take up to 60 seconds for the first page to be output. After a head of steam has been built up, it can roll along at 5-10 seconds per page. TeX "\special" command: ----------------------- This program supports use of the "\special" command in TeX to include special PostScript code for graphics, etc. Specifying "\special{psfile=foo.ps}" in the TeX source will result in the contents of file "foo.ps" (assumed to contain PostScript code) being copied into the output at that point. For most included graphics, the users (0,0) point will be set to the point of the \special command with x and y coordinates increasing up and to the right and in units of PostScript points (72/inch) -- thus you must explicitly leave space above the \special command for most graphics. For graphics produced by Apple Macintoshes (i.e., MacDraw, MacPaint, etc.), the top left corner of the drawing will be at the point of the \special command; in this case you must leave the required space below the \special. The \special string can contain any number of the following "keyword=value" pairs, seperated by blanks: Keyword Value Type ------- ---------- psfile string - specifies a PostScript file to include hsize dimension - specifies maximum horizontal size (for clipping) vsize dimension - specifies maximum vertical size (for clipping) hoffset dimension - specifies amount to shift right voffset dimension - specifies amount to shift up (or down, for MacDrwgs) hscale number - specifies a scale factor in x-dimension vscale number - specifies a scale factor in y-dimension dimensions are given in PostScript points (72 per inch). THUS: \special{psfile=foo.ps hoffset=72 hscale=0.9 vscale=0.9} will shift the graphics produced by file "foo.ps" right by 1", and will draw it at 0.9 normal size. hsize and vsize are given relative to the (0,0) point of the drwg and are unaffected by offsets and scales. offsets are given relative to the point of the \special command, and are unaffected by scales. If Macintosh drawings are to be included, the proper laserprep file must be downloaded to the printer, either permanently or as another header file in addition to the standard "tex.ps" header file. FILES *.dvi TeX DeVice Independent output file /local/tex/pxl300/%.%pxl TeX default font rasters /local/lib/ps/tex.ps PostScript support code. SEE ALSO tex BUGS Probably too numerous to mention. There is likely a limit to the size of documents that can be printed (at least, on the Apple LaserWriter). If you get VMerrors reported when printing, use the '-f' and '-t' options, to select a range of pages. The exact limit is unknown, but is probably well in excess of 50 pages for "normal" documents, decreasing with number of different fonts used, size of fonts, etc. If the Mac LaserPrep file has been loaded, offsets, sizes and scales in \special{} will not work properly for non-Macintosh graphics (don't ask). AUTHOR(s) Mark Senn wrote the early versions of this program for the BBN BitGraph. Stephan Bechtolsheim, Bob Brown, Richard Furuta, James Schaad and Robert Wells improved it. Norm Hutchinson ported the program to the Sun. Neal Holtz ported it to the Apollo, and then to produce PostScript.

The following functions are defined: gettochar() finds the next character, returns its code (reduced modulo 256 if necessary), and sets global variables min_m, max_m, min_n, max_n. A result of -1 indicates that there are no more characters and the postamble has been found. readbits() After a character is found, this routine fills array bits[] with the character image. The image is represented in Postscript format: the bits are packed into bytes (most significant bit first), and the bytes scan the image left-to-right, bottom-to-top. Set globals num_cols, num_rows, x_offset, y_offset (the latter give the offset of the origin from the upper bottom corner of the image, up being a positive y_offset). readpost() After the postamble is found, this routine reads it and sets the remaining global variables declared below. seekpost() rapidly finds the postamble by random accessing the file. seekchar(c) uses fseek() to find a character with code c (modulo 256), returning a nonzero result if successful.
