Dvips reads a DVI file as output by (for example) TeX, and converts
it to PostScript, taking care of builtin or downloaded PostScript fonts,
font reencoding, color, etc. These features are described in other
chapters in this document.
There many ways to control Dvips' behavior: configuration files,
environment variables, and command-line options.
To use Dvips at its simplest, simply type
dvips foo
where `foo.dvi' is the output of TeX that you want to print. If
Dvips has been installed correctly, the document will probably roll out
of your default printer.
If you use fonts that have not been used on your system before, they may
be automatically generated; this process can take a few minutes, so
progress reports appear by default. The next time that document is
printed, these fonts will have been saved in the proper directories, so
printing will go much faster. (If Dvips tries to endlessly generate the
same fonts over and over again, it hasn't been installed properly.
See section `Unable to generate fonts' in Kpathsea.)
Many options are available (see the next section). For a brief summary
of available options, just type
dvips --help
Dvips has a plethora of command line options. Reading through this
section will give a good idea of the capabilities of the driver.
Here is a handy summary of the options; it is printed out when you run
Dvips with no arguments or with the standard `--help' option.

Email bug reports to tex-k@mail.tug.org.
Many of the parameterless options listed here can be turned off by
suffixing the option with a zero (`0'); for instance, to turn off
page reversal, use `-r0'. Such options are marked with a trailing
`*'.
- `-'
-
Read additional options from standard input after processing the command
line.
- `--help'
-
Print a usage message and exit.
- `--version'
-
Print the version number and exit.
- `-a*'
-
Conserve memory by making three passes over the DVI file instead
of two and only loading those characters actually used. Generally only
useful on machines with a very limited amount of memory, like some PCs.
- `-A'
-
Print only the odd pages. This option uses TeX
page numbers, not physical page numbers.
- `-b num'
-
Generate num copies of each page, but duplicating the page body
rather than using the `/#copies' PostScript variable. This can
be useful in conjunction with a header file setting `bop-hook' to
do color separations or other neat tricks.
- `-B'
-
Print only the even pages. This option uses TeX page numbers, not
physical page numbers.
- `-c num'
-
Generate num consecutive copies of every page, i.e., the output is
uncollated. This merely sets the builtin PostScript variable
`/#copies'.
- `-C num'
-
Generate num copies, but collated (by replicating the data in the
PostScript file). Slower than the `-c' option, but easier on the
hands, and faster than resubmitting the same PostScript file multiple
times.
- `-d num'
-
Set the debug flags, showing what Dvips (thinks it) is doing. This will
work unless Dvips has been compiled without the `DEBUG' option (not
recommended). See section 2.4.1 Debug options, for the possible values of
num. Use `-d -1' as the first option for maximum output.
- `-D num'
-
Set both the horizontal and vertical resolution to num, given in
dpi (dots per inch). This affects the choice of bitmap fonts that are
loaded and also the positioning of letters in resident PostScript
fonts. Must be between 10 and 10000. This affects both the horizontal
and vertical resolution. If a high resolution (something greater than
400 dpi, say) is selected, the `-Z' flag should probably also be
used. If you are using fonts made with Metafont, such as Computer
Modern, `mktexpk' needs to know about the value for num
that you use or Metafont will fail. See the file
ftp://ftp.tug.org/tex/modes.mf for a list of resolutions and mode
names for most devices.
- `-e num'
-
Maximum drift in pixels of each character from its `true'
resolution-independent position on the page. The default value of this
parameter is resolution dependent (it is the number of entries in the
list [100, 200, 300, 400, 500, 600, 800, 1000, 1200, 1600, 2000, 2400,
2800, 3200, ...] that are less than or equal to the resolution in
dots per inch). Allowing individual characters to `drift' from their
correctly rounded positions by a few pixels, while regaining the true
position at the beginning of each new word, improves the spacing of
letters in words.
- `-E*'
-
Generate an EPSF file with a tight bounding box. This only looks at
marks made by characters and rules, not by any included graphics. In
addition, it gets the glyph metrics from the TFM file, so characters
that print outside their enclosing TFM box may confuse it. In addition,
the bounding box might be a bit too loose if the character glyph has
significant left or right side bearings. Nonetheless, this option works
well enough for creating small EPSF files for equations or tables or the
like. (Of course, Dvips output, especially when using bitmap fonts, is
resolution-dependent and thus does not make very good EPSF files,
especially if the images are to be scaled; use these EPSF files with
care.) For multiple page input files, also specify `-i' to get
each page as a separate EPSF file; otherwise, all the pages are overlaid
in the single output file.
- `-f*'
-
Run as a filter. Read the DVI file from standard input and write the
PostScript to standard output. The standard input must be seekable, so
it cannot be a pipe. If your input must be a pipe, write a shell script
that copies the pipe output to a temporary file and then points Dvips at
this file. This option also disables the automatic reading of the
PRINTER environment variable; use `-P$PRINTER' after the
`-f' to read it anyway. It also turns off the automatic sending of
control-D if it was turned on with the `-F' option or in the
configuration file; use `-F' after the `-f' to send it anyway.
- `-F*'
-
Write control-D (ASCII code 4) as the very last character of the
PostScript file. This is useful when Dvips is driving the printer
directly instead of working through a spooler, as is common on personal
systems. On systems shared by more than one person, this is not
recommended.
- `-h name'
-
Prepend name as an additional header file, or, if name is
`-', suppress all header files. Any definitions in the header file
get added to the PostScript `userdict'.
- `-i*'
-
Make each section be a separate file; a section is a part of the
document processed independently, most often created to avoid memory
overflow. The filenames are created replacing the suffix of the
supplied output file name by a three-digit sequence number. This option
is most often used in conjunction with the `-S' option which sets
the maximum section length in pages; if `-i' is specified and
`-S' is not, each page is output as a separate file. For instance,
some phototypesetters cannot print more than ten or so consecutive pages
before running out of steam; these options can be used to automatically
split a book into ten-page sections, each to its own file.
- `-j*'
-
Download only needed characters from Type 1 fonts. This is the
default in the current release. Some debugging flags trace this operation
(see section 2.4.1 Debug options). You can also control partial downloading on a
per-font basis (see section 6.4 `psfonts.map': PostScript font catalog).
- `-k*'
-
Print crop marks. This option increases the paper size (which should be
specified, either with a paper size special or with the `-T'
option) by a half inch in each dimension. It translates each page by a
quarter inch and draws cross-style crop marks. It is mostly useful with
typesetters that can set the page size automatically. This works by
downloading `crop.pro'.
- `-K*'
-
Remove comments in included PostScript graphics, font files, and
headers; only necessary to get around bugs in spoolers or PostScript
post-processing programs. Specifically, the `%%Page'
comments, when left in, often cause difficulties. Use of this flag can
cause other graphics to fail, however, since the PostScript header
macros from some software packages read portion the input stream line by
line, searching for a particular comment.
- `-l [=]num'
-
The last page printed will be the first one numbered num. Default
is the last page in the document. If num is prefixed by an equals
sign, then it (and the argument to the `-p' option, if specified)
is treated as a physical (absolute) page number, rather than a value to
compare with the TeX `\count0' values stored in the DVI file.
Thus, using `-l =9' will end with the ninth page of the document,
no matter what the pages are actually numbered.
- `-m*'
-
Specify manual feed, if supported by the output device.
- `-mode mode'
-
Use mode as the Metafont device name for path searching and font
generation. This overrides any value from configuration files. With
the default paths, explicitly specifying the mode also makes the program
assume the fonts are in a subdirectory named mode.
See section `TeX directory structure' in Kpathsea. If Metafont does not understand the mode name, see
section `Unable to generate fonts' in Kpathsea.
- `-M*'
-
Turns off automatic font generation (`mktexpk'). If
mktexpk, the invocation is appended to a file
`missfont.log' (by default) in the current directory. You can then
execute the log file to create the missing files after fixing the
problem.
If the current directory is not writable and the environment variable or
configuration file value `TEXMFOUTPUT' is set, its value is used.
Otherwise, nothing is written. The name `missfont.log' is
overridden by the `MISSFONT_LOG' environment variable or
configuration file value.
- `-n num'
-
Print at most num pages. Default is 100000.
- `-N*'
-
Turns off generation of structured comments such as `%%Page'; this
may be necessary on some systems that try to interpret PostScript
comments in weird ways, or on some PostScript printers. Old versions of
TranScript in particular cannot handle modern Encapsulated PostScript.
Beware: This also disables page movement, etc., in PostScript viewers
such as Ghostview.
- `-o name'
-
Send output to the file name. If `-o' is specified without
name, the default is `file.ps' where the input DVI file
was `file.dvi'. If `-o' isn't given at all, the
configuration file default is used.
If name is `-', output goes to standard output. If the first
character of name is `!' or `|', then the remainder will
be used as an argument to
popen; thus, specifying `|lpr' as
the output file will automatically queue the file for printing as
usual. (The MS-DOS version will print to the local printer device
`PRN' when name is `|lpr' and a program by that name
cannot be found.)
`-o' disables the automatic reading of the PRINTER
environment variable, and turns off the automatic sending of control-D.
See the `-f' option for how to override this.
- `-O x-offset,y-offset'
-
Move the origin by x-offset,y-offset, a comma-separated
pair of dimensions such as `.1in,-.3cm' (see section 4.1 `papersize' special). The origin of the page is shifted from the default position
(of one inch down, one inch to the right from the upper left corner of
the paper) by this amount. This is usually best specified in the
printer-specific configuration file.
This is useful for a printer that consistently offsets output pages by a
certain amount. You can use the file `testpage.tex' to determine
the correct value for your printer. Be sure to do several runs with the
same
O value--some printers vary widely from run to run.
If your printer offsets every other page consistently, instead of every
page, your best recourse is to use `bop-hook' (see section 5.3.4 PostScript hooks).
- `-p [=]num'
-
The first page printed will be the first one numbered num. Default
is the first page in the document. If num is prefixed by an
equals sign, then it (and the argument to the `-l' option, if
specified) is treated as a physical (absolute) page number, rather than
a value to compare with the TeX `\count0' values stored in the
DVI file. Thus, using `-p =3' will start with the third page of
the document, no matter what the pages are actually numbered.
- `-pp first-last'
-
Print pages first through last; equivalent to `-p
first -l last', except that multiple `-pp' options
accumulate, unlike `-p' and `-l'. The `-' separator can
also be `:'.
- `-P printer'
-
Read the configuration file `config.printer'
(`printer.cfg' on MS-DOS), which can set the output name
(most likely `o |lpr -Pprinter'), resolution, Metafont mode,
and perhaps font paths and other printer-specific defaults. It works
best to put sitewide defaults in the one master `config.ps' file
and only things that vary printer to printer in the
`config.printer' files; `config.ps' is read before
`config.printer'.
If no `-P' or `-o' is given, the environment variable
PRINTER is checked. If that variable exists, and a corresponding
`config.printer' (`printer.cfg' on MS-DOS) file
exists, it is read.
See section 3.4.1 Configuration file searching.
- `-q*'
-
Run quietly. Don't chatter about pages converted, etc. to standard
output; report no warnings (only errors) to standard error.
- `-r*'
-
Output pages in reverse order. By default, page 1 is output first.
- `-R'
-
Run securely. This disables shell command execution in
\special
(via ``', see section 5.1.4 Dynamic creation of PostScript graphics files) and config files
(via the `E' option, see section 3.4.2 Configuration file commands), pipes as
output files, and opening of any absolute filenames.
- `-s*'
-
Enclose the output in a global save/restore pair. This causes the file
to not be truly conformant, and is thus not recommended, but is useful
if you are driving a deficient printer directly and thus don't care too
much about the portability of the output to other environments.
- `-S num'
-
Set the maximum number of pages in each `section'. This option is most
commonly used with the `-i' option; see its description above for
more information.
- `-t papertype'
-
Set the paper type to papertype, usually defined in one of the
configuration files, along with the appropriate PostScript code to
select it (see section 4.2 Configuration file paper size command). You can also specify a
papertype of `landscape', which rotates a document by 90
degrees. To rotate a document whose paper type is not the default, you
can use the `-t' option twice, once for the paper type, and once
for `landscape'.
- `-T hsize,vsize'
-
Set the paper size to (hsize,vsize), a comma-separated pair
of dimensions such as `.1in,-.3cm' (see section 4.1 `papersize' special). It
overrides any paper size special in the DVI file.
- `-U*'
-
Disable a PostScript virtual memory-saving optimization that stores the
character metric information in the same string that is used to store
the bitmap information. This is only necessary when driving the Xerox
4045 PostScript interpreter, which has a bug that puts garbage on the
bottom of each character. Not recommended unless you must drive this
printer.
- `-V*'
-
Download non-resident PostScript fonts as bitmaps. This requires use
of
mtpk or gsftopk or pstopk or some combination
thereof to generate the required bitmap fonts; these programs are
supplied with Dvips. The bitmap must be put into `psfonts.map' as
the downloadable file for that font. This is useful only for those
fonts for which you do not have real outlines, being downloaded to
printers that have no resident fonts, i.e., very rarely.
- `-x num'
-
Set the x magnification ratio to num/1000. Overrides
the magnification specified in the DVI file. Must be between 10 and
100000. It is recommended that you use standard magstep values (1095,
1200, 1440, 1728, 2074, 2488, 2986, and so on) to help reduce the total
number of PK files generated. num may be a real number, not an
integer, for increased precision.
- `-X num'
-
Set the horizontal resolution in dots per inch to num.
- `-y num'
-
Set the y magnification ratio to num/1000. See
`-x' above.
- `-Y num'
-
Set the vertical resolution in dots per inch to num.
- `-z*'
-
Pass `html' hyperdvi specials through to the output for eventual
distillation into PDF. This is not enabled by default to avoid
including the header files unnecessarily, and use of temporary files in
creating the output. See section 5.4 HyperTeXt.
- `-Z*'
-
Compress bitmap fonts in the output file, thereby reducing the size of
what gets downloaded. Especially useful at high resolutions or when
very large fonts are used. May slow down printing, especially on early
68000-based PostScript printers. Generally recommend today, and can be
enabled in the configuration file (see section 3.4.2 Configuration file commands).
Dvips looks for many environment variables, to define search paths and
other things. The path variables are read as needed, after all
configuration files are read, so they override values in the
configuration files. (Except for TEXCONFIG, which defines where
the configuration files themselves are found.)
See section `Path specifications' in Kpathsea, for details of
interpretation of path and other environment variables common to all
Kpathsea-using programs. Only the environment variables specific to
Dvips are mentioned here.
DVIPSFONTS
-
Default path to search for all fonts. Overrides all the font path
config file options and other environment variables (see section `Supported file formats' in Kpathsea).
DVIPSHEADERS
-
Default path to search for PostScript header files. Overrides the `H'
config file option (see section 3.4.2 Configuration file commands).
DVIPSMAKEPK
-
Overrides `mktexpk' as the name of the program to invoke to
create missing PK fonts. You can change the arguments passed to the
mktexpk program with the MAKETEXPK environment
variable; see section `MakeTeX script arguments' in Kpathsea.
DVIPSRC
-
Specifies the name of the startup file (see section 3.4.1 Configuration file searching) which is read after `config.ps' but before any
printer-specific configuration files.
DVIPSSIZES
-
Last-resort sizes for scaling of unfound fonts. Overrides the `R'
definition in config files (see section 3.4.2 Configuration file commands).
PRINTER
-
Determine the default printer configuration file. (Dvips itself does
not use
PRINTER to determine the output destination in any way.)
TEXCONFIG
-
Path to search for Dvips' `config.printer' configuration
files, including the base `config.ps'. Using this single
environment variable, you can override everything else. (The
printer-specific configuration files are called `printer.cfg'
on MS-DOS, but `config.ps' is called by that name on all
platforms.)
TEXPICTS
-
Path to search for included graphics files. Overrides the `S'
config file option (see section 3.4.2 Configuration file commands). If not set,
TEXINPUTS is looked for. See section `Supported file formats' in Kpathsea.
This section describes in detail the Dvips-specific `config.*'
device configuration files (called `*.cfg' on MS-DOS), which
override the `texmf.cnf'
configuration files generic to Kpathsea which Dvips also reads
(see section `Config files' in Kpathsea).
For information about installing these files, including a prototype file
you can copy, see section 2.1 `config.ps' installation.
The Dvips program loads many different configuration files, so that
parameters can be set globally across the system, on a per-device basis,
or individually by each user.
-
Dvips first reads (if it exists) `config.ps'; it is searched for
along the path for Dvips configuration files, as described in
section `Supported file formats' in Kpathsea.
-
A user-specific startup file is loaded, so individual users can override
any options set in the global file. The environment variable
DVIPSRC, if defined, is used as the specification of the startup
file. If this variable is undefined, Dvips uses a platform-specific
default name. On Unix Dvips looks for the default startup file under
the name `$HOME/.dvipsrc', which is in the user's home directory.
On MS-DOS and MS-Windows, where users generally don't have their private
directories, the startup file is called `dvips.ini' and it is
searched for along the path for Dvips configuration files (as described
in section `Supported file formats' in Kpathsea.); users are
expected to set this path as they see fit for their taste.
-
The command line is read and parsed: if the `-Pdevice' option
is encountered, at that point `config.device' is loaded.
Thus, the printer configuration file can override anything in the
site-wide or user configuration file, and it can also override options
in the command line up to the point that the `-P' option was
encountered. (On MS-DOS, the printer configuration files are called
`device.cfg', since DOS doesn't allow more than 3 characters
after the dot in filenames.)
-
If no `-P' option was specified, and also the `-o' and
`-f' command line options were not used, Dvips checks the
environment variable
PRINTER. If it exists, then
`config.$PRINTER' (`$PRINTER.cfg' on MS-DOS) is
loaded (if it exists).
Because the `.dvipsrc' file is read before the printer-specific
configuration files, individual users cannot override settings in the
latter. On the other hand, the TEXCONFIG path usually includes
the current directory, and can in any case be set to anything, so the
users can always define their own printer-specific configuration files
to be found before the system's.
A few command-line options are treated specially, in that they are not
overridden by configuration files:
- `-D'
-
As well as setting the resolution, this unsets the mode, if the mode was
previously set from a configuration file. If `config.$PRINTER' is
read, however, any `D' or `M' lines from there will take
effect.
- `-mode'
-
This overrides any mode setting (`M' line) in configuration files.
`-mode' does not affect the resolution.
- `-o'
-
This overrides any output setting (`o' line) in configuration files.
The purpose of these special cases is to (1) minimize the chance of
having a mismatched mode and resolution (which `mktexpk' cannot
resolve), and (2) let command-line options override config files where
possible.
Most of the configuration file commands are similar to corresponding
command line options, but there are a few exceptions. When they are the
same, we omit the description here.
As with command line options, many may be turned off by suffixing the
letter with a zero (`0').
Within a configuration file, empty lines, and lines starting with a
space, asterisk, equal sign, percent sign, or pound sign are ignored.
There is no provision for continuation lines.
- `@ name hsize vsize'
-
Define paper sizes. See section 4.2 Configuration file paper size command.
- `a*'
-
Memory conservation. Same as `-a', see section 3.2.2 Option details.
- `b #copies'
-
Multiple copies. Same as `-b', see section 3.2.2 Option details.
- `D dpi'
-
Output resolution. Same as `-D', see section 3.2.2 Option details.
- `e num'
-
Max drift. Same as `-e', see section 3.2.2 Option details.
- `E command'
-
Executes the command listed with
system(3); can be used to get
the current date into a header file for inclusion, for instance.
Possibly dangerous; this may be disabled, in which case a warning will
be printed if the option is used (and warnings are not suppressed).
- `f*'
-
- `F'
-
Run as a filter. Same as `-f', see section 3.2.2 Option details.
- `h header'
-
Prepend header to output. Same as `h-', see section 3.2.2 Option details.
- `H path'
-
Use path to search for PostScript header files. The environment
variable
DVIPSHEADERS overrides this.
- `i n'
-
Make multiple output files. Same as `-i -S n', see section 3.2.2 Option details.
- `j*'
-
Partially download Type 1 fonts. Same as `-j', see section 3.2.2 Option details.
- `K*'
-
Remove comments from included PostScript files. Same as `-K',
see section 3.2.2 Option details.
- `m num'
-
Declare num as the memory available for fonts and strings in the
printer. Default is 180000. This value must be accurate if memory
conservation and document splitting is to work correctly. To determine
this value, send the following file to the printer:
%! Hey, we're PostScript
/Times-Roman findfont 30 scalefont setfont 144 432 moveto
vmstatus exch sub 40 string cvs show pop showpage
The number printed by this file is the total memory free; it is usually
best to tell Dvips that the printer has slightly less memory, because
many programs download permanent macros that can reduce the memory in
the printer. Some systems or printers can dynamically increase the
memory available to a PostScript interpreter, in which case this file
might return a ridiculously low number; for example, the NeXT computer
and Ghostscript. In these cases, a value of one million works fine.
- `M mode'
-
Metafont mode. Same as `-mode', see section 3.2.2 Option details.
- `N*'
-
Disable structured comments. Beware: This also turns off displaying
page numbers or changing to specific pagenumbers in PostScript viewers.
Same as `-N', see section 3.2.2 Option details.
- `o name'
-
Send output to name. Same as `-', see section 3.2.2 Option details.
In the file `config.foo', a setting like this is probably
appropriate:
o |lpr -Pfoo
The MS-DOS version will emulate spooling to lpr by printing to
the local printer device `PRN' if it doesn't find an executable
program by that name in the current directory or along the PATH.
- `O xoff,yoff'
-
Origin offset. Same as `-O', see section 3.2.2 Option details.
- `p [+]name'
-
Examine name for PostScript font aliases. Default is
`psfonts.map'. This option allows you to specify different resident
fonts that different printers may have. If name starts with a
`+' character, then the rest of the name (after any leading spaces)
is used as an additional map file; thus, it is possible to have local
map files pointed to by local configuration files that append to the
global map file. This can be used for font families.
- `P path'
-
Use path to search for bitmap PK font files is path. The
PKFONTS, TEXPKS, GLYPHFONTS, and TEXFONTS
environment variables override this. See section `Supported file formats' in Kpathsea.
- `q*'
-
- `Q'
-
Run quietly. Same as `-q', see section 3.2.2 Option details.
- `r*'
-
Page reversal. Same as `-r', see section 3.2.2 Option details.
- `R num1 num2 ...'
-
Define the list of default resolutions for PK fonts. If a font size
actually used in a document is not available and cannot be created,
Dvips will scale the font found at the closest of these resolutions to
the requested size, using PostScript scaling. The resulting output may
be ugly, and thus a warning is issued. To turn this last-resort scaling
off, use a line with just the `R' and no numbers.
The given numbers must be sorted in increasing order; any number smaller
than the preceding one is ignored. This is because it is better to
scale a font up than down; scaling down can obliterate small features in
the character shape.
The environment and config file values `DVIPSSIZES' or
`TEXSIZES' override this configuration file setting.
If no `R' settings or environment variables are specified, a list
compiled in during installation is used. This default list is defined by
the Makefile variable `default_texsizes', defined in the file
`make/paths.make'.
