Invoking `dvips'
****************
The dvips driver has a plethora of command line options. Reading
through this section will give a good idea of the capabilities of the
driver.
Many of the parameterless options listed here can be turned off by
immediately suffixing the option with a zero (0); for instance, to turn
off page reversal if it is turned on by default, use `-r0'. The
options that can be turned off in this way are `a', `f', `k', `i', `m',
`q', `r', `s', `E', `F', `K', `M', `N', `U', and `Z'.
This is a handy summary of the options; it is printed out when you run
dvips with no arguments.

Ask for additional options from standard input.
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.
`-c NUM'
Generate NUM copies of every page. Default is 1. (For collated
copies, see the `-C' option below.)
`-b NUM'
Generate NUM copies of each page, but duplicating the page body
rather than using the `#numcopies' option. This can be useful in
conjunction with a header file setting `\bop-hook' to do color
separations or other neat tricks.
`-d NUM'
Set the debug flags. This is intended only for emergencies or for
unusual fact-finding expeditions; it will work only if dvips has
been compiled with the `DEBUG' option. *Note Debug Options::, for
the possible values of NUM. Use a value of `-1', and specify the
option first, for maximum output.
`-e NUM'
Make sure that each character is placed at most this many pixels
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.
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 you must use 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.
`-h NAME'
Prepend file NAME as an additional header file. (However, if the
name is simply `-', suppress all header files from the output.)
This header file gets added to the PostScript `userdict'.
Make each section be a separate file. Under certain circumstances,
dvips will split the document up into `sections' to be processed
independently; this is most often done for memory reasons. Using
this option tells dvips to place each section into a separate
file; the new file names 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. 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.
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.
`-l NUM'
The last page printed will be the first one numbered NUM. Default
is the last page in the document. If the NUM is prefixed by an
equals sign, then it (and any argument to the `-p' option) is
treated as a sequence number, rather than a value to compare with
`\count0' values. Thus, using `-l =9' will end with the ninth
page of the document, no matter what the pages are actually
numbered.
Specify manual feed for printer.
`-mode MODE'
Use MODE as the Metafont device name for path searching and
generating fonts. 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. *Note TeX directory structure: (kpathsea)TeX
directory structure.
If Metafont seems not to understand the MODE name, see *Note
Unable to Generate Fonts::.
`-n NUM'
At most NUM pages will be printed. Default is 100000.
`-o NAME'
The output will be sent to file NAME. If no file name is given,
the default name is `FILE.ps' where the `dvi' file was called
`FILE.dvi'; if this option isn't given, any default in the
configuration file is used. If the first character of the
supplied output file 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. This option also 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.
`-p NUM'
The first page printed will be the first one numbered NUM. Default
is the first page in the document. If the NUM is prefixed by an
equals sign, then it (and any argument to the `-l' option) is
treated as a sequence number, rather than a value to compare with
`\count0' values. 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'.
The `-' range separator can also be a `:'.
Run quietly. Don't chatter about pages converted, etc.; report
nothing but errors to standard error.
Stack pages in reverse order. Normally, page 1 will be printed
first.
Causes the entire global output to be enclosed in a save/restore
pair. This causes the file to not be truly conformant, and is
thus not recommended, but is useful if you are driving the printer
directly and don't care too much about the portability of the
output.
`-t PAPERTYPE'
This sets the paper type to PAPERTYPE. The PAPERTYPE should be
defined in one of the configuration files, along with the
appropriate code to select it. See the documentation for `@'in the
configuration file option descriptions. You can also specify `-t
landscape', which rotates a document by 90 degrees. To rotate a
document whose size is not letter, you can use the `-t' option
twice, once for the page size, and once for `landscape'. The upper
left corner of each page in the `dvi' file is placed one inch from
the left and one inch from the top. Use of this option is highly
dependent on the configuration file. Note that executing the
`letter' or `a4' or other PostScript operators cause the document
to be nonconforming and can cause it not to print on certain
printers, so the default paper size should not execute such an
operator if at all possible.
`-x NUM'
Set the 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.
This option prints only the odd pages. This option uses the \TeX\
page numbering rather than the sequence page numbers.
This option prints only the even pages. This option uses the \TeX\
page numbering rather than the sequence page numbers.
`-C NUM'
Create 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 resolution in dpi (dots per inch) to NUM. 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.
Makes dvips attempt to generate an EPSF file with a tight bounding
box. This only works on one-page files, and it 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 lie 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 for creating small EPSF files
for equations or tables or the like. (Of course, `dvips' output
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 a great deal of care.)
Causes Control-D (ASCII code 4) to be appended 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 extremely small systems. Otherwise, it is not
recommended.
This option causes comments in included PostScript graphics, font
files, and headers to be removed. This is sometimes 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 some
included graphics to fail, since the PostScript header macros from
some software packages read portions of the input stream line by
line, searching for a particular comment. This option has been
turned off by default because PostScript previewers and spoolers
have been getting better.
Turns off the automatic font generation facility. If any fonts are
missing, commands to generate the fonts are appended to the file
`missfont.log' in the current directory; this file can then be
executed to create the missing fonts.
Turns off structured comments; this might 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.
`-O OFFSET'
Move the origin by a certain amount. The OFFSET is a
comma-separated pair of dimensions, such as `.1in,-.3cm' (in the
same syntax used in the `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.
`-P PRINTERNAME'
Sets up the output for the appropriate printer. This is
implemented by reading in `config.PRINTERNAME', which can then set
the output pipe (as in, `o !lpr -Pprintername') as well as the font
paths and any other defaults for that printer only. It is
recommended that all standard defaults go in the one master
`config.ps' file and only things that vary printer to printer go
in the `config.PRINTERNAME' files. Note that `config.ps' is read
before `config.PRINTERNAME'. In addition, another file called
`~/.dvipsrc' is searched for immediately after `config.ps'; this
file is intended for user defaults. If no `-P' command is given,
the environment variable `PRINTER' is checked. If that variable
exists, and a corresponding configuration file exists, that
configuration file is read in.
Run securely. This disables command execution in `\special' (via
``') and config files (via the `E' option), pipes as output files,
and opening of any absolute filenames.
`-S NUM'
Set the maximum number of pages in each `section'. This option is
most commonly used with the `-i' option; see that documentation
above for more information.
`-T OFFSET'
Set the paper size to the given pair of dimensions. This option
takes its arguments in the same style as `-O'. It overrides any
paper size special in the `dvi' file.
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. It is caused by a
bug in that interpreter that results in `garbage' on the bottom of
each character. Not recommended unless you must drive this
printer.
Download non-resident PostScript fonts as bitmaps. This requires
use of `mtpk' or `pstopk' or some combination of the two in order
to generate the required bitmap fonts; neither of these programs
are supplied with Dvips.
`-X NUM'
Set the horizontal resolution in dots per inch to NUM.
`-Y NUM'
Set the vertical resolution in dots per inch to NUM.
Causes bitmapped fonts to be compressed before they are downloaded,
thereby reducing the size of the PostScript font-downloading
information. Especially useful at high resolutions or when very
large fonts are used. Will slow down printing somewhat,
especially on early 68000-based PostScript printers.

Configuration File Searching
****************************
The dvips program has a system of loading configuration files such
that parameters can be set globally across the system, on a per-printer
basis, or by the user.
When dvips starts up, first the global `config.ps' file is searched
for and loaded. This file is looked for along the path for
configuration files, which is set in the `Makefile' at compilation.
After this master configuration file is loaded, a file by the name of
`.dvipsrc' is loaded from the current user's home directory, if such a
file exists. This file is loaded in exactly the same way as the global
configuration file, and it can override any options set in the global
file.
Then the command line is read and parsed. If the `-P' option is
encountered, at that point in the command line a configuration file for
that printer is read in. Thus, the printer configuration file can
override anything in the global or user configuration file, and it can
also override most options in the command line up to the point that the
`-P' option was encountered.
After the command line has been completely scanned, if there was no
`-P' option selected, and also the `-o' and `-f' command line options
were not used, a `PRINTER' environment variable is searched for. If
this variable exists, and a configuration file for the printer
mentioned in it exists, this configuration file is loaded last of all.
Because the printer-specific configuration files are read after the
user's configuration file, the user cannot override things in the
printer configuration files. On the other hand, the configuration path
usually includes the current directory, and can be set to include the
user's home directory (or any other directory of the user), so the user
can always provide his or her own printer-specific configuration files
that will be found before the system global ones.
A few options are treated specially, in that they are not overridden
by configuration files:
`-mode'
This overrides any mode setting (`M' line) in `config.*'. `-mode'
does not affect the resolution, however.
This overrides any output setting (`o' line) in `config.*'.
As well as setting the current resolution, this unsets the mode if
the mode was set from a configuration file. If `config.$PRINTER'
is read, however, any `D' or `M' lines from it will take effect.
The purpose of these special cases is to (1) minimize the chance of
having a mismatched mode and resolution (which `MakeTeXPK' cannot
handle), and (2) to let command-line options override config files.
* Menu:
* Config File Options:: Details of dvips config.* files.
File: dvips.info, Node: Config File Options, Up: Config File
Configuration File Options
==========================
Most of the configuration file options are similar to the command line
options, but there are a few new ones.
Again, many may be turned off by suffixing the letter with a zero (0).
These options are `a', `f', `q', `r', `K', `N', `U', and `Z'.
Within a configuration file, any empty line or line starting with a
space, asterisk, equal sign, or a pound sign is ignored.
`@ NAME HSIZE VSIZE'
This option is used to set the paper size defaults and options for
the particular printer this configuration file describes. There
are three formats for this option. If the option is specified on
a line by itself, with no parameters, it instructs dvips to
discard all other paper size information (possibly from another
configuration file) and start fresh. If three parameters are
given, as above, with the first parameter being a name and the
second and third being a dimension (as in 8.5in or 3.2cc, just
like in the `papersize' special), then the option is interpreted
as starting a new paper size description, where NAME is the name
and HSIZE and VSIZE describe the horizontal and vertical size of
the sheet of paper, respectively. If both HSIZE and VSIZE are
equal to zero (although you must still specify units!) then any
page size will match it. If the `@' character is immediately
followed by a `+' sign, then the remainder of the line (after
skipping any leading blanks) is treated as PostScript code to send
to the printer to select that particular paper size. After all
that, if the first character of the line is an exclamation point,
then the line is put in the initial comments section of the final
output file; else, it is put in the setup section of the output
file. For instance, a subset of the paper size information
supplied in the default `config.ps' looks like
@ letterSize 8.5in 11in
@ letter 8.5in 11in
@+ %%BeginPaperSize: Letter
@+ letter
@+ %%EndPaperSize
@ legal 8.5in 14in
@+ ! %%DocumentPaperSizes: Legal
@+ %%BeginPaperSize: Legal
@+ legal
@+ %%EndPaperSize
Note that you can even include structured comments in the
configuration file! When dvips has a paper format name given on
the command line, it looks for a match by the NAME; when it has a
`papersize' special, it looks for a match by dimensions. The
first match found (in the order the paper size information is
found in the configuration file) is used. If nothing matches, a
warning is printed and the first paper size given is used, so the
first paper size should always be the default. The dimensions
must match within a quarter of an inch. Landscape mode for all of
the paper sizes are automatically supported. If your printer has
a command to set a special paper size, then give dimensions of
`0in 0in'; the PostScript code that sets the paper size can refer
to the dimensions the user requested as `hsize' and `vsize'; these
will be macros defined in the PostScript that return the requested
size in default PostScript units. Note that virtually all of the
PostScript commands you use here are device dependent and degrade
the portability of the file; that is why the default first paper
size entry should not send any PostScript commands down (although a
structured comment or two would be okay). Also, some printers want
`BeginPaperSize' comments and paper size setting commands; others
(such as the NeXT) want `PaperSize' comments and they will handle
setting the paper size. There is no solution I could find that
works for both (except maybe specifying both.) See the supplied
`config.ps' file for a more realistic example.
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.
`b NUM'
Generate NUM copies of each page, but duplicating the page body
rather than using the `#numcopies' option. This can be useful in
conjunction with a header file setting `\bop-hook' to do color
separations or other neat tricks.
`e NUM'
Set the maximum drift parameter to NUM dots (pixels) as explained
above.
Run as a filter by default.
`h NAME'
Add NAME as a PostScript header file to be downloaded at the
beginning.
`i NUM'
Make each section be a separate file, and set the maximum number of
pages in a given file to NUM. Under certain circumstances, dvips
will split the document into `sections' to be processed
independently; this is most often done for memory reasons. Using
this option tells dvips to place each section into a separate
file; the new file names are created by replacing the suffix of
the supplied output file name with a three-digit sequence number.
This is essentially a combination of the command line options `-i'
and `-S'; see the documentation for these options for more
information.
`m NUM'
The value NUM is the virtual 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
Note that the number returned by this file is the total memory
free; it is often a good idea to tell dvips that the printer has
somewhat less memory. This is because many programs download
permanent macros that can reduce the memory in the printer. In
general, a memory size of about `300000' is plenty, since dvips
can automatically split a document if required. It is unfortunate
that PostScript printers with much less virtual memory still
exist. 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; the NeXT computer is
such a machine. For these systems, a value of one million works
well.
`o NAME'
The default output file is set to NAME. As above, it can be a
pipe. Useful in printer-specific configuration files to redirect
the output to a particular printer queue.
`p NAME'
The file to examine for PostScript font aliases is NAME. It
defaults to `psfonts.map'. This option allows different printers
to use different resident fonts. If the 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.
Run quietly by default.
Reverse the order of pages by default.
Enclose the entire document in a global save/restore pair by
default. Not recommended, but useful in some environments; this
breaks the conformance of the document to the Adobe PostScript
structuring conventions.
`D NUM'
Set the vertical and horizontal resolution to NUM dots per inch.
Useful in printer-specific configuration files.
`E COMMAND'
Executes the command listed; can be used to get the current date
into a header file for inclusion, for instance. Possibly
dangerous; in many installations this may be disabled, in which
case a warning message will be printed if the option is used.
`H PATH'
The (colon-separated) path to search for PostScript header files is
PATH. The environment variable `DVIPSHEADERS' overrides this.
Filter comments out of included PostScript files; see the
description above for more information.
`M MODE'
Set MODE as the METAFONT mode to be used when generating fonts and
for path searching. The `-mode' option overrides this. With the
default paths, specifying a mode this way also makes the program
assume the fonts are in a subdirectory named MODE. *Note TeX
directory structure: (kpathsea)TeX directory structure.
Disable PostScript comments by default.
`O OFFSET'
Move the origin by a certain amount. The OFFSET is a
comma-separated pair of dimensions, such as `.1in,-.3cm' (in the
same syntax as used in the `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 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.
`P PATH'
The (colon-separated) path to search for bitmap `pk' font files is
PATH. The `PKFONTS', `TEXPKS', `GLYPHFONTS', and `TEXFONTS'
environment variables override this. *Note TeX environment
variables: (kpathsea)TeX environment variables.
`R NUM NUM ...'
Sets up a list of default resolutions to search for `pk' fonts, if
the requested size is not available. The output will then scale
the font found using PostScript scaling to the requested size.
The resulting output may be ugly, and thus a warning is issued. To
turn this off, use a line with just the `R' and no numbers.
`S PATH'
The path to search for special illustrations (Encapsulated
PostScript files or psfiles) is PATH. The `TEXPICTS' and then
`TEXINPUTS' environment variables override this.
`T PATH'
The path to search for the `tfm' files is PATH. The `TFMFONTS'
and then `TEXFONTS' environment variables overrides this. This
path is used for resident fonts and fonts that can't otherwise be
found.
Turns off a memory-saving optimization; this is necessary for the
Xerox 4045 printer, but not recommended otherwise. See the
description above for more information.
`V PATH'
The path to search for virtual font `vf' files is PATH. This may
be device-dependent if you use virtual fonts to simulate actual
fonts on different devices.
`W STRING'
Sends STRING to stderr, if a parameter is given; otherwise it
cancels another previous message. This is useful in the default
configuration file if you want to require the user to specify a
printer, for instance, or if you want to notify the user that the
resultant output has special characteristics.
`X NUM'
Set the horizontal resolution to NUM dots per inch.
`Y NUM'
Set the vertical resolution to NUM dots per inch.
Compress all downloaded fonts by default, as above.

Automatic Font Generation
*************************
One major problem with TeX and the Computer Modern fonts is the huge
amount of disk space a full set of high resolution fonts can take.
Dvips solves this problem by creating fonts on demand, so only those
fonts that are actually used are stored on disk. At a typical site,
less than one-fifth of the full set of Computer Modern fonts are used
over a long period, so this saves a great deal of disk space.
Furthermore, the addition of dynamic font generation allows fonts to
be used at any size, including typesetter resolutions and extremely huge
banner sizes. Nothing special needs to be done; the fonts will be
automatically created and installed as needed.
The downside is that it does take a certain amount of time to create
a new font if it has never been used before. But once a font is
created, it will exist on disk, and the next time that document is
printed it will print very quickly.
It is the `MakeTeXPK' shell script that is responsible for making
these fonts. It *must* echo the filename of the new font (and nothing
else) to standard output. Use standard error for commentary.
`MakeTeXPK' is passed various arguments, the first of which is the
font it's supposed to make. You can override the other argument
conventions with environment variables or at compilation time; see the
Kpathsea documentation.
The `MakeTeXPK' script supplied invokes Metafont (using the Sauter
scripts first, if necessary and if they are installed) to create the
font and then copies the resultant `pk' file to a world-writable font
cache area.
`MakeTeXPK' can be customized to do other things to get the font. For
instance, if you are installing dvips to replace (or run alongside) an
existing PostScript driver, and that driver demands `gf' fonts, you can
easily modify `MakeTeXPK' to invoke `gftopk' to convert the `gf' files
to `pk' files for dvips. This provides the same space savings listed
above.
Because dvips (and thus `MakeTeXPK') is run by a wide variety of
users, there must be a system-wide place to put the cached font files.
In order for everyone to be able to supply fonts, the directory must be
world writable. If your system administrator considers this a security
hole, `MakeTeXPK' can write to `/tmp/pk' or some such directory, and
periodically the cached fonts can be moved to a more general system
area. The cache directory must exist on the `pk' file search path in
order for `MakeTeXPK' to work.

Environment Variables
*********************
Dvips reads a certain set of environment variables to configure its
operation. The path variables are read as needed, after all
configuration files are read, so they override values in the
configuration files. (Except for the `TEXCONFIG' variable.)
*Note Path specifications: (kpathsea)Path specifications, for details
of interpretation of environment variable values, and the common
environment variables. Only the environment specific to `dvips' are
mentioned here.
`DVIPSFONTS'
Default path to search for all fonts. Overrides all the
font-related config file options and other environment variables.
`DVIPSHEADERS'
Default path to search for PostScript header files. Overrides the
`H' config file option.
`DVIPSMAKEPK'
Overrides `MakeTeXPK' as the name of the program to invoke to
create missing PK fonts. You can change the arguments passed to
the `MakeTeXPK' program with the `MAKETEXPK' environment
variables; see the Kpathsea documentation.
`DVIPSSIZES'
Last-resort sizes for scaling for unfound fonts. Overrides the `R'
definition in config files.
`PRINTER'
This environment variable is read to determine which default
printer configuration file to read in. It is the responsibility of
the configuration file to send output to the proper print queue,
if such functionality is desired.
`TEXCONFIG'
This environment variable sets the directories to search for
configuration files, including the system-wide one. Using this
single environment variable and the appropriate configuration
files, it is possible to set up the program for any environment.
(The other path environment variables are thus redundant.)
`TEXPICTS'
Path to search for special illustrations. Overrides the `S' config
file option. If not set, `TEXINPUTS' is used.

************************
For special effects, if any of the macros `bop-hook', `eop-hook',
`start-hook', or `end-hook' are defined in the PostScript `userdict',
they will be executed at the beginning of a page, end of a page, start
of the document, and end of a document, respectively.
When these macros are executed, the default PostScript coordinate
system and origin is in effect. Such macros can be defined in headers
added by the `-h' option or the `header=' special, and might be useful
for writing, for instance, DRAFT across the entire page, or, with the
aid of a shell script, dating the document. These macros are executed
outside of the save/restore context of the individual pages, so it is
possible for them to accumulate information, but if a document must be
divided into sections because of memory constraints, such added
information will be lost across section breaks.
The single argument to `bop-hook' is the sequence number of the page
in the file; the first page gets zero, the second one, etc. The
procedure must leave this number on the stack. None of the other hooks
are (currently) given parameters, although this may change in the
future.
As an example of what can be done, the following special will write a
light DRAFT across each page in the document:
\special{!userdict begin /bop-hook{gsave 200 30 translate
65 rotate /Times-Roman findfont 216 scalefont setfont
0 0 moveto 0.7 setgray (DRAFT) show grestore}def end}
Note that using `bop-hook' or `eop-hook' in any way that preserves
information across pages will break compliance with the Adobe document
structuring conventions, so if you use any such tricks, it is
recommended that you also use the `-N' option to turn off structured
comments.
Several of the above tricks can be used nicely together, and it is not
necessary that a `printer configuration file' be used only to set
printer defaults. For instance, a `-P' file can be set up to print the
date on each page; the particular configuration file will execute a
command to put the date into a header file, which is then included with
a `h' line in the configuration file. Multiple `-P' options can be
used.

If you have any experience with Dvipsk under DOS, kb@cs.umb.edu would
like to hear about it.
File: dvips.info, Node: Installation, Next: Problems, Prev: MS-DOS, Up: Top
Installation
************
To compile and install Dvipsk:
1. Edit the file `make/paths.make' if you want to make changes to the
installation directories or paths that will have effect across
different runs of `configure'. Alternatively, override the Make
variables on the command line when you run Make.
Exception: to reliably change the top-level `prefix', you must give
`configure' the option `-prefix=PREFIX', instead of changing the
value in `paths.make'.
2. Edit `kpathsea/texmf.cnf.in' to change the local paths to match
your local setup. *Note Default paths: (kpathsea)Default paths,
for more details on changing the paths. A copy is in
`kpathsea/INSTALL'. See `kpathsea/HIER' for an explanation of the
default setup.
If the paths do not match where the files actually are, the
programs will probably start up Very, Very, Slowly, and/or not be
able to find the fonts or other input files.
3. `sh configure' (in the top-level directory). This makes
system-dependent `#define's' in `*/c-auto.h' (from the
corresponding `c-auto.h.in') and creates a `Makefile' (from the
corresponding `Makefile.in', by doing `@VAR@' and `ac_include'
substitutions).
Perhaps the most common desire is to compile with optimization
instead of or as well as debugging. You can change the options
passed to the compiler by changing `CFLAGS', either for
`configure' or `make'. For example:
prompt$ env CFLAGS="-g -O" configure
prompt$ make
or
prompt$ configure
prompt$ make CFLAGS="-g -O"
*Note Running `configure' scripts: (autoconf)Invoking configure,
for detailed `configure' options. (A copy is in
`kpathsea/CONFIGURE'.)
4. `make' (still in the top-level directory). Barring configuration
and compiler bugs, this will compile all the programs. *Note
Common problems: (kpathsea)Common problems, for system-dependent
problems (this section is also in `kpathsea/INSTALL').
This also creates the `texmf.cnf' and `paths.h' files that define
the default search paths.
5. Check the paths in `MakeTeXPK', unless you do not want automatic
font generation. *Note Font Generation::. The `MakeTeXPK' in the
distribution will overwrite the installed file only if the latter
contains the string `original MakeTeXPK --'.
Dvipsk, unlike the original dvips, *requires* `MakeTeXPK' to echo
the generated filename (and nothing else) to standard output
(standard error can be used for commentary). For more details, or
in general if `MakeTeXPK' fails, *note Unable to Generate Fonts::..
By default, `MakeTeXPK' installs the new PK fonts under
`/usr/local/lib/texmf/fonts/tmp/pk'. For the simplest
installation, create that directory and make it publically
writable. *Note Font Generation::, for alternatives.
6. Update the device parameters (available memory, resolution, etc.)
in `config.ps'. This file is installed as the system-wide
configuration file. *Note Config File Options::. The `config.ps'
in the distribution will overwrite the installed file only if the
latter contains the string `original config.ps --'.
If you need support for more than one device, create configuration
files for each and install them in the directory named by the Make
variable `configdir'. See the `-P' option in *Note Invoking
dvips::.
7. Install the programs and supporting macros, fonts, and data files
with `make install'. If you want to install only the executables,
do `make install-exec'; for only the data files, `make
install-data'. And if you don't want to install the fonts (perhaps
because your directory structure is different from the default),
but do want everything else, set the Make variable
`install_fonts=false'.
8. Install additional fonts, if you want to.
A few Type 1 fonts (Utopia, Charter, Courier, Nimbus, Antiqua, ...)
have been contributed to the X Consortium, and thus are freely
available. You can get TeX distributions for them from
`ftp.cs.umb.edu' in `pub/tex', and from the CTAN hosts in
`tex-archive/fonts'.
If you have a commercial Unix system, it may have come with
additional PostScript fonts. If so, you can make them available
to Dvips by (1) copying or linking them with the appropriate
filenames; and (2) running `afm2tfm' (*note afm2tfm::.) to make
TFM and VF files so the fonts will be available in the same
encoding as the fonts distributed with Dvips. Also check
`psfonts.map' to be sure the fonts are listed there (*note
Non-resident Fonts::.).
Here are the typical locations for vendor-supplied fonts:
DEC Ultrix
`/usr/lib/DPS/outline/decwin'
DEC OSF/1
`/usr/lib/X11/fonts/Type1Adobe'
IBM AIX
`/usr/lpp/DPS/fonts/outlines'
NeXT
`/NextLibrary/Fonts/outline'
SGI IRIX
`/usr/lib/DPS/outline/base'
Sun Solaris
`/usr/openwin/lib/X11/fonts/Type1/outline'
The NeXT system supplies more fonts than the others, but the sets
are overlapping. See the distributed `psfonts.map' for which
fonts each system supplies.
9. `make distclean'. This removes all files created by the build.
*Note Debug Options::, for runtime debugging options that may help
track down problems.
*Note Reporting bugs: (kpathsea)Reporting bugs, for the bug reporting
address and information. (Also at the end of `kpathsea/INSTALL'.)

Diagnosing problems
*******************
You've gone through all the trouble of installing dvips, carefully
read all the instructions in this manual, and still can't get something
to work. This is all too common, and is usually caused by some broken
PostScript application out there. The following sections provide some
helpful hints if you find yourself in such a situation.
In all cases, you should attempt to find the smallest file that causes
the problem. This will not only make debugging easier, it will also
reduce the number of possible interactions among different parts of the
system.

Debug Options
=============
The `-d' flag to dvips is very useful for helping to track down
certain errors. The parameter to this flag is an integer that tells
what errors are currently being tracked. To track a certain class of
debug messages, simply provide the appropriate number given below; if
you wish to track multiple classes, sum the numbers of the classes you
wish to track. To track all classes, you can use `-1' (output is
extremely voluminous). Another useful value is `3650', which tracks
everything having to do with file searching and opening.
The classes are:
specials
paths
fonts
pages
headers
font compression
files
memory
Kpathsea `stat' calls
Kpathsea hash table lookups
Kpathsea path element expansion
Kpathsea path searches
File: dvips.info, Node: No Output, Next: Small or Inverted, Prev: Debug Options, Up: Problems
No Output At All
================
If you are not getting any output at all, even from the simplest
one-character file (for instance, `\ \bye'), then something is very
wrong. Practically any file sent to a PostScript laser printer should
generate some output, at the very least a page detailing what error
occurred, if any. Talk to your system administrator about downloading a
PostScript error handler. (Adobe distributes a good one called
`ehandler.ps'.)
It is possible, especially if you are using non-Adobe PostScript, that
your PostScript interpreter is broken. Even then it should generate an
error message. I've tried to work around as many bugs as possible in
common non-Adobe PostScript interpreters, but I'm sure I've missed a
If dvips gives any strange error messages, or compilation on your
machine generated a lot of warnings, perhaps the dvips program itself is
broken. Carefully check the types in `dvips.h' and the declarations in
the `Makefile', and try using the debug options to determine where the
error occurred.
It is possible your spooler is broken and is misinterpreting the
structured comments. Try the `-N' flag to turn off structured comments
and see what happens.
File: dvips.info, Node: Small or Inverted, Next: Printer Errors, Prev: No Output, Up: Problems
Output Too Small or Inverted
============================
If some documents come out inverted or too small, your spooler is not
supplying an end of job indicator at the end of each file. (This
happens a lot on small machines that don't have spoolers.) You can
force dvips to do this with the `-F' flag, but note that this generates
files with a binary character (control-D) in them. You can also try
using the `-s' flag to enclose the entire job in a save/restore pair.
File: dvips.info, Node: Printer Errors, Next: 400 DPI, Prev: Small or Inverted, Up: Problems
Error Messages From Printer
===========================
If your printer returns error messages, the error message gives very
good information on what might be going wrong. One of the most common
error messages is `bop undefined'. This is caused by old versions of
Transcript and other spoolers that do not properly parse the setup
section of the PostScript. To fix this, turn off structured comments
with the `-N' option, but make sure you get your spooling software
updated.
Another error message is `VM exhausted'. (Some printers indicate
this error by locking up; others quietly reset.) This is caused by
telling dvips that the printer has more memory than it actually does,
and then printing a complicated document. To fix this, try lowering the
parameter to `m' in the configuration file; use the debug option to
make sure you adjust the correct file.
Other errors may indicate that the graphics you are trying to include
don't nest properly in other PostScript documents, or any of a number of
other possibilities. Try the output on a QMS PS-810 or other Adobe
PostScript printer; it might be a problem with the printer itself.
File: dvips.info, Node: 400 DPI, Next: Long Documents Fail, Prev: Printer Errors, Up: Problems
400 DPI Is Used Instead Of 300 DPI
==================================
This common error is caused by not editing the `config.ps' file to
reflect the correct resolution for your site. You can use the debug
flags (`-d64') to see what files are actually being read.
File: dvips.info, Node: Long Documents Fail, Next: Including Graphics Fails, Prev: 400 DPI, Up: Problems
Long Documents Fail To Print
============================
This is usually caused by incorrectly specifying the amount of memory
the printer has in `config.ps'; see the description above.
