NAME

       html2ps - convert HTML to PostScript

SYNOPSIS

       html2ps  [  -2cdDFghHLnORTuUv ] [ -b URL ] [ -C string ] [
       -e encoding ] [ -f file[:file[:...]]  ] [ -i num  ]  [  -l
       lang  ] [ -m num ] [ -N num ] [ -o file ] [ -r path ] [ -s
       num ] [ -S string ] [ -W string ] [ -x num ] [ URL|file ]

DESCRIPTION

       The program html2ps converts HTML to PostScript. The  HTML
       code  can  be  retrieved  from  one or more URL:s or local
       files, specified as parameters on the command line.  If no
       parameter is given, html2ps reads from standard input.

       Note:  To  avoid  unnecessary  network  traffic,  one  can
       rebuild an already  generated  PostScript  file  with  new
       options.  This  is  done  by  running html2ps with the new
       options, and with the old PostScript file  as  input  (not
       applicable for all options).

OPTIONS

       All  options  have  a  short  (case sensitive), and a long
       (case insensitive) form.

       -2 --twoup
              Two column (2-up) output. The default is one column
              per page.

       -b URL --base URL
              Use URL as a base to expand relative references for
              in-line images. This is useful if  you  have  down­
              loaded  a document to a local file.  The URL should
              then be the URL of the original document.

       -c --check
              Check the syntax of the HTML file (using an  exter­
              nal  syntax  checker). The default is to not make a
              syntax check.

       -C string --toc string
              Generate a  table  of  contents  (ToC).  The  value
              should be a string consisting of one of the letters
              'f', 'h', or 't', optionally combined with the let­
              ter 'b':

              b      The ToC will be printed first. This requires
                     that Ghostscript is installed.
              f      The ToC will be generated from the links  in
                     the converted document.
              h      The  ToC will be generated from headings and
                     titles in the converted documents. Note that
                     if the document author for some strange rea­
                     son has chosen to use some  other  means  to
                     represent  the  headings  than the HTML ele­
                     ments H1,...,H6, you are out of luck!
              t      The ToC will be generated from links  having
                     the attribute rev=TOC in the converted docu­
                     ment.


       -d --debug
              Generate debugging information. You  should  always
              use   this  option  when  reporting  problems  with
              html2ps.

       -D --DSC
              Generate DSC compliant  PostScript.  This  requires
              Ghostscript  and  can  take  quite some time to do.
              Note that a PostScript  file  generated  with  this
              option  cannot  be  used  as  input  to html2ps for
              reformatting later.

       -e encoding --encoding encoding
              The document encoding. Currently recognized  values
              are  ISO-8859-1, EUC-JP, SHIFT-JIS, and ISO-2022-JP
              (other EUC-xx encodings may also work). The default
              is ISO-8859-1.

       -f file[:file[:...]] --rcfile file[:file[:...]]
              A  colon separated list of configuration file names
              to use instead of the default  personal  configura­
              tion  file  $HOME/.html2psrc.   Definitions made in
              one file override  definitions  in  previous  files
              (the last file in the list has highest precedence).
              An empty file name (as in ':file',  'file1::file3',
              or  'file:')  will  expand  to the default personal
              file. The environment variable HTML2PSPATH is  used
              to  specify  the  directories  where  to search for
              these files. (Note: this is  only  supposed  to  be
              used  on  the  command line, not in a configuration
              file.)

       -F --frame
              Draw a frame around the  text  on  each  page.  The
              default is to not draw a frame.

       -g --grayscale
              Convert  colour  images  to  grayscale images. Note
              that the PostScript file will be smaller  when  the
              images  are  converted to grayscale. The default is
              to generate colour images.

       -h --help
              Show usage information.

       -H --hyphenate
              Hyphenate the text. This requires  TeX  hyphenation
              pattern files.

       -i num --scaleimage num
              Scale  in-line images with a factor num The default
              is 1.

       -l lang --language lang
              Specifies the language of the  document  (overrides
              an  eventual  LANG  attribute of the BODY element).
              The language should be given according  to  RFC1766
              (ftp://ftp.nordu.net/rfc/rfc1766.txt)  and  ISO 639
              (http://www.sil.org/sgml/iso639a.html).

       -L --landscape
              Generate code for printing in landscape  mode.  The
              default is portrait mode.

       -m num --scalemath num
              Scale  mathematical  formulas with a factor num The
              default is 1.

       -n --number
              Insert page numbers. The default is to  not  number
              the pages.

       -N num --startno num
              Specifies  the starting page number, the default is
              1.

       -o file --output file
              Write the PostScript code to file.  The default  is
              to write to standard output.

       -O --original
              Use  PostScript  original images if they exist. For
              example, if  a  document  contains  an  image  fig­
              ure.gif,  and an encapsulated PostScript file named
              figure.ps exists in the same directory,  that  file
              will  be  use instead. This only work for documents
              read as local files. Note: if the  PostScript  file
              is  large  or  contains bitmap images, this must be
              combined with the -D option. In HTML 4.0  this  can
              be achieved in a much better way with:

              <OBJECT       data="figure.ps"       type="applica­
              tion/postscript">
              <OBJECT data="figure.gif" type="image/gif">
              <PRE>[Maybe some ASCII art for text browsers]</PRE>
              </OBJECT>
              </OBJECT>


       -r path --rootdir path
              When  a  document  is  read from a local file, this
              value specifies a base directory for resolving rel­
              ative  links  starting  with  "/".  Typically, this
              should be the directory  where  your  web  server's
              home page resides.

       -R --xref
              Insert cross references at every link to within the
              set of converted documents.

       -s num --scaledoc num
              Scale the entire document with  a  factor  num  The
              default is 1.

       -S string --style string
              This  option complements/overrides definitions made
              in the configuration files. The string must  follow
              the  configuration file syntax. (Note: this is only
              supposed to be used on the command line, not  in  a
              configuration file.)

       -T --text
              Text mode, ignore images. The default is to include
              the images.

       -u --underline
              Underline text that constitutes a  hypertext  link.
              The default is to not underline.

       -U --colour
              Produce colour output for text and background, when
              specified.  The default  is  black  text  on  white
              background (mnemonic: coloUr ;-).

       -v --version
              Print  information  about  the  current  version of
              html2ps.

       -W string --web string
              Process a web of documents by recursively  retrieve
              and  convert  documents  that  are  referenced with
              hyperlinks. When dealing with remote  documents  it
              will of course be necessary to impose restrictions,
              to avoid downloading the entire  web...  The  value
              should be a string consisting of one of the letters
              'a', 'b', 'l', 'r',  or  's',  optionally  combined
              with  a  combination of the letters 'p', 'L', and a
              positive integer:

              a      Follow all links.
              b      Follow only links to within the same  direc­
                     tory, or below, as the start document.
              l      Follow  only  links  specified  with  "<LINK
                     rel=NEXT>" in the document.
              p      Prompt for each remote document.  This  mode
                     will  automatically  be  entered  after  the
                     first 50 documents.
              r      Follow only relative links.
              s      Follow only links to within the same  server
                     as the start document.
              L      With  this  option,  the  order in which the
                     documents are processed will be:  first  all
                     top  level  documents,  then  the  documents
                     linked to from these etc.  For  example,  if
                     the  document  A has links to B and C, and B
                     has a link to D, the order will be  A-B-C-D.
                     By  default,  each document will be followed
                     by the first document it links  to  etc;  so
                     the  default order for the example is A-B-D-
                     C.
              #      A positive  integer  giving  the  number  of
                     recursive levels. The default is 4 (when the
                     option is present).


       -x num --duplex num
              Generate postscript code for single or double sided
              printing.  No default, valid values are:

              0      Single sided.
              1      Double sided.
              2      Double sided, opposite page reversed (tumble
                     mode).

BUGS

       The following bugs are with respect to HTML 3.2 -  at  the
       time  of  writing the current W3C Recommendation for HTML.
       The support for HTML 4.0 is described in  another  section
       of this document.

       The IMG attributes ALIGN=LEFT and ALIGN=RIGHT are not rec­
       ognized.  This means that text flow around images does not
       work.  Also,  the  IMG  attributes  WIDTH  and  HEIGHT are
       ignored.

       The TYPE attribute in unordered lists UL is not supported.

       A  few  deviations  from the TABLE element as specified in
       HTML 3.2: It is not possible to set the border width of  a
       table.   The  WIDTH and HEIGHT attributes of the TH and TD
       elements does not work correctly  (in  my  opinion,  these
       attributes  are  bugs  in the HTML specification itself!).
       The CELLSPACING attribute is not implemented as  described
       in the specification; instead the value of the CELLPADDING
       attribute is increased by half the value of CELLSPACING.

       Rendering HTML tables well  is  a  non-trivial  task.  For
       "real"  tables,  that  is  representation of tabular data,
       html2ps usually generates  reasonably  good  output.  When
       tables  are  used  for  layout purposes, the result varies
       from good to useless. This is  because  a  table  cell  is
       never  broken  across pages. So if a table contains a cell
       with a lot of content, the entire table  may  have  to  be
       scaled  down  in  size in order to make this cell fit on a
       single page. Sometimes this may even result in  unreadable
       output.

       Page breaks are occasionally done in bad places: for exam­
       ple directly after a (long) heading, and before  the  last
       line in a paragraph.

ENVIRONMENT

       HTML2PSPATH
              This  variable  specifies the directories to search
              for configuration files. It should be a colon sepa­
              rated  list  of  directory  names. Use a dot '.' to
              denote the current directory.  An  empty  directory
              name  (as  in ':dir', 'dir1::dir3', or 'dir:') will
              expand to the directory where the global configura­
              tion  file  is. The default value is '.:', that is:
              search the current directory first,  and  then  the
              global one.

FILES

       /usr/lib/html2ps/html2psrc
              Global configuration file. See html2psrc(5).

       $HOME/.html2psrc
              User configuration file. See html2psrc(5).

       /usr/lib/html2ps/html2ps.html
