Subject: 1 General Questions


Subject: 1.1 What is PostScript?

    PostScript is a graphics programming language.

    It is perhaps the most popular and versatile language for printers,
    being used in printers world-wide. It is capable of drawing to
    computer screens and any kind of drawing device. PostScript is
    interpreted, stack based and untyped, like the computer language
    FORTH.

    A number of programmers write PostScript programs directly for a
    variety of drawing applications. However, PostScript programs are
    usually documents meant to be printed that have been generated by a
    program written in some compiled language.


Subject: 1.2 How can I tell how many pages my document will have?

    The easiest way to count pages is view your document on-line with a
    PostScript previewer. Some previewers like Ghostview and GSPreview
    count the pages for you. (See Section 12, ``PostScript Interpreters
    and Utilities''.)

    If your document is generated by a professional program, you should
    be able to just count the number of ``%%Page:'' comments
    imbedded in the document. With UNIX you can type

  grep -c %%Page document.ps

    to do this counting. (See Section 9, ``Encapsulated PostScript''.)

    The only completely reliable way to count pages is to ask the
    printer. PostScript printers maintain a page counter that can be
    queried before and after the job is printed, and the page count is
    a simple subtraction. This tends to require rather sophisticated
    spooling systems and a communications channel that is
    bidirectional. However, some printers allow you to submit jobs on
    one port, and issue queries on another. Experts using a level 2
    printer can use the SerialOff.PS and SerialEHandlder.ps programs to
    communicate bidirectionally to the printer.


Subject: 1.3 How can I print just one page or a few pages from a big
    document? How can I print pages in reverse order?

    Try using a host-specific program, like the UNIX command psrev,
    which is part of the TranScript suite of software from Adobe
    Systems. Or use the more general utilities Ghostview, psutils or
    psxlate.

    There is no guarantee that a given PostScript document can be split
    in such a manner. The reason is that some programs which generate
    PostScript code don't conform to the Adobe Document Structuring
    Conventions (DSC). (See Section 9, ``Encapsulated PostScript''.) A
    notable example of this is Microsoft Word.


Subject: 1.4 How can I print more than one page per sheet of paper?

    Use psnup or pstext or enscript.

    These programs redefine the PostScript ``showpage'' command to do
    multiple PostScript pages per physical page. If one program doesn't
    work with a complex document, try out other ones.


Subject: 1.5 How can I edit a PostScript picture?

    If you know the PostScript programming language, just use any text
    editor to edit the code directly.

    If you want to do it visually, you can use Canvas on the Macintosh.


Subject: 1.6 How can I print PostScript on a non-PostScript printer?

    You need a tool that converts to something that your printer knows
    how to print. Use Freedom of Press, GhostScript, hp2pbm, pageview,
    TScript, or UltraScript.

Subject: 2 Printers


Subject: 2.1 How can I get my printer to talk back to me?

    Experts using a level 2 printer can use the SerialOff.PS and
    SerialEHandlder.ps programs to communicate bidirectionally to the
    printer.


Subject: 2.2 Should I leave my printer on?

    The general consensus seems to be that most computer equipment
    lasts longer if left on. This presents less thermal stress to the
    components.


Subject: 2.3 How do I suppress the power-on start page?

    Disabling the start page is described in your printer's PostScript
    supplement. The most common sequence is ``serverdict begin 0
    exitserver statusdict begin false setdostartpage end''.


Subject: 2.4 How do I make a downloaded font ``persistent''?
|
|
|  %!PS-Adobe-2.0 ExitServer
|  %%BeginExitServer: 0
|  serverdict begin 0 exitserver
|  %%EndExitServer
|  % Test for existence of font, abort if present.
|  % This won't work on a printer with a hard disk!
|  /str 32 string def
|  /Eurostile dup FontDirectory exch known
|  { str cvs print ( is already loaded!\n) print flush quit }
|  { (loading font ) print str cvs print (\n) print flush }
|  ifelse
|  %% Font follows...
|
|   The part following " Eurostile to the name of the font. The default
|   PFA behavior is to use up additional VM for the new copy if another
|   copy has already been downloaded.


Subject: 2.5 How do I remove a persistent (``permanent'') downloaded font?

    One trick for removing a persistent font (this requires that you
    knew you would need to remove it before you downloaded it) is to
    issue a ``serverdict begin 0 exitserver /magic-cookie save def''
    before downloading and sending ``serverdict begin 0 exitserver
    magic-cookie restore'' when you want to reclaim all VM used since
    the first download. The downside of this is that is uses up a save
    level, but this is usually not a problem.


Subject: 2.6 How do I reset the printer without power-cycling?

    Most printers can be reset by issuing "serverdict begin 0
    exitserver systemdict /quit get exec".


Subject: 2.7 About saving files

    Adobe recommends that driver writers do not put EOT (control-D)
    into files when saving to disk. Normally, the EOT is a part of the
    protocol for parallel and serial ports and never hits the
    PostScript interpreter.

    Drivers that do embed EOD can create problems for devices that
    allow other communication methods (e.g. AppleTalk, Ethernet, and
    SCSI) where the EOT is not part of the communications protocol. It
    is useful to redefine EOT in these instances so that the
    interpreter does not generate an error. The recommended
    redefinition is:


                   (\004) cvn {} def

    This should convert any stand-alone embedded EOTs into a null
    procedure.


Subject: 2.8 What's the control-D business?

|   PostScript printers communicating over serial lines use control-D
|   as an end of job indicator. The host computer should then wait for
|   the printer to send a control-D back to indicate that the job has
|   finished. Managing the serial protocol between host and printer
|   should be done by some form of print service, but if you're unsure
|   whether your print service is doing it, it's an idea to send one
|   yourself.
|
|   PC type computers frequently do not have any kind of printer
|   manager and applications end up sending control-D characters to the
|   printer, sometimes before and after a job. PC applications
|   frequently embed a control-D as the first character in the print
|   file, presumably to flush out any other jobs, and thereby breaking
|   the Adobe Document Structuring Conventions.
|
|   If you want to prevent applications from doing this, you could use
|   a spooler which would look at the end of every outgoing file and
|   drop the control-D on the end if there happened to be one.
|
|   If you want a spooler, check out lprps.


Subject: 2.9 Why does the printer say ``still busy'' when my document is
    done printing?

|   Sometimes when you finish a print job, the printer "Ready" light
|   keeps flashing for a minute or so. Somehow, the printer has
|   received some character(s) after the control-D which was sent
|   immediately after the PostScript file. The printer took these
|   character(s) to be another program, and eventually timed-out while
|   waiting for the rest of it. This can happen because of the host not
|   waiting for the printer to finish.


Subject: 2.10 How should I set up my spoolers?

    Since PostScript usually is prefixed with ``%!'', it's easy to
    educate your spooler to autoselect between passing raw PostScript
    through to the printer or doing an "ASCII-to-PostScript" conversion
    first. There are many packages that will do this, including
    Transcript and psxlate.

    Unfortunately, many PostScript applications generate PostScript
    without a proper "%!" magic cookie.

    The spooler should be responsible for transmitting the ``job
    termination code'' (a control-D on serially-connected printers) to
    the printer, not the application. Do yourself a favor and disable
    (or filter out) control-Ds in your applications and generate them
    in the spooler. This will be far more reliable in the face of
    arbitrary input.


Subject: 2.11 What are PPD files?
|
|   Adobe Postscript Printer Description (PPD) files describe how to
|   use the special features for a specific Postscript printer. They
|   are suppose to be human-readable, but they are really only readable
|   by PostScript gurus. It is the responsibility of the printer
|   manufacturer to supply PPD files. However, the Adobe mail server
|   has many of them. (see the Section 6, ``About Adobe'')

Subject: 3 Formats and Conversions

    This section describes all formats that can be converted to and
    from PostScript, and how to convert them. Encapsulated PostScript
    and Fonts have their own sections.


Subject: 3.1 How can I convert PostScript to some other graphics format?

    Since PostScript is not just a picture-description language, but in
    fact a complete programming language, you will need a complete
    PostScript interpreter to convert or display a PostScript graphic.
    (See Section 12, ``PostScript Interpreters and Utilities''.)

    Try using TranScript.


Subject: 3.2 How can I convert DVI to PostScript?

    Use dvips.


Subject: 3.3 How can I convert HP Laserjet language (PCL) to PostScript?

    Use lj2ps for simple PCL. Alternatively, another lj2ps, from
    psroff3.0, is a little more complete.

    hp2pbm can convert all of PCL4 (up to and including rasters,
    downloaded fonts and macros).


Subject: 3.4 How can I convert TeX PK format to PostScript?

    Psroff3.0 contains programs that can convert TeX PK format or HP
    SFP format fonts into PostScript bitmap fonts. While bitmap bfonts
    scale poorly, this is sometimes of use in special circumstances.


Subject: 3.5 How do I embed PostScript into troff?

    Most troffs can be ``coerced'' into including PostScript figures.
    The best approach is a configuration that takes EPS PostScript and
    can automatically scale it, or tell troff how big the picture is.
    Groff and DWB 3 have this built in.

    psfig is an add-on EPS inclusion handler that can add this
    capability to other versions of troff, provided that a compatible
    PostScript driver is used (Psroff 3.0 for ditroff or CAT troff,
    Transcript for ditroff). See the comp.text FAQ for more detail.


Subject: 3.6 How do I embed PostScript into LaTeX or TeX?

    You should use an add-on program for seamless PostScript inclusion.

    For generic PostScript in a professional document, use psfig.

    If your LaTeX is simple, but your PostScript is fancy, try using
    LameTeX.

    If you need a good compromise, use pstricks.

    For more detail, see the comp.text.tex FAQ.


Subject: 3.7 How can I convert an image to PostScript?

    Try PBMPLUS.

    To convert an image to PostScript in X windows, you can display the
    image on the screen and then use ``xpr -device ps'' in the
    resulting X11 window. For example, to convert GIF to PostScript,
    use xv or xshowgif (ftp from bongo.cc.utexas.edu (128.83.186.13))
    and then xpr.

    A more general alternative in X windows would be to use the PPM,
    PGM and PBM utilities in the X11R4 and X11R5 distributions.


Subject: 3.8 How can I convert ASCII text to PostScript?

    Unless your printer is smart about raw ASCII, you can't just send
    the ASCII to a PostScript printer, because the printer will attempt
    to interpret your ASCII file as PostScript code. You need a program
    which will wrap some PostScript code around your ASCII file.

    Try any of the following programs: asciiprint.ps, ato2pps, cz,
    ETSR, i2ps, lpp, lwf, POSTPRN, printer, psf, psfx80, PSR, ps2txt,
    pstext, swtext, text2ps, TranScript, spike.ps, enscript, nenscript,
    a2ps, asc2ps, ascii2ps, crossword.ps, double.ps, landscape.ps,
    numbered.ps, portrait.ps, or wide.ps.


Subject: 3.9 How can I convert PostScript to ASCII?
|
|    In general, when you say ``I want to convert PostScript to ASCII''
|    what you really mean is ``I want to convert MacWrite (which makes
|    PostScript output) to ASCII'' or ``I want to convert somebody's TeX
|    document (which I have in PostScript) to ASCII''.
|
|    Unfortunately, programs like these (if they're smart) do a lot of
|    fancy stuff like kerning, which means that where they would
|    normally execute the postscript command for
|
|
|      ``print water buffalo''
|
|    instead they execute the postscript command for
|
|
|      ``print wat''      (move a little to get the spacing *just* right)
|      ``print er''       (move a little to get the spacing *just* right)
|      ``print buff''     (move a little to get the spacing *just* right)
|      ``print alo''      (move a little to get the spacing *just* right)
|
|    So if I write a program to look through a PostScript file for
|    strings, like ps2ascii.pl, It can't tell where the words really
|    end. Here my program would see 4 strings
|
|
|  ``wat'' ``er'' ``buff'' ``alo''
|
|    And it doesn't see any difference between the spacing between
|    ``buff'' and ``alo'' (not a word break) and the spacing between
|    ``er'' and ``buff'' (a real word break).
|
|    The problem is that PostScript for text formatting is usually
|    produced machine generated by a text formatter. A PostScript
|    generator like dvips might have a special command like ``boop''
|    that differentiates between a real world break and a fake one. But
|    every text formatter that generates PostScript has their own name
|    for the ``boop'' command.
|
|    So you really want a ``PostScript -> ASCII converter for dvips
|    output''.
|
|    The only general solution I can see would be to redefine the show
|    operator to print out the currentpoint for every letter being
|    printed, like gs2asc, and then make up an ASCII page based on this
|    by sticking ASCII characters where they go in a two-dimensional
|    array. That would convert PostScript to ASCII "formatted".
|
|    But even that wouldn't solve the problem, because special bitmap
|    fonts and and standard fonts like Symbol don't always print a "P"
|    when you say the letter "P". Sometimes they print the greek Pi
|    symbol or a chess piece or a ZapfDingBat.

    Use ps2a, ps2ascii, ps2txt, ps2ascii.ps or ps2ascii.pl.

    For UNIX users, the following csh command will extract all of the
    strings from a PostScript file and print them.


  % usage: unps < infile.ps > outfile.txt
alias unps \(sed \
 \''s/%.*$//g;s/^[ \t]*[^()]*$//g;s/^[^(]*(//g;s/)[^(]*(/ /g;s/)[^)]*$//g;'\' \
 \| tr '\\012' '\\040' \| tr -s '\\040' '\\040' \; echo \'\'\)

Subject: 4 Fonts

    This section answers questions about fonts as they pertain to
    PostScript. See the comp.fonts FAQ for more information about
    fonts.


Subject: 4.1 What are .PFB and .PFA files?

    ``PFB'' stands for Printer Font Binary, and is a binary format in
    which Adobe Type 1 font programs are usually distributed for IBM PC
    and compatibles. Many application programs support fonts in this
|   format, and refer to them as ``downloadable''. The Macintosh uses a
|   different binary storage format than does the PC.

    PFB files are compressed, and as a result, cannot be sent directly
    to a PostScript printer. Application programs like dvips which use
    fonts in this format uncompress the font before sending it to the
    printer. If you would like to use a font which is in PFB format, it
    is necessary to uncompress it first, to make a PFA file. Adobe
|   Systems supply a font downloader for PC's which turns the PFB
|   format into PFA format on the fly as it's being downloaded.

    ``PFA'' stands for Printer Font ASCII, which is the uncompressed
    version of a PFB file. Once you have the PFA file, just send it to
    the printer ahead of your file, and use the font like any other.
    There are several programs which can do the conversion from PFB to
    PFA for you. Try t1utils.


Subject: 4.2 How can I convert a PostScript font to TeX's PK format?

    Use ps2pk or try out the GNU font utilities in fontutils.


Subject: 4.3 Why are Adobe fonts hidden?

    In PostScript level 1, Adobe's fonts were hidden because they
    didn't want people pirating copies instead of paying for them.
    That's why you can't do a pathforall on a charpath.

    PostScript Level Two has removed the restriction, in the words of
    the new Red Book, ``for most fonts''. There will still be some
    vendors who will want to restrict access. Japanese font vendors,
    for example, are concerned about piracy -- given the work that goes
    into an 8,000-character Kanji font.


Subject: 4.4 How do I get bitmap representations of Adobe fonts?

    On the IBM PC, use the Font Foundary program included with the
    font. If you don't have it, contact Adobe for an upgrade.


Subject: 4.5 What are some good ftp sites for fonts?


  ftp.cs.umb.edu
  sumex-aim.stanford.edu
  archive.umich.edu
  ftp.cica.indiana.edu    /pub/pc/win3/fonts
  colonsay.dcs.ed.ac.uk   /pub/postscript/fonts
  yak.css.itd.umich.edu


  For the NeXT platform, fonts are available on the NeXT-FTP-archives,
          sonata.cc.purdue.edu :/pub/next/graphics/fonts
          fiasko.rz-berlin.mpg.de :/pub/next/fonts

    For Macintosh, look in sumex-aim.stanford.edu,
    mac.archive.umich.edu, and ftp.cs.umb.edu (192.12.26.23), in
    pub/tex/ps-screenfonts.tar.Z.

    Color PostScript samples and many other PostScript programs are
    available from irisa.irisa.fr.


Subject: 4.6 How can I re-encode a font?

    See ddev.ps for an example for code that does this.


Subject: 4.7 What's the difference between a Type 1 and a Type 3 font?

    The Type 1 font format has nothing to do with TrueType, which is
    another font format defined by Apple. The Type 1 font format has
    been around quite a while, and is used on a wide variety of
    platforms to obtain scalable fonts.

    The Type 1 font format is a compact way of describing a font
    outline using a well-defined language that can be quickly
    interpreted. The language contains operations to provide the
    rasterizer with additional information about a character, known as
    hints. The Type 1 font format is defined in the book "The Adobe
    Type 1 Font Format", also known as the black-and-white book, for
    the colors on its cover.

    Most clone interpreters will not have Adobe's proprietary rendering
    technology which interprets font hints to improve the appearance of
    fonts shown at small sizes on low-resolution devices. The
    exceptions are PowerPage and UltraScript.

    The Type 3 font format is a way of packaging up PostScript
    descriptions of characters into a font, so that the PostScript
    interpreter can rasterize them. It is often easier to create a Type
    3 font program by hand than to create the corresponding Type 1 font
    program. Type 3 font programs have access to the entire PostScript
    language to do their imaging, including the 'image' operator. They
    can be used for bitmapped fonts, although that is certainly not a
    requirement. The Type 3 font format contains no provisions for
    'hinting', and as such Type 3 font programs cannot be of as high a
    quality at low resolutions as the corresponding Type 1 font
    program.

    Both formats are scalable formats, and both can be run on any
    PostScript interpreter. However, because of the requirement that a
    Type 3 font program have a full PostScript interpreter around, Type
    3 font programs cannot be understood by the Adobe Type Manager.
    Only Type 1 font programs can.

    Because of Adobe Type Manager's wide availability on a large number
    of platforms (PC, Mac, and Unix), the Type 1 font format makes an
    excellent cross-platform scalable font standard.


Subject: 4.8 What vendors sell fonts for PostScript printers?

    PostScript font vendors are many and varied. Here is a partial
    list.



    Adobe Systems
      sells a variety of fonts. With the huge number of third-party
      Type 1 vendors, in recent years Adobe have specialized in
      creating their own ``Adobe Originals'' -- high-quality fonts,
      some of which are their renditions of classic faces (Adobe
      Garamond) and some of their own devising (Stone, Utopia, ...).
      Adobe Systems, 1585 Charleston Road, Mountain View, CA 94039.

      keyboards, and others, Page Studio Graphics, 3175 North Price
      Road, # 1050, Chandler, Arizona 85224. [phone].


    RightBrain Software,
      Palo Alto, CA (415 326-2974) carry the Adobe Type library for the
      NeXT platform. If you're working on NeXT, getting fonts in the
      correct form with all the ancillary information and downloaders
      and such is important. You can convert a Mac font to NeXT (PFA)
      format, but the NeXT demands an AFM file as well, and many Mac/PC
      font vendors omit AFM files because Mac/PC apps don't use them.
      For Adobe fonts for the NeXT, save yourself a lot of hassle by
      getting the fonts from RightBrain -- they often have sales.


    The Font Company


    TreacyFaces


    URW
      supplies high-quality fonts at low prices. They are also the
      creators of the top of the line font creation and editing
      software called Ikarus. URW, 4 Manchester Street, Nashua, New
      Hampshire 03060. [phone].

    Many more font vendors exist. Look in magazines and other sources.
    Look in U & lc, published by ITC, for long lists of vendors.


Subject: 4.9 What are ATM fonts?

    There has been a rash of misunderstanding about the nature of Type
    1 fonts and what people call ATM fonts. ATM fonts are Adobe Type 1
    fonts. ATM stands for Adobe Type Manager -- a utility to render
    smooth characters on Macintosh and PC screens, from font outlines
    (Type 1 fonts) instead of using bitmap fonts. In one sense, there's
    no such thing as an ``ATM font'' -- ATM interprets Type 1 fonts, so
    there's no need to create a new name. A correctly constructed Type
    1 font can be interpreted by ATM.


Subject: 4.10 What are Multiple Master Fonts?

    Multiple Master Fonts are an extension to the Adobe font format.
    providing the ability to interpolate smoothly between several
    ``design axes'' from a single font. Design axes can include weight,
    size, and even some whacko notions like serif to sans serif.
    Adobes' first Multiple Master Font was Myriad -- a two-axis font
    with WEIGHT (light to black) on one axis, and WIDTH (condensed to
    expanded) along the other axis. In the case of Myriad, there are
    four ``polar'' designs at the ``corners'' of the design space. The
    four designs are light condensed, black condensed, light expanded,
    and black expanded.

    Given polar designs, you can set up a ``weight vector'' which
    interpolates to any point within the design space to produce a
    unique font for a specific purpose. So you can get a ``more or less
    condensed, somewhat black face''.


Subject: 4.11 Do I need a Level Two printer to use Multiple Master Fonts?

    No -- Multiple Master Fonts can be used on any PostScript printer.
    Multiple Master Fonts need a new PostScript operator known as
    makeblendedfont. The current crop of Multiple Master Fonts supply
    an emulation of this operator so the printer doesn't need this
    operator.

    A short tutorial on Multiple Master Fonts and makeblendedfont
    appears in PostScript by Example, by Henry McGilton and Mary
    Campione, published by Addison-Wesley.


Subject: 4.12 What are Type 4 fonts?

    Type 4 fonts are actually Type 1 fonts, but stored on hard disk in
    a special way to save space when they're loaded into printer RAM by
    findfont.


Subject: 4.13 What are Type 5 fonts?

    Type 5 fonts are actually Type 1 fonts, but stored in printer ROM
    in a special compressed format. They're also known as CROM fonts
    (for Compressed ROM fonts).
