      <para>
        Printing in Wine can be done in one of two ways:
      </para>
      <orderedlist>
        <listitem>
          <para>
            Use the built-in Wine PostScript driver (+ ghostscript to produce
            output for non-PostScript printers).
          </para>
        </listitem>
        <listitem>
          <para>Use an external windows 3.1 printer driver (outdated, probably won't get supported any more).</para>
        </listitem>
      </orderedlist>

      <para>
        Note that at the moment WinPrinters (cheap, dumb printers that require
        the host computer to explicitly control the head) will not work with
        their Windows printer drivers.  It is unclear whether they ever will.
      </para>

      <sect3>
        <title>Built-in Wine PostScript driver</title>
        <para>
          Enables printing of PostScript files via a driver built into Wine. See
          below for installation instructions. The code for the PostScript
          driver is in <filename>dlls/wineps/</filename>.
        </para>
        <para>
          The driver behaves as if it were a DRV file called
          <filename>wineps.drv</filename> which at the moment is built into
          Wine.
          Although it mimics a 16 bit driver, it will work with both 16 and 32
          bit apps, just as win9x drivers do.
        </para>
      </sect3>

<!--
      <sect3>
        <title>External printer drivers (non-working as of Jul 8, 01)</title>
        <para>
          At present only 16 bit drivers will work (note that these include
          win9x drivers).  To use them, add
        </para>
        <screen>
printer=on
        </screen>
        <para>
          to the [wine] section of the wine config file. This lets
          <function>CreateDC</function> proceed if its driver argument is a 16
          bit driver. You will probably also need to add
        </para>
        <screen>
"TTEnable" = "0" "TTOnly" = "0"
        </screen>
        <para>
          to the [TrueType] section of <filename>~/.wine/config</filename>. The code for
          the driver interface is in <filename>graphics/win16drv</filename>.
        </para>
      </sect3>

      <sect3>
        <title>Spooling</title>
        <para>
          Spooling is rather primitive. The [spooler] section of
          the wine config file maps a port (e.g.
          <systemitem>LPT1:</systemitem>) to a file or a command via a pipe. For
          example the following lines
        </para>
        <screen>
"LPT1:" = "foo.ps"
"LPT2:" = "|lpr"
        </screen>
        <para>
          map <systemitem>LPT1:</systemitem> to file <filename>foo.ps</filename>
          and <systemitem>LPT2:</systemitem> to the <command>lpr</command>
          command. If a job is sent to an unlisted port, then a file is created
          with that port's name; e.g. for <systemitem>LPT3:</systemitem> a file
          called <systemitem>LPT3:</systemitem> would be created.
        </para>
        <para>
          There are now also virtual spool queues called
          <systemitem>LPR:printername</systemitem>, which send the data
          to <command>lpr -Pprintername</command>. You do not need to
          specify those in the config file, they are handled automatically by
          <filename>dlls/gdi/printdrv.c</filename>.
        </para>
      </sect3>
    </sect2>

      <title>The Wine PostScript Driver</title>

      <para>
        (Extracted from <filename>wine/documentation/psdriver</filename>)
      </para>

      <para>
        This allows Wine to generate PostScript files without
        needing an external printer driver. Wine in this case uses the
        system provided PostScript printer filters, which almost all use
        ghostscript if necessary. Those should be configured during the
        original system installation or by your system administrator.
      </para>

          <title>Installation of CUPS printers</title>
          <para>
            If you are using CUPS, you do not need to configure .ini or
            registry entries, everything is autodetected.
          </para>
        </sect4>
        <sect4>
          <title>Installation of LPR /etc/printcap based printers</title>
          <para>
            If your system is not yet using CUPS, it probably uses LPRng
            or a LPR based system with configuration based on <filename>/etc/printcap</filename>.
          </para>
          <para>
            If it does, your printers in <filename>/etc/printcap</filename>
            are scanned with a heuristic whether they are PostScript capable
            printers and also configured mostly automatic.
          </para>
          <para>
            Since Wine cannot find out what type of printer this is, you
            need to specify a PPD file in the [ppd] section of
            <filename>~/.wine/config</filename>. Either use the shortcut
            name and make the entry look like:
          </para>
          <screen>
            [ppd]
            "ps1" = "/usr/lib/wine/ps1.ppd"
          </screen>
          <para>
            Or you can specify a generic PPD file that is to match for all
            of the remaining printers. A generic PPD file can be found in
            <filename>documentation/samples/generic.ppd</filename>.
          </para>
        </sect4>
        <sect4>
          <title>Installation of other printers</title>
          <para>
            You do not need to do this if the above 2 sections apply, only if
            you have a special printer.
          </para>
          <screen>
  Wine PostScript Driver=WINEPS,LPT1:
          </screen>
          <para>
            to the [devices] section and
          </para>
          <screen>
  Wine PostScript Driver=WINEPS,LPT1:,15,45
          </screen>
          <para>
            to the [PrinterPorts] section of <filename>win.ini</filename>,
            and to set it as the default printer also add
          </para>
          <screen>
  device = Wine PostScript Driver,WINEPS,LPT1:
          </screen>
          <para>
            to the [windows] section of <filename>win.ini</filename>.
          </para>
          <para>
            You also need to add certain entries to the registry.
            The easiest way to do this is to customise the PostScript
            driver contents of <filename>winedefault.reg</filename> (see below) and use the
            Winelib program <command>programs/regedit/regedit</command>.  For
            example, if you have installed the Wine source tree in
            <filename>/usr/src/wine</filename>, you could use the following
            series of commands:
            <itemizedlist>
              <listitem>
                <para>
                  <userinput>cp /usr/src/wine/winedefault.reg ~</userinput>
                </para>
              </listitem>
              <listitem>
                <para><userinput>vi ~/winedefault.reg</userinput></para>
              </listitem>
              <listitem>
                <para>
                  Edit the copy of <filename>winedefault.reg</filename> to suit your
                  PostScript printing requirements.
                  At a minimum, you must specify a PPD file for each printer.

          <para>
            You won't need Adobe Font Metric (AFM) files for the (type 1 PostScript)
            fonts that you wish to use any more.
            Wine now has this information built-in.
          </para>
          <para>
            You'll need a PPD file for your printer.  This describes
            certain characteristics of the printer such as which fonts are
            installed, how to select manual feed etc. Adobe has many of
            these on its website, have a look in
            <ulink url="ftp://ftp.adobe.com/pub/adobe/printerdrivers/win/all/">
            ftp://ftp.adobe.com/pub/adobe/printerdrivers/win/all/</ulink>.
            See above for information on configuring the driver to use this
            file.
          </para>
          <para>
            To enable colour printing you need to have the
            <literal>*ColorDevice</literal> entry in the PPD set to
            <literal>true</literal>, otherwise the driver will generate
            greyscale.
          </para>
          <para>
            Note that you need not set <literal>printer=on</literal> in
            the [wine] section of the wine config file, this
            enables printing via external printer drivers and does not
            affect the built-in PostScript driver.
          </para>

            Powerpoint2000 with some degree of success - you should be

              Driver does read PPD files, but ignores all constraints
              and doesn't let you specify whether you have optional
              extras such as envelope feeders. You will therefore find
              a larger than normal selection of input bins in the
              print setup dialog box. I've only really tested ppd
