      <para>
        Printing in Wine can be done in one of two ways. Both of which are pretty alpha.

          <para>Use an external windows 3.1 printer driver.</para>
        </listitem>
        <listitem>
          <para>
            Use the builtin Wine Postscript driver (+ ghostscript to produce
            output for non-postscript printers).
          </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>

      <sect2>
        <title>External printer drivers</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 <filename>wine.conf</filename> (or
          <filename>~/.wine/config</filename>). 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>
      </sect2>

      <sect2>
        <title>Builtin Wine PostScript driver</title>
        <para>
          Enables printing of PostScript files via a driver built into Wine. See
          <filename>documentation/psdriver</filename> for installation
          instructions. The code for the PostScript driver is in
          <filename>graphics/psdrv</filename>.
        </para>
      </sect2>

      <sect2>
        <title>Spooling</title>
        <para>
          Spooling is rather primitive. The [spooler] section of
          <filename>wine.conf</filename> 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>

      <title>The Wine PostScript Driver</title>

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

      <para>
        When complete this will allow Wine to generate PostScript files without
        needing an external printer driver. It should be possible to print to a
        non PostScript printer by filtering the output through ghostscript.
      </para>

      <sect2>
        <title>Installation</title>
        <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>
        <para>
          To install it add
        </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>~/.wine/config</filename> and ???
          <emphasis>[sic]</emphasis>
        </para>
        <para>
          To run 32 bit apps (and 16 bit apps using the
          <literal>builtin</literal> commdlg) you also need to add certain
          entries to the registry.  The easiest way to do that at the moment is
          to use the winelib program <command>programs/regapi/regapi</command>
          with the file <filename>documentation/psdrv.reg</filename>.  To do this
          <command>cd</command> to <filename>programs/regapi/regapi</filename>
          and type <userinput>make</userinput> to actually make the program, then
          type <userinput>./regapi setValue
            &lt;../../documentation/psdrv.reg</userinput>.  You can obviously
          edit <filename>psdrv.reg</filename> to suit your requirements.
        </para>
        <para>
          You will need Adobe Font Metric (AFM) files for the (type 1 PostScript)
          fonts that you wish to use. You can get these from
          <ulink url="ftp://ftp.adobe.com/pub/adobe/type/win/all/afmfiles">
            ftp://ftp.adobe.com/pub/adobe/type/win/all/afmfiles </ulink>. The
          directories <filename>base17</filename> or <filename>base35</filename>
          are good places to start. Note that these are only the font metrics and
          not the fonts themselves. At the moment the driver does not download
          additional fonts, so you can only use fonts that are already present on
          the printer.
        </para>
        <para>
          Then create a [afmfiles] section in your
          <filename>wine.conf</filename> (or
          <filename>~/.wine/config</filename>) and add a line of the form
        </para>
        <screen>
"file&lt;n&gt;" = "/unix/path/name/filename.afm"
        </screen>
        <para>
          for each AFM file that you wish to use. [This might change in the future]
        </para>
        <para>
          You also require 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 also 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>. Create
          a [psdrv] section in your <filename>wine.conf</filename> (or
          <filename>~/.wine/config</filename>) and add the  following entry:
        </para>
        <screen>
"ppdfile" = "/somewhere/file.ppd"
        </screen>
        <para>
          By default, the driver will look for a file named
          <filename>default.ppd</filename> in the directory from which
          you started wine.
        </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 <filename>wine.conf</filename>, this
          enables printing via external printer drivers and does not
          affect wineps.
        </para>
        <para>
          If you're lucky you should now be able to produce PS files
          from Wine!
        </para>
        <para>
          I've tested it with win3.1 notepad/write, Winword6 and
          Origin4.0 and 32 bit apps such as win98 wordpad, Winword97,
          Powerpoint2000 with some degree of success - you should be
          able to get something out, it may not be in the right place.

              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
              parsing on the <filename>hp4m6_v1.ppd</filename> file.

              Notepad often starts text too far to the left depending
              on the margin settings. However the win3.1
              <filename>pscript.drv</filename> (under wine) also does
              this.
