+    <title>OVERVIEW</title>
+    <para>
+      The "X Print Service" technology allows X rendering to devices such as
+      printers and fax.  Most of the service is available in the X11
+      technology stack as Xp, with the remainder in single toolkit stacks (e.g. DtPrint for CDE).
+      Modifications have also been made to the LessTif/Motif/Qt technology
+      stacks to support Xprint.
+    </para>
+    <para>
+      The Xp portion consists of:

+    <title>HOW THE X PRINT SERVICE WORKS</title>
+    <para>    
+      The X Print Service expands on the traditional X-Server and Xlib world
+      in four ways.
+
+      <orderedlist>
+        <listitem>
+          <para>
+            Most obvious is the use of "print ddx drivers" instead of
+            "video ddx drivers".  While a video ddx driver modifies pixels
+            in a video frame buffer, a print ddx driver generates "page
+            description language (PDL)" output (such as PCL, PDF or PostScript)
+            or sends the print rendering instructions to a platform-specific
+            print API (like Win32/GDI).
+          </para>
+          <para>
+            Once a print ddx driver generates PDL output, it can be sent to
+            a spooler such as <citerefentry><refentrytitle>lp</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+            or retrieved by the client (to implement functionality like "print-to-file").
+          </para>
+          <para>
+            Though not currently done, a single X-Server can support both
+            print and video ddx drivers.
+            <!-- FIXME: IBM/AIX people have integrated Xprt into their main Xserver (currently experimental) ... -->
+          </para>
+        </listitem>
+        <listitem>
+          <para>
+            Since printers support "paged" output, unlike video, a portion
+            of the Xp Extension supports APIs to delineate printed output.
+            For example, <function>XpStartPage</function> and <function>XpEndPage</function> tell the X-Server where
+            a physical page starts and ends in an otherwise continuous
+            stream of X rendering primitives.  Likewise, <function>XpStartJob</function> and
+            <function>XpEndJob</function> determine when a collection of pages starts and ends.
+            <function>XpEndJob</function> typically causes the generated PDL to be submitted to
+            a spooler, such as <citerefentry><refentrytitle>lp</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
+          </para>
+        </listitem>
+        <listitem>
+          <para>
+            Since printers have extensive capabilities, another portion of
+            the Xp Extension supports APIs to manipulate "print contexts".
+          </para>
+          <para>
+            Once a printer is selected using the Xp Extension API, a print
+            context to represent it can be created.  A print context
+            embodies the printer selected - it contains the printer's
+            default capabilities, selectable range of capabilities,
+            printer state, and generated output.  Some "attributes" within
+            the print context can be modified by the user, and the
+            X-Server and print ddx driver will react accordingly.  For
+            example, the attribute "content-orientation" can be set to
+            "landscape" or "portrait" (if the printer supports these 
+            values - which can be queried using the Xprint API as well).
+          </para>
+        </listitem>
+        <listitem>
+          <para>
+            Since printers can have "built in" fonts, the Xp Extension in
+            the X-Server works with the print ddx drivers to make
+            available (for printing only) additional fonts on a per print
+            context basis.
+          </para>
+          <para>
+            When a print context is created and set for a given printer,
+            the X font calls may be able to access additional printer
+            fonts.  To do this (typically), the X-Server must have access
+            to "printer metric files" (.pmf) that describe at minimum the
+            metrics of the built in fonts.

+
+  <refsect1>
+    <title>SERVER CONFIGURATION</title>
+    <para>
+      The X Print Server (Xprt) can read a number of configuration files which
+      control its behavior and support for printers.  Each vendor platform has
+      a default location for this information.  Xprt can also read the
+      environment variable <envar>XPCONFIGDIR</envar> to locate alternate configuration
+      directories.  Common settings include:
+
+      <simplelist type="vert">
+        <member>export XPCONFIGDIR=/X11/lib/X11/XpConfig/</member>
+        <member>export XPCONFIGDIR=/proj/x11/xc/programs/Xserver/XpConfig/</member>
+      </simplelist>
+    </para>
+    <para>
+      Xprt has many built-in defaults, and lacking any configuration files,
+      will immediately try to support all printers visible via <citerefentry><refentrytitle>lpstat</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
+    </para>
+    <para>
+      In order of importance for configuration by a system administrator, the
+      configuration files for a "C" locale are as follows (see <citerefentry><refentrytitle>Xprt</refentrytitle><manvolnum>__appmansuffix__</manvolnum></citerefentry> for more
+      details (including support for non-"C" locales)):

+          <listitem>
+            <para>
+              'Xprinters' is the top most configuration file.  It tells
+              Xprt which specific printer names (e.g.  mylaser) should
+              be supported, and whether <citerefentry><refentrytitle>lpstat</refentrytitle><manvolnum>1</manvolnum></citerefentry> or other commands
+              should be used to automatically supplement the list of
+              printers.

+          <listitem>
+            <para>
+              The 'printer' file maps printer names to model
+              configurations (see 'model-config' below).  For example,
+              "mylaser" could be mapped to a "HPDJ1600C", and all other
+              arbitrary printers could be mapped to a default, such as
+              "HPLJ4SI".  When depending on <citerefentry><refentrytitle>lpstat</refentrytitle><manvolnum>1</manvolnum></citerefentry> in the Xprinters
+              file, setting up defaults in 'printer' becomes all the
+              more important.

+              The 'document' file specifies the initial document values

+            <para>
+              The 'job' file specifies the initial job values for any
+              print jobs.  For example, "notification-profile" can be
+              set so that when a print job is successfully sent to a
+              printer, e-mail is sent to the user.

+              file also identifies the print ddx driver to be used.
+

+      Because the X Print Service is based on X, it can be easily distributed.

+        <listitem>
+          <para>
+            how many printers will be accessable through the printer

+            that one super-set version of them can be maintained and
+            distributed (e.g.  via NFS), and a per-machine or per-user
+            version of the `Xprinters' is all that is needed to have the

+          <para>
+            Global - in this model, the system administrator is choosing
+            to run the X Print Service on a *few* select machines with
+            appropriate printers configured, and allow clients access to
+            the global resource.  This can centralize the administration
+            of printers and configuration files, but may have to be

+      and offer limited capability to configure print options (e.g. number
+      of copies).  If the user wishes, they can select &lt;Setup...&gt;, which
+      will start a dtpdm capable of modifying additional print options.
