+
+<para>Some specific features of &kdeprint; depend on the chosen print

+implemented there; remember, &kdeprint; is an intermediate layer between
+&kde; applications, and the print subsystem, but it's no replacement for
+any print subsystem by itself.  Such dependency may exist for another
+reason: that &kdeprint; has not yet implemented an interface to all the

+<title>&CUPS; Support: the Most Important Module in &kdeprint;</title>
+
+<para>&kdeprint; contains a module for &CUPS;.  &CUPS;, the
+<quote>Common &UNIX; Printing System</quote> (<ulink
+url="http://www.cups.org">http://www.cups.org/</ulink>), is the most
+advanced, powerful and flexible of all print subsystems on &UNIX; and
+other &UNIX;-like operating systems.  It is still quite new on the
+horizon, but is based on <acronym>IPP</acronym>, the Internet Printing
+Protocol, the newly emerging standard for the future of network
+printing. &CUPS; is clearly the print system of choice for Michael
+Goffioul, the principal &kdeprint; developer.</para>
+
+<para>Experienced &kde; users may already be familiar with Michael's
+utilities <application>qtcups</application> and
+<application>kups</application> (co-developed with Jean-Eric Cuendet).
+These were, up until now, the graphical
+&GUI; front ends for &CUPS; with a strong relation to &kde;.</para>
+
+<sect2>
+<title><application>qtcups</application> and
+<application>kups</application> &mdash; The Predecessors</title>
+
+<para>Both utilities are probably still widely used. For those
+not familiar with them,
+here are brief explanations.</para>
+
+<para><application>qtcups</application> was a graphical front end for
+the <command>lp</command> or <command>lpr</command> print commands as
+installed by &CUPS;. Using <application>qtcups</application> opened a
+dialog.  This dialog let you comfortably select your printer and the
+print job options. <application>qtcups</application>
+worked from the command line, or from
+within applications, when the application in question had a configurable
+print command.</para>
+
+<para><application>kups</application> was a graphical wrapper to do the
+administration tasks for your &CUPS; server, and the &CUPS; daemon at
+the heart of it.  You could add, delete, modify, configure, start, and
+stop printers.  You could cancel, delete, move, stop and restart print
+jobs, and you could change the settings of the daemon, start, stop, and
+restart it.</para>
+
+</sect2>
+
+<sect2>
+<title>&kdeprint; &mdash; The Heir</title>
+
+<para>The &CUPS; Module in &kdeprint; now contains all (and more)
+functions that were provided by <application>qtcups</application> and
+<application>kups</application> in former &kde; versions.</para>
+
+<para>Instead of <command>qtcups</command> you can now use the
+<command>kprinter</command> command.  And in place of
+<command>kups</command> you will probably use
+<command>kcmshell printers</command> from now on.
+</para>
+
+<para>The &kdeprint; module for &CUPS; also lets you fully administer
+the print subsystem, just like <application>kups</application> did
+before. It can start, stop and configure your &CUPS; daemon. It can also
+start, stop, add and delete <quote>printers</quote> (&ie; printer
+queues) and printer <quote>instances</quote>.  Printer instances are
+printer queues that point to the same physical output device but with a
+different default setting of print options.</para>
+
+</sect2>
+
+<sect2>
+<title>&kprinter; &mdash; Graphical Print Command</title>
+
+<para>&kdeprint;'s &CUPS; module gives you access to a <quote>graphical
+print command</quote>, like <application>qtcups</application> did
+before.</para>
+
+<para>Use &kprinter; in any application, even a non-&kde;
+application, that lets you configure your print command.  Examples of
+these are &Netscape; and <application>StarOffice</application>, but
+<emphasis>not</emphasis> most pre-&kde; 2.2 programs.</para>
+
+<para>A screenshot how to use the new <command>kprinter</command>
+print command instead of the old-fashioned <command>lpr</command>...
+Of course you need to have <command>kprinter</command> in your
+$<envar>PATH</envar>, or give the full path in the dialog; &eg;
+<userinput><filename>/opt/kde/bin/kprinter</filename></userinput>.
+&Netscape; will remember this and with further print jobs you will get
+the <command>kprinter</command> dialog to configure your printouts.</para>

+<option>/usr/share/doc/packages/cups/sam.pdf</option></userinput>.
+This will hand over the &CUPS; Software Administrator Manual to the
+<command>kprinter</command> dialog, which will then pop up with the
+default printer pre-selected.</para>
+
+<para>To pre-select a specific printer from the command line, use the
+<option>-d</option> option, &eg;:
+<userinput><command>kprinter</command> <option>-d
+DANKAcolorC2000</option>
+<option>/home/kurt/linuxtag2001-paper.ps</option></userinput>.  You
+can still de-select the printer <option>DANKAcolorC2000</option> and
+choose a different one.</para>
+
+<para> You <emphasis>cannot</emphasis> however call
+<userinput><command>kprinter</command></userinput> 
+without a print file and hope to open a file selection
+dialog box from the &kprinter; window. This is a feature that will be
+implemented only in the next version.</para>
+</note>
+
+<para>Using <command>kprinter</command> you are able to <quote>ring
+all the bells and blow all the whistles</quote> of your printer.  You
+will need a device-specific so-called &PPD; (&PostScript; Printer
+Description) to enable &CUPS; to make this nice tandem team do this
+for you.  Read more about this in <xref linkend="ppd-files"/>.</para>

+<title>Plans for Future Development</title>
+
+<para>What you have now is the first, already very feature-rich
+version of &kdeprint;. This version is, of course, fully usable for
+printing. You might even think that <quote>it was never so
+easy</quote> (not even back in the days when you had to use
+&Microsoft; &Windows;).</para>
+
+<para> In the future, &kdeprint; will become even better. It will do a
+better job of <quote>detecting</quote> your installed print subsystem
+itself. Already &kdeprint; is doing quite well in automatically
+sensing if you have &CUPS; on your system. But in many cases you will
+have to tell &kdeprint; what you are using, if you want to keep a
+legacy print system.</para>
+
+<para>The most important improvement in the near future will be a
+completion of the <application>LPRng</application> plugin.  This at
+present is still very basic.  It is restricted to the pure classical
+<acronym>LPD</acronym> part of
+<application>LPRng</application>.</para>
+
+<para>Also, you may be able to add printers directly from the print
+dialog to your system <quote>just in time</quote>, without going to
+&kcontrol; first.</para>
+
+<para>Some smaller improvements already planned are:</para>
+
+<itemizedlist>
+<listitem><para>add a file selection dialog from the &kprinter; window
+to allow combining of additional files to the present
+printjob</para></listitem> <listitem><para>add a
+<quote>history</quote> button to the
+<application>KJobViewer</application> window and also a column to show
+the number of pages &CUPS; calculates for the job.</para></listitem>
+</itemizedlist>
+
+<para>Finally, there will be an <quote>IO slave</quote> that will give
+you access to your print subsystem, via &konqueror; for example.  With
+this you will soon be able to browse your print subsystem from
+&konqueror; through a &URL; like shortcut such as
+<userinput>print://printers/printername</userinput>.  A KPart will add
+a virtual folder to the services section of the &konqueror; navigation
+panel, giving a nice integrated way to browse and manage your print
+system via the &URL; <userinput>print:/manager</userinput>.</para>
