High-level Printing API

<!-- ##### SECTION Long_Description ##### -->
<para>
GtkPrintOperation is the high-level, portable printing API. It looks 
a bit different than other GTK+ dialogs such as the #GtkFileChooser, 
since some platforms don't expose enough infrastructure to implement
a good print dialog. On such platforms, GtkPrintOperation uses the 
native print dialog. On platforms which do not provide a native 
print dialog, GTK+ uses its own, see #GtkPrintUnixDialog.
</para>

<para>
The typical way to use the high-level printing API is to create a 
#GtkPrintOperation object with gtk_print_operation_new() when the user 
selects to print. Then you set some properties on it, e.g. the page size, 
any #GtkPrintSettings from previous print operations, the number of pages, 
the current page, etc. 
</para>
<para>
Then you start the print operation by calling gtk_print_operation_run().
It will then show a dialog, let the user select a printer and options. 
When the user finished the dialog various signals will be emitted on the 
#GtkPrintOperation, the main one being ::draw-page, which you are supposed 
to catch and render the page on the provided #GtkPrintContext using Cairo.

<example>
<title>The high-level printing API</title>
<programlisting>
static GtkPrintSettings *settings = NULL;

static void
do_print (void)
{
  GtkPrintOperation *print;
  GtkPrintOperationResult res;

  print = gtk_print_operation_new (<!-- -->);

  if (settings != NULL) 
    gtk_print_operation_set_print_settings (print, settings);

  g_signal_connect (print, "begin_print", G_CALLBACK (begin_print), NULL);
  g_signal_connect (print, "draw_page", G_CALLBACK (draw_page), NULL);

  res = gtk_print_operation_run (print, GTK_WINDOW (main_window), NULL);

  if (res == GTK_PRINT_OPERATION_RESULT_APPLY)
    {
      if (settings != NULL)
        g_object_unref (settings);
      settings = g_object_ref (gtk_print_operation_get_print_settings (print));
    }

  g_object_unref (print);
}

</programlisting>
</example>

<para>
Printing support was added in GTK+ 2.10.
