<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.
</para>
<example>

<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.
