* SECTION:gtkprintunixdialog
* @Short_description: A print dialog
* @Title: GtkPrintUnixDialog
* @See_also: #GtkPageSetupUnixDialog, #GtkPrinter, #GtkPrintJob
*
* GtkPrintUnixDialog implements a print dialog for platforms
* which don't provide a native print dialog, like Unix. It can
* be used very much like any other GTK+ dialog, at the cost of
* the portability offered by the
* <link linkend="gtk3-High-level-Printing-API">high-level printing API</link>
*
* In order to print something with #GtkPrintUnixDialog, you need
* to use gtk_print_unix_dialog_get_selected_printer() to obtain
* a #GtkPrinter object and use it to construct a #GtkPrintJob using
* gtk_print_job_new().
*
* #GtkPrintUnixDialog uses the following response values:
* <variablelist>
* <varlistentry><term>%GTK_RESPONSE_OK</term>
* <listitem><para>for the "Print" button</para></listitem>
* </varlistentry>
* <varlistentry><term>%GTK_RESPONSE_APPLY</term>
* <listitem><para>for the "Preview" button</para></listitem>
* </varlistentry>
* <varlistentry><term>%GTK_RESPONSE_CANCEL</term>
* <listitem><para>for the "Cancel" button</para></listitem>
* </varlistentry>
* </variablelist>
*
* <!-- FIXME example here -->
*
* Printing support was added in GTK+ 2.10.
*
* <refsect2 id="GtkPrintUnixDialog-BUILDER-UI">
