draw_page

Emitted for every page that is printed.

The signal handler must render the page_nr's page onto the cairo context obtained from context using get_cairo_context.

static void
draw_page (GtkPrintOperation *operation,
					 GtkPrintContext	 *context,
					 gint							 page_nr,
					 gpointer					 user_data)
{
	cairo_t *cr;
	PangoLayout *layout;
	gdouble width, text_height;
	gint layout_height;
	PangoFontDescription *desc;
	
	cr = gtk_print_context_get_cairo_context (context);
	width = gtk_print_context_get_width (context);
	
	cairo_rectangle (cr, 0, 0, width, HEADER_HEIGHT);
	
	cairo_set_source_rgb (cr, 0.8, 0.8, 0.8);
	cairo_fill (cr);
	
	layout = gtk_print_context_create_pango_layout (context);
	
	desc = pango_font_description_from_string ("sans 14");
	pango_layout_set_font_description (layout, desc);
	pango_font_description_free (desc);
	
	pango_layout_set_text (layout, "some text", -1);
	pango_layout_set_width (layout, width * PANGO_SCALE);
	pango_layout_set_alignment (layout, PANGO_ALIGN_CENTER);
		 					
	pango_layout_get_size (layout, NULL, &layout_height);
	text_height = (gdouble)layout_height / PANGO_SCALE;
	
	cairo_move_to (cr, width / 2,	(HEADER_HEIGHT - text_height) / 2);
	pango_cairo_show_layout (cr, layout);
	
	g_object_unref (layout);
}

Use set_use_full_page and set_unit before starting the print operation to set up the transformation of the cairo context according to your needs.
