/**
 * SECTION:gtkprintjob
 * @Title: GtkPrintJob
 * @Short_description: Represents a print job
 *
 * A #GtkPrintJob object represents a job that is sent to a
 * printer. You only need to deal directly with print jobs if
 * you use the non-portable #GtkPrintUnixDialog API.
 *
 * Use gtk_print_job_get_surface() to obtain the cairo surface
 * onto which the pages must be drawn. Use gtk_print_job_send()
 * to send the finished job to the printer. If you don't use cairo
 * #GtkPrintJob also supports printing of manually generated postscript,
 * via gtk_print_job_set_source_file().
