* by the platforms printing system (typically PostScript,
* but on many platforms PDF may work too). See
* gtk_printer_accepts_pdf() and gtk_printer_accepts_ps().

* This is similar to gtk_print_job_set_source_file(),
* but takes expects an open file descriptor for the file,
* instead of a filename.
*
* Returns: %FALSE if an error occurred
*
* Since: 3.22
