There is no standard fork() wrapper in GTK+. If you want to use fork(), a
copy of "Advanced programming in the Unix environment" by Richard Stevens
might be helpful. If you don't care about the fact that your application
is not responsive during the printing, try using system() instead:

  /* print command. make this configurable, because my system uses
   * "lp -dlp5" ...
   */
  char print_cmd[] = "lpr -Phpljps";
  char buf[256];

  /* construct print command */
  g_snprintf(buf, 256, "%s %s", print_cmd, file_to_print);

  /* do it */
  system(buf);
