In two places in gtkprint code I see bare gettext() being used instead of dgettext().  Looks plain wrong to me:

In gtkprintoperation.c:

  if (string == NULL)
    string = g_strip_context (status_strs[status],
                              gettext (status_strs[status]));

In gtkpapersize.c:

  return g_strip_context (display_name, gettext (display_name));
