Print system disabled. Use PDF instead (pending, needing fixing)
Postscript printers don't print when some text is shaded. Explanation : when text is shaded, java postscript output is in fact a large bitmap of the whole page (as postscript doesn't support transparency). Emulated postscript driver can deal with this, but it seems that various printers don't like it at all. Temporary solution : don't print directly.
