I use a customized AnyGantt chart. When I try to print it on a page A3 I get a mean issue with the background color. It becomes black. The Chart itself looks good.
When I try the same with examples from AnyChart.com the no black background appears. I don't see a difference.
The black background occurs with my PDF Creator, my real printer and if I save it as a picture.

If you add my source code as XML data you should see a nice Gantt diagram with damn printing problems!
Here is my source code:
