Since `WPathGraphics` is used for Printing, backing store fails to print it and backing store uses newly created `SunGraphics2D` always. The proposed fix is to ignore `backingstore` graphics if passed on Graphics is different from `SunGraphics2D` which ensures the Image is painted on Window and also printed when required.

I guess this is not required

Also, please confirm JTable is  getting printed correctly either from existing testcases in javax/swing/JTable and from SwingSet2..
