This problem occurs because your image is right for screen resolution, say, 72 dpi, but then printed at printer resolution, say, 288 dpi. Java uses the same 72 dpi coordinate system when printing, but it knows that the printer is at 4X higher resolution. So if you have a 72x72 image that displays as 1"x1" on the screen, Java does a 4X pixel replication of the 72x72 pixels to get 288x288 pixels so as to print the same 1"x1" on the page, which results in the blocky effect.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
