#4 JGrid not supporting print

[Anonymous]

Using java.awt.print.Printable i wanted to print JGrid, but it is throwing ArrayIndex errors on JGrid cells. It is unable to paint JGrid. Coult you please tell me what i am doing wrong? I took the code to print swing components from the following site.

Thanks,
