JComponent Print and Print Priview

[RAJEEV BAHL]

Following is listing in which jTextPane.paint(g2) is not being viewed/drawn. Though in same class PrintTextSingle g2.drawLine(0, 0, pageFormat.getWidth(), pageFormat.getHeight()) it is working fine. I am passing jTextPane from another class of same package to OutputView class. Thanks in advance.
