Printing

JTable provides a simple API for printing tables. The easiest way to print out a table is to invoke JTable.print with no arguments:

try {
     if (! table.print()) {
         System.err.println("User cancelled printing");
     } 
 } catch (java.awt.print.PrinterException e) {
     System.err.format("Cannot print %s%n", e.getMessage()); 
 } 

Invoking print on a normal Swing application brings up a standard printing dialog box. (On a headless application, the table is simply printed.) The return value indicates whether the user went ahead with the print job or cancelled it. JTable.print can throw java.awt.print.PrinterException, which is a checked exception; that's why the above example uses a try ... catch.

JTable provides several overloads of print with various options. The following code from TablePrintDemo.java shows how to define a page header:

MessageFormat header = new MessageFormat("Page {0,number,integer}");

try {
    table.print(JTable.PrintMode.FIT_WIDTH, header, null); 
} catch (java.awt.print.PrinterException e) {
     System.err.format("Cannot print %s%n", e.getMessage()); 
}

For more sophisticated printing applications, use JTable.getPrintable to obtain a Printable object for the table. For more on Printable, refer to the Printing lesson in the 2D Graphics trail.
