- * Instances of this class are used to print to a printer.

- * A <code>Printer</code> object may be constructed by providing
- * a <code>PrinterData</code> object which identifies the printer.
- * A <code>PrintDialog</code> presents a print dialog to the user
- * and returns an initialized instance of <code>PrinterData</code>.
- * Alternatively, calling <code>new Printer()</code> will construct a
- * printer object for the user's default printer.
- * </p><p>
- * Application code must explicitly invoke the <code>Printer.dispose()</code>
- * method to release the operating system resources managed by each instance
- * when those instances are no longer required.
