纯java虚拟打印机

在项目中引入jpd.jar，示例代码如下：

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import java.awt.print.PrinterException;

/**
 * 打印示例
 */
public class PrintDemo implements Printable {
    private static final long serialVersionUID = 1L;
    /**
     * printable接口实现
     */
    public int print(Graphics g, PageFormat pageFormat, int pageIndex) throws PrinterException {
        if (pageIndex < 9) {
            g.setColor(Color.BLUE);
            g.setFont(new Font("Tahoma", Font.ITALIC, 10));
            g.drawString("http://www.hgsql.com", 20, 50);
            g.setColor(Color.ORANGE);
            g.setFont(new Font("Tahoma", Font.PLAIN, 100));           
            g.drawString("第" + (pageIndex + 1) + "页", 20, 150);
            return Printable.PAGE_EXISTS;
        } else {
            return Printable.NO_SUCH_PAGE;
        }
    }
}

import javax.print.PrintServiceLookup;
import javax.print.ServiceUI;
import javax.print.SimpleDoc;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
