Question

我正在尝试使用PrintUtilities类打印JFrame：

package util;
import java.awt.*;
import javax.swing.*;
import java.awt.print.*;

public class PrintUtilities implements Printable {
  private Component componentToBePrinted;

  public static void printComponent(Component c) {
    new PrintUtilities(c).print();
  }

  public PrintUtilities(Component componentToBePrinted) {
    this.componentToBePrinted = componentToBePrinted;
  }

  public void print() {
    PrinterJob printJob = PrinterJob.getPrinterJob();
    printJob.setPrintable(this);
    if (printJob.printDialog())
      try {
        printJob.print();
      } catch(PrinterException pe) {
        System.out.println("Error printing: " + pe);
      }
  }

  public int print(Graphics g, PageFormat pf, int page) throws
                                                    PrinterException {
        if (page > 0) {
            return NO_SUCH_PAGE;
        }

        Graphics2D g2d = (Graphics2D)g;
        g2d.translate(pf.getImageableX(), pf.getImageableY());

        /* Print the entire visible contents of a java.awt.Frame */
        componentToBePrinted.printAll(g2d);

        return PAGE_EXISTS;
  }

  public static void disableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(false);
  }

  public static void enableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(true);
  }
}

这是JFrame的屏幕截图： http://img43.imageshack.us/img43/1980/48727815.jpg

这就是print（xps）的结果： http://img526.imageshack.us/img526/9954/47028546.jpg

我在这里做错了什么？

Answer 1

尝试打印到.xps时得到完全相同的结果，但是当我选择保存为Microsoft Office Document Image Writer（.tif）或直接打印到我的打印机时，它会正确打印。

您的目标是必须是.xps文件还是只是用于测试？
