打印JTextPane时的简单页面大小设置？

Question

我的应用程序中有一个非常简单的打印功能，可以打印Jtextpane的内容。我想将默认页面大小设置为A4，但是在搜索后我发现很多涉及书籍和文档formater等的方法，我希望尽可能简单。

我的代码目前是：

public void printy(){ 
    JTextPane jtp = new JTextPane(); 
    jtp.setBackground(Color.white); 
    try { 
      // open the file we have just decrypted 

       File myFile = new File(deletefile + "mx.txt"); 
       FileInputStream fIn = new FileInputStream(myFile); 
       BufferedReader myReader = new BufferedReader(
         new InputStreamReader(fIn)); 
       String aDataRow = ""; 
       String aBuffer = ""; 
       while ((aDataRow = myReader.readLine()) != null) { 
        aBuffer += aDataRow + "\n"; 
       } 

       String[] splitdata = aBuffer.split("`"); //recover the file and split it based on ` 
      String lines = ""; 
      for(String line : splitdata){ 
      lines = lines + line + System.getProperty("line.separator") + System.getProperty("line.separator"); 
      } 

       myReader.close(); 

       System.out.println(Arrays.toString(splitdata)); 
       System.out.println(lines); 

       jtp.setText(lines); 
       boolean show = true; 
       try { 
        //set the header and footer data here 
        MessageFormat headerFormat = new MessageFormat("HEADER HERE"); 
        MessageFormat footerFormat = new MessageFormat("FOOTER HERE"); 
        Paper A4 = new Paper(); 
        A4.setSize(595, 842); 
        A4.setImageableArea(43, 43, 509, 756); 


        jtp.print(headerFormat, footerFormat, show, null, null, show); 


       } catch (java.awt.print.PrinterException ex) { 
        ex.printStackTrace(); 
       } 
      } catch (Exception ez) { 
       System.out.println("error in array building"); 
      } 
} 
} 

我已经设置了A4纸大小，但不知道如何在对的JTextPane的属性.PRINT设置。

感谢您的帮助;

实际上，在尝试StanislavL提供的链接后，我在Oracle指南中发现了我认为是解决问题的更好方法，我使用的代码是;

public void printy(){ 
    JTextPane jtp = new JTextPane(); 
    jtp.setBackground(Color.white); 
    try { 
      // open the file we have just decrypted 

       File myFile = new File(deletefile + "mx.txt"); 
       FileInputStream fIn = new FileInputStream(myFile); 
       BufferedReader myReader = new BufferedReader(
         new InputStreamReader(fIn)); 
       String aDataRow = ""; 
       String aBuffer = ""; 
       while ((aDataRow = myReader.readLine()) != null) { 
        aBuffer += aDataRow + "\n"; 
       } 

       String[] splitdata = aBuffer.split("`"); //recover the file and split it based on ` 
      String lines = ""; 
      for(String line : splitdata){ 
      lines = lines + line + System.getProperty("line.separator") + System.getProperty("line.separator"); 
      } 

       myReader.close(); 

       System.out.println(Arrays.toString(splitdata)); 
       System.out.println(lines); 

       jtp.setText(lines); 
       boolean show = true; 
       try { 
        //set the header and footer data here 
        MessageFormat headerFormat = new MessageFormat("Your header here - {0}"); //sets the page number 
        MessageFormat footerFormat = new MessageFormat("Your footer here"); 

        PrintRequestAttributeSet attr_set = new HashPrintRequestAttributeSet(); 
        attr_set.add(MediaSizeName.ISO_A4); 
        attr_set.add(Sides.DUPLEX); 

        jtp.print(headerFormat, footerFormat, show, null, attr_set, show); 


       } catch (java.awt.print.PrinterException ex) { 
        ex.printStackTrace(); 
       } 

      } catch (Exception ez) { 
       System.out.println("error in array building"); 
      } 

} 
} 

希望这可以帮助其他人，不是说其完美的，但它确实工作得很好，默认情况下增加了复式。

您可以使用的方法http://java-sl.com/JEditorPanePrinter.html

在那里，你可以传递的PageFormat你需要，你可以指定所需的纸张尺寸/类型。
