我的应用程序中有一个非常简单的打印函数,可以打印Jtextpane的内容。我想将默认页面大小设置为A4,但在四处搜索后,我找到了许多涉及书籍和文档格式化程序等的方法,我希望尽可能简单

我目前的代码是:

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("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纸张大小,但不知道如何在JtextPane的.print属性中进行设置

谢谢你的帮助

你可以使用这种方法

在那里,您可以传递所需的PageFormat,在那里您可以指定所需的纸张大小/类型。

您可以使用这种方法

能帮上忙吗?有点,但我很难看到如何在我的代码中使用这个示例。我希望我可以保留大致相同的代码(因为它很简单),但用某种纸张大小替换其中一个空参数?可以帮助?有点,但我很难看到如何在代码中使用该示例。我希望我可以保留大致相同的代码(因为它很简单),但用某种纸张大小替换其中一个空参数?谢谢,这看起来像是我想要的那种简单的解决方案。我一试就会回来汇报。谢谢,这看起来像是我想要的那种简单的解决方案。我一试就回来报到。
