Question

我甚至不知道这是否可行，我对此表示高度怀疑，但如果可以的话，请告诉我如何？我只是想知道如何从打印机打印一些文本。

有什么想法吗？

Answer 1

这是更容易的事情。

import javax.swing.JTextPane;
import java.awt.print.PrinterException;

public class TestPrint {


    public static void main(String[] args) throws PrinterException {

        JTextPane textPane = new JTextPane();

        textPane.setText("test text string - Hello World! Are you there?");

        textPane.print();

    }
}

输出：弹出

Answer 2

您可以做的是写入文件，然后您可以使用Desktop类进行打印。有关桌面课程的详细信息，请转到here

here is the program


import java.awt.Desktop;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;


public class abc {


    public static void main(String[] args) throws IOException{

        BufferedWriter out = new BufferedWriter(new FileWriter("1.txt"));
        out.write("Hello this is a test");
        out.flush();
        out.close();

        File ff = new File("1.txt");

        Desktop desktop = Desktop.getDesktop();
      desktop.print(ff);

}

}
