How would I go about printing text from a java program? (Java)

Question

I don\'t even know if this is possible and I highly doubt it is, but if you can, can you please tell me how? I just want to know how to print some text from a printer.

Answer 1

Following Man o War's and bmargulies' comments, take a look at the Java Tutorial Printing Lesson and the Java Print API.

(Primarily posting this answer in an attempt to either get this question some additional attention / competitive answers, or at the least, to simply remove this from the growing list of unanswered questions.)

import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintException;

public class PrintText {

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

    String defaultPrinter = 
      PrintServiceLookup.lookupDefaultPrintService().getName();
    System.out.println("Default printer: " + defaultPrinter);
    PrintService service = PrintServiceLookup.lookupDefaultPrintService();

    // prints the famous hello world! plus a form feed
    InputStream is = new ByteArrayInputStream("hello world!\f".getBytes("UTF8"));

    PrintRequestAttributeSet  pras = new HashPrintRequestAttributeSet();
    pras.add(new Copies(1));

What you can do is write to a file and then you can use Desktop class to print it. for more infomation on desktop class go 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);

}

}

Here is something that is even easier.

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();

    }
}

Output: popup
