I don't even know if this is pos开发者_StackOverflowsible 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.
Any thoughts?
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
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintException;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.print.attribute.standard.Copies;
import javax.print.event.PrintJobAdapter;
import javax.print.event.PrintJobEvent;
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));
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
Doc doc = new SimpleDoc(is, flavor, null);
DocPrintJob job = service.createPrintJob();
PrintJobWatcher pjw = new PrintJobWatcher(job);
job.print(doc, pras);
pjw.waitForDone();
is.close();
}
}
class PrintJobWatcher {
boolean done = false;
PrintJobWatcher(DocPrintJob job) {
job.addPrintJobListener(new PrintJobAdapter() {
public void printJobCanceled(PrintJobEvent pje) {
allDone();
}
public void printJobCompleted(PrintJobEvent pje) {
allDone();
}
public void printJobFailed(PrintJobEvent pje) {
allDone();
}
public void printJobNoMoreEvents(PrintJobEvent pje) {
allDone();
}
void allDone() {
synchronized (PrintJobWatcher.this) {
done = true;
System.out.println("Printing done ...");
PrintJobWatcher.this.notify();
}
}
});
}
public synchronized void waitForDone() {
try {
while (!done) {
wait();
}
} catch (InterruptedException e) {
}
}
}
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);
}
}
Following Man o War's and bmargulies' comments, take a look at the Java Tutorial Printing Lesson and the Java Print API.
