I'm trying to print a panel and the codes seems okay but when I click print and view it to pdf its only a blank page. I tried so many codes that can print panel but it doesn't print. Even I reinstall my NetBeans and install an updated jdk it won't work.
Blank page

You didn't dispose object g2 and use try catch block when you print as pdf. First you have to print the image as it is and then try to translate it.
Try this, i hope it would works.
OPSPrintPanel panel = new OPSPrintPanel();
//print the panel to pdf
Document document = new Document();
try {
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("C:\\temp\\test.pdf"));
document.open();
// PdfContentByte is an object containing the user positioned text and
// graphic contents of a page. It knows how to apply the proper font encoding.
PdfContentByte contentByte = writer.getDirectContent();
PdfTemplate template = contentByte.createTemplate(500, 500);
Graphics2D g2 = template.createGraphics(500, 500);
// First print the panel as it is and then try to translate it by removing comments
// g2.translate(pf.getImageableX(), pf.getImageableY());
panel.print(g2);
g2.dispose();
// Adds a template to this content.
contentByte.addTemplate(template, 30, 300);
} catch (Exception e)
{
e.printStackTrace();
}
finally
{
if(document.isOpen())
{
document.close();
}
}

Print JFrame in Java Application (Using Netbeans)

I'm trying to print the content of JFrame but, by looking at different tutorials, I still din't have any luck... Currently Parts of code for printing are
public class View_Check extends javax.swing.JFrame implements Printable{
JFrame frameToPrint;
public int print(Graphics g, PageFormat pf, int page) throws
PrinterException {
if (page > 0) {
return NO_SUCH_PAGE;
}
Graphics2D g2d = (Graphics2D) g;
g2d.translate(pf.getImageableX(), pf.getImageableY());
frameToPrint.printAll(g);
return PAGE_EXISTS;
}
and on the click of the button (jButton2)
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(this);
boolean ok = job.printDialog();
if (ok) {
try {
job.print();
} catch (PrinterException ex) {
}
}
}
Im Sure something is missing, but by trying to add "JFrame f" to View_Check didn't help... and new (View_Check(f)) either as f couldn't be found ant NetBeans was turning into a christmas tree with red lines
just in case here is a
public View_Check( Model_Customer cust) {
initComponents();
lblinfo1.setVisible(false);
customer = cust;
lblname.setText(customer.GetFName());
lblsurname.setText(customer.GetLName());
lblMake.setText(customer.GetMake());
lblModel.setText(customer.GetModel());
lblEngine.setText(customer.GetEngine());
lblRegistration.setText(customer.GetRegistration());
lblMileage.setText(customer.GetMileage());
String date = new SimpleDateFormat("dd-MM-yyyy").format(new Date());
lblDate.setText(date);
lblPostcode.setText(customer.GetPostcode());
lblNumber.setText(customer.GetNumber());
}
Changed frameToPrint.printAll(g); to this.printAll(g); and worked Like a charm :) Thanks for your help

try making the JFrame frameToPrint static
See if it solves the problem.

like:
//logo goes here
regn no:
regn date:
name:
phnno:
mail:
how to do it??

If you want to do printing with Java with any kind of formatting instead of plain text, you need to use javax.print. It is quite similar to the 2D graphics.
Have a look at the official tutorial at http://docs.oracle.com/javase/tutorial/2d/printing/ to learn how to do it.
From http://docs.oracle.com/javase/tutorial/displayCode.html?code=http://docs.oracle.com/javase/tutorial/2d/printing/examples/HelloWorldPrinter.java (untested):
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.print.*;
public class HelloWorldPrinter implements Printable, ActionListener {
public int print(Graphics g, PageFormat pf, int page) throws
PrinterException {
if (page > 0) { /* We have only one page, and 'page' is zero-based */
return NO_SUCH_PAGE;
}
/* User (0,0) is typically outside the imageable area, so we must
* translate by the X and Y values in the PageFormat to avoid clipping
*/
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pf.getImageableX(), pf.getImageableY());
/* Now we perform our rendering */
g.drawString("Hello world!", 100, 100);
/* tell the caller that this page is part of the printed document */
return PAGE_EXISTS;
}
public void actionPerformed(ActionEvent e) {
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(this);
boolean ok = job.printDialog();
if (ok) {
try {
job.print();
} catch (PrinterException ex) {
/* The job did not successfully complete */
}
}
}
public static void main(String args[]) {
UIManager.put("swing.boldMetal", Boolean.FALSE);
JFrame f = new JFrame("Hello World Printer");
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
});
JButton printButton = new JButton("Print Hello World");
printButton.addActionListener(new HelloWorldPrinter());
f.add("Center", printButton);
f.pack();
f.setVisible(true);
}
}

Adding a Print Button to JPanel [duplicate]

This question already has answers here:
How can I print a single JPanel's contents?
(3 answers)
Closed 9 years ago.
I have a JPanel, with some components like buttons, labels, table, etc.
What I want to do is to add a functionality (a jButton), that clicking on that button directs me to print the whole panel, along with labels and components.
Please help.

Just make a JButton that calls this code:
public void printComponent() {
PrinterJob pj = PrinterJob.getPrinterJob();
pj.setJobName(" Print Component ");
pj.setPrintable (new Printable() {
public int print(Graphics pg, PageFormat pf, int pageNum) {
if (pageNum > 0) return Printable.NO_SUCH_PAGE;
Graphics2D g2 = (Graphics2D) pg;
g2.translate(pf.getImageableX(), pf.getImageableY());
componenet_name.paint(g2);
return Printable.PAGE_EXISTS;
}
});
if (pj.printDialog() == false) return;
try {
pj.print();
} catch (PrinterException ex) {
// handle exception
}
}
(taken from: How can I print a single JPanel's contents?)

JAVA - Printing XPS without File Name/Location Pop-up

So im writing a java program for my dad to print out receipts and stuff. My original intention was to print out to his Receipt Printer some info regarding each transaction he made. However, the printer has some trouble printing what i send without clipping it to an extreme point.
My next idea, which worked out quite well, was to save the "receipt" into an XPS file and then print the XPS, which would not clip it and would make everything nice. Now, i can print into an XPS file using Microsoft's XPS Document Writer PrintService. The problem is, when i do it, it always pop's up a box asking for the file name and location to save it into.
Is there anyway to set it so as to not show that pop-up at all?
Current code:
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(this);
try {
job.print();
} catch (PrinterException ex) {
// The job did not successfully complete
}
-
#Override
public int print(Graphics g, PageFormat pf, int page) throws PrinterException {
String temp;
if (page > 0) { /* We have only one page, and 'page' is zero-based */
return NO_SUCH_PAGE;
}
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pf.getImageableX(), pf.getImageableY());
int lineSize=20;
Font testFont=new Font("Lucida Console", 0, 20);
g.setFont(testFont);
g.drawString(" Fatura/Recibo nº"+nmrRec+" ", 5, 20);
return PAGE_EXISTS;
}

You should be able to do it by setting the Destination attribute:
static void print(Printable printable, PrintService service)
throws PrintException,
IOException {
Path outputFile = Files.createTempFile(
Paths.get(System.getProperty("user.home")), null, ".xps");
Doc doc = new SimpleDoc(printable,
DocFlavor.SERVICE_FORMATTED.PRINTABLE, null);
PrintRequestAttributeSet attributes =
new HashPrintRequestAttributeSet();
attributes.add(new Destination(outputFile.toUri()));
DocPrintJob job = service.createPrintJob();
job.print(doc, attributes);
}

So i followed VGR's advice and i got it working. This was my final code, in case anyone runs into the same problem:
Date data = new Date(); //Data
DateFormat dataform = new SimpleDateFormat("dd-MM-yyyy"); //Data
PrintService service=getPrinterService("Microsoft XPS Document Writer");
if(service!=null){
try{
File outputFile = new File(dataform.format(data)+"-Recibo"+nmrRec+".xps");
Doc doc = new SimpleDoc(new myReceipt(), DocFlavor.SERVICE_FORMATTED.PRINTABLE, null);
PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
attributes.add(new Destination(outputFile.toURI()));
DocPrintJob job = service.createPrintJob();
job.print(doc, attributes);
} catch(Exception e){
System.out.println("kaboom"+e);
}
}
else{
System.out.println("XPS Printer not found");
}
And there's my receipt class:
class myReceipt implements Printable{
#Override
public int print(Graphics g, PageFormat pf, int page) throws PrinterException {
String temp;
if (page > 0) { /* We have only one page, and 'page' is zero-based */
return NO_SUCH_PAGE;
}
/* User (0,0) is typically outside the imageable area, so we must
* translate by the X and Y values in the PageFormat to avoid clipping
*/
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pf.getImageableX(), pf.getImageableY());
int lineSize=20;
Font testFont=new Font("Lucida Console", Font.BOLD, 20);
// font name, style (0 for Plain), font size
g.setFont(testFont);
int line=20;
g.drawString(" Fatura/Recibo nº"+nmrRec+" ", 5, line);
return PAGE_EXISTS;
}
}
