Printing BufferedImage
I have a Graphics2D plot on a 1272 pixel by 876 pixel BufferedImage that I display on the screen, and that takes about 45 minutes to make on a large set of data I am now working with. What should I use to get this BufferedImage printed before I throw it away?
Yes, print to paper on the printer the black and white plot that I have on the binary BufferedImage that I show on the screen. I suppose I could save the BufferedImage, but that still doesn't solve the problem of getting it to paper. I am plotting every point of almost a billion three dimensional vectors on three plots simultaneously on the screen BufferedImage. Of course many are on top of each other, but that is OK. I click on the plots to magnify the horizontal axis of the plots where I want to see it in more detail. I can print a (10.5*72)by(7.5*72) BufferedImage because the printer understands points. But that is a really rough picture. I would actually like to go the other way and make the BufferedImage (10.5*300)by(7.5*300) and render it (coarser?) for the screen, but print it at that fineness.

Print BufferedImage Externally Generated
Hi, I'm trying to build up a BufferedImage using its Graphics component, and then print that image using a Printable. The problem is that some of my operations on the graphics component seem to be lost, and when I print the image, a lot of it is clipped off around the borders. The code below shows the gist of what I'm doing.
// this method is in class A
foo(String text, Font font, B b, int x, int y) {
Graphics2D g2d = (Graphics2D) image.getGraphics();
g2d.setColor(Color.black); // this color gets lost when bar is called
g2d.setFont(font); // this font gets lost when bar is called
b.bar(text, x, y);
// this method is in class B
bar(String text, int x, int y) {
Graphics2D g2d = (Graphics2D) image.getGraphics();
g2d.drawString(text, x, y); // this does not get lost when the image is printed
// this is the print method for the Printable, the image is passed to the Printable
print(Graphics g, PageFormat pf, int pageIndex) {
if (pageIndex == 0) {
Graphics2D g2d = (Graphics2D)image.getGraphics();
g2d.translate(pf.getImageableX(), pf.getImageableY());
((Graphics2D)graphics).drawImage(image, null, 0, 0);
return Printable.PAGE_EXISTS;
} else {
return Printable.NO_SUCH_PAGE;
If I hardcode the color and font in the bar method, then the text actually comes out at the printer, but if x < 80 or x > 500, it doesn't get printed; same if y < 80 or y > 600 (these are approximate, I'm just estimating based on what I printed and where it got cut off). This leaves about a 1 inch margin around the printed text on the paper from the printer. Ultimately, I want to generate a document image using j2d and send that to the printer. Any help is greatly appreciated!
Thanks in advance!I just reposted my StandardPrint class today. This will let you either print a JLabel label on which you have installed the bufferedImage, or the BufferedImage itself by creating a SpecialPrint for it.

Printing problem with DocFlavor.SERVICE_FORMATTED RENDERABLE_IMAGE
Does anyone use javax.print for printing ?
I wanted to print the content of a JPanel, so a created a RenderableImage implementation, but my problem is that my EPSON Stylus Color C60 seems to not support this DocFlavor !
So I had to use a PRINTABLE, that is not a good thing since it is the same as java.awt.print.Printable : you should trick and workaround with scaled AffineTransform and disabled double-buffering when asking for the print.
So if anyone succeed in using javax.print to print BufferedImage, please tell me (tutorial,....)

KilwchI've worked hard to print a complex Gantt chart using both javax.print and java.awt.print packages. As I've to use only Postscript printers, I've implemented Printable and Pageable interfaces instead of RenderableImage. However, the results has been very good, including the zoom feature implemented using the Graphics2D' scale method.
Look at this user guide:

Hope this help -
Hello. I`m making a part of my program that will handle the printing. The problem is when I'm trying to print a image that does not fit on a PageFormat Imageable place. I want the image to resize so it fits the page.
Here is the method that does the resizing:
public BufferedImage scaleImg(BufferedImage bIn)
BufferedImage bOut = new BufferedImage(((int)(pageFormat.getImageableX())), ((int)(pageFormat.getImageableY())), BufferedImage.TYPE_INT_RGB);
AffineTransform tx = new AffineTransform();
tx.scale((double)(bIn.getWidth()/2), (pageFormat.getImageableY()));
AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_BILINEAR);
return op.filter(bIn, bOut);
}I think the problem is that I have to have a source image and a destination image, where the destination image is the problem. As you can see I'm resizing the destination image to the size of the PageFormat and setting the colortype. When I try to print with this code I get a little purplecolored square. :( Would be better If I didn't need a destination image and just get the image I have resized since I don't know anything about handling images in java.
Here is all of the code:

}Hi,
I just saw your code impleted for Scaling the BufferedImage. Even I am facing the related problem scaling the buffered Image to fit it in to size of single paper.
Initially I will take the screen capture of the image and will save it to some location. Then this image will be copied as BufferedImage to get the print.I am able to print the image but it prints in two sheets of paper.
Here is the code, Could you plz suggest me what changes it requires to implement the same. I am using jdk version of 1.3. This is very urgent.

Sending a BufferedImage to a printer.
I have a BufferedImage object that I want to send to a specific color printer. First, I send the BufferedImage to this method, which sets up the printer job.
public static void printOutChart(BufferedImage imageToPrint, int intCopies, String name) {
try {
//create a blank printJob
PrinterJob printJob = PrinterJob.getPrinterJob();
//make some attributes
AttributeSet attSet = new HashAttributeSet();
//this is the name of the printer I need to print to
attSet.add(new PrinterName("\\\\co-ps01\\CO-ResPlanHP5550", null));
//now find that printer
PrintService[] arrPrintServices = PrintServiceLookup.lookupPrintServices(null, attSet);
printJob.setPrintService(arrPrintServices[0]);
//okay, now set the correct number of copies
printJob.setCopies(intCopies);
//give it a name
printJob.setJobName(name);
//and finally, send the BufferedImage
printJob.setPrintable(new PrintInterface(imageToPrint));
printJob.print();
catch (Exception e) {
e.printStackTrace();
}Here's the code for the class that implements the Printable interface, that contains our BufferedImage:
final public class PrintInterface implements Printable {
BufferedImage chartToPrint;
PrintInterface(BufferedImage graph) {
chartToPrint = graph;
public int print(Graphics graphicsObj, PageFormat pageForm, int pageNo) {
if(pageNo > 0) {
return NO_SUCH_PAGE;
else {
Graphics2D obj2D = (Graphics2D)graphicsObj;
obj2D.translate(pageForm.getImageableX(), pageForm.getImageableY());
//print our BufferedImage to the printer page, with an identity transform
obj2D.drawRenderedImage(this.chartToPrint, new AffineTransform());
//print out a test string
obj2D.drawString("AuH2O 4 Prez", 300, 300);
return PAGE_EXISTS;
}When I print out the BufferedImage, all I get is the test string. Any ideas?Thanks for the reply. I think my code is solid, the problem is that I'm sending a huge image file, which is mostly white and doesn't fit on the page. In fact, none of the elements that the program draws to it before it sends it to the printer show up on the page. I'll either scale down my image or increase the resolution settings on the printer. If I can't get my stuff to work, I'll definitely implement that code you graciously linked to.

Resizing and Printing a bufferedImage.
I have a bufferedImage , and I was wondering if somebody could supply me with a method to resize it to the paper size and print it out with out asking the user anything. Except are you sure you want to print? This would be of great help!
Use AffineTransformOp.
Here is my code
//create an affinetransform (methods to set scale and rotation - I'm setting values directly)
AffineTransform image_at=new AffineTransform(Trm[0][0],Trm[1][0],Trm[0][1],(Trm[1][1]),0,0);
//make an imageOp
AffineTransformOp flip= new AffineTransformOp(image_at,hints);
//apply the opt to current image and put result in temp_image
temp_image=flip.filter(current_image,null);

Printing with BufferedImage and Text Quality
I am using PrinterJob to print text/graphics.
In my paint method, if we paint directly on the graphics handle using Graphics2D methods, the text quality is very good.
Our application has to manage a lot of data, and to handle the callabcks for the same page, we are painting to a BufferedImage, and then drawing the BufferedImage unto the graphics handle on the subsequent calls. The overhead to draw the page is significant, and this give us much better performance.
The PROBLEM IS, the quality of the text using the bufferedImage is like draft quality test, not the high resolution text we get when we paint directly on the supplied handle using the native drawing emthods every time.
Any idea how we can buffer the page image, and retain the text quality ?
In the paint we do:
m_Image = ((Graphics2D)pg).getDeviceConfiguration().createCompatibleImage(m_wPage,m_hPage);
m_Graphics = (Graphics2D) m_Image.getGraphics();Culd u share the fix if u found one

Creating and printing a BufferedImage with Robot class
I use class robot to create a bufferedImage of a screenCapture.
But all it keeps printing is a black box.
What am I missing here?

}Ok, day 4 of working on this. Dukes are still up for grabs.
I created a small pop up frame in the print method of the print Utilities class to display the buffered image, worked fine. So the problem seems to be in the drawImage()

Trouble printing an image that has BufferedImage composited onto it
I make a complex image by adding several BufferedImages that have been rotated. The result appears fine in a JComponent, but when I print the same image, the only part of the BufferedImage that comes through is the part located where the BufferedImage would have been if not rotated.
If the rotation is 90 degrees or more in either direction (that is, if no image will appear), I get the following error message:

ato.filter(bI,null);or
ato.filter(bI,bI);The printer graphics might be calling the later one. So you end up getting this result
the only part of the BufferedImage that comes through is the part located where the BufferedImage would have been if not rotatedTry changing the statement to

Print HTML file inside JEditorPane
Hi Guys,
I'm trying to print the contents of a JEditorPane - actually, a html file that I read and display in that component from the underlying file system. I've had the class that manages the JEditorPane implement Printable - the following is my print() implementation:
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex)
throws PrinterException {
if (pageIndex > 0) {
return (NO_SUCH_PAGE);
} else {
Graphics2D g2d = (Graphics2D) graphics;
g2d.translate(
pageFormat.getImageableX(),
pageFormat.getImageableY());
ivTextArea.paint(g2d);
return (PAGE_EXISTS);
}I've got another method that gets called when a print button is clicked:
class .... {
PrintJob pj;
PageFormat pf;
private void printMe() {
if (pj == null) {
pj = PrinterJob.getPrinterJob();
pf = pj.defaultPage();
pf.setOrientation(PageFormat.PORTRAIT);
pf = pj.pageDialog(pf);
pj.setPrintable(this, pf);
try {
pj.print();
} catch (PrinterException e) {
throw new RuntimeException(e);
}Clearly I'm doing smth wrong, since only a single page gets printed and moreover the formatting is awful [text gets cut instead of moving on the next line]. Can someone help?
Thanks much!if (pageIndex > 0) {
return (NO_SUCH_PAGE);This is why you only get a single page.
page gets printed and moreover the formatting is
awful [text gets cut instead of moving on the next
line]. Can someone help?Yeah. Your best bet is either to put the editorpane in a scrollpane and just print what's visible, OR, you can take the print graphics object, convert it into a graphics2D object, and call scale on that by comparing component.getWidth/height to PageFormat.getImageableWidth/Height
I'm attaching my StandardPrint class. It uses the pageable interface to carry the number of pages + page format as well. I'm not sure if I did the scaling here or not, but I've done it before so I know it works :-) Also, I've got methods for previewing the print, which can save a lot of paper.
Please feel free to have and use this class, but please do not change the package or portray this as your own work

Print images in PNG and BMP formats
I have converted images from xwd to bmp by using JAI. now I want to print them.
How can I print PNG and BMP Files? How can I read images in different formats and make them print.
Please help me !JAI follows the Java 2D printing model. All you need to do is to read your PNG, BMP images as RenderedImage, Renderable, or BufferedImage objects. To print an image, draw the image object on the printer's graphics context using one of drawImage(), drawRenderedImage(), and drawRenderableImage() methods of the Graphics2D class.
I have some sample code at http://www.geocities.com/larryhr/samplecode/samplecode.html. See the Printing section. JAIImagePrint.java should give you some indication as to how to print images read by the JAI codec. -

i am getting different output on different printers as well. I have classes defined as Printeable that draw forms, each form has 75 questions and they are all done using graphics2D some printer prints all the pages perfectly some other with different margin and on a laser printer i get only one box.
If it helps someone, for testing, i printed to file (.prn) and read the ouput through Red Titan it's free
it showed me one box out of 76
just the first one ????
possible solution that would help for margin
http://java.sun.com/developer/JDCTechTips/2004/tt0611.html
i used book and send printeable class and appended them into the book class
i am dying to solve this problem and wondering if there is better way for testing and how to make all pages
compatible for all printers. I want my program to send all forms to printer same format same size
is there any suggestion?? what am i doing wrong?
by the way
bk.append((Printable)componentsToBePrinted[i],pf);
componentsToBePrinted[] is an array of classes that implements Printeable and they all draw the forms correctly and sends to the printer. It is working mostly but i needed to work on alll printers no exceptions
I appreciate any help and i will issue all my duke starts im new to posting in the forum but i will give all my points for this tip
PLEASE HELPI want my program to send all forms to printer same format same size is there any suggestion??Produce a PDF... effectively delegating printing there-of to someone else. Problem solvered.
Your PDF options are (AFAIK) FOP or itext.

How to Print File as the same as picture/fax viewer ?
Hallo :
I wrote a program which can let the specified png file to be printed. (png file is about 17xx * 11xx, output to A4 paper)
The goal is the print result as the same as the windows built-in picture/fax viewer (by Full Page Fax Print Mode)
And I don't want the printer dialog to be appeared. So I tried to use java print service to achieve this goal.
Now I can print the file by printer.
But comparing to the result which is printed by the windows built-in picture fax viewer(use Full Page Fax Print Mode), my result looks like zoom in, not full page.
I tried some classes of javax.print.attribute.standard package, but no one worked.
So I tried to transform the image by myself. And I found a resource : [http://java.sun.com/products/java-media/2D/reference/faqs/index.html#Q_How_do_I_scale_an_image_to_fit]
It looks like what I wanted. But when I implemented the functionality according to that reference. The result is still the same, still zoom in...
I must said I am unfamiliar with java 2D. But this is a problem I must solve.
If the problem can be solved by only setting some classes of javax.print.attribute.standard, it's better.
But if can't be solved by that way, the transformation method is ok, too.
So does anyone can help me to solve this problem or pointed where I was wrong ? Thank you very much.

Edited by: oppstp on Aug 3, 2010 10:18 AMThanks for the reply.
Now my algorithm which I used is when the height of image is smaller than the height of A4 paper and the width of image
is larger than the width of A4 paper, I will rotate 90 degree of the image first, then I will scale the image.
Then I can get the approaching result when the width and height of the image are larger than the width and height of A4 paper.
But there was an additional error. That is when the width of image is larger than the width of A4 paper and
the height of image is smaller than the height of A4 paper. (like 17xx * 2xx).
Although the print result template is approaching the picture/fax viewer. But the print quality is so bad.
The texts are discontinue. I can see the white blank within the text. (the white line are the zone which printer doesn't print)
First I thought this problem might be DPI issue. But I don't know how to keep the DPI when rotating ?
(I dumped the rotate image, it rotates, but didn't keep the DPI value)
Does anyone know how to solve this strange problem ? Thanks a lot.

Thanks
RamRam,
I have had printing problems too a year and a half ago. I used all printing apis of java and I still find that it is something java lacks. Now basically you can try autosense. To check whether your printer is capable of printing the docflavor use this PrintServiceLookup.lookupPrintServices(flavor, aset); . If it lists the printer then he can print the document otherwise he can't. I guess that is why you get the error.
Regards,
Kevin -
Is it possible to print a JPanel from the application?
Hello,
Just a quick question: Is it possible to print a JPanel from your application? I have plotted a graph and I would like user to be able to print this with a click of a button (or similar)
Thanks very much for your help, its appreciated as always.
Harold ClementsIt is absolutely possible
Check out my StandardPrint class. Basically all you need to do is
(this is pseudocode. I don't remember the exact names of methods for all this stuff. Look it up if there's a problem)
PrinterJob pd = PrinterJob.createNewJob();
StandardPrint sp = new StandardPrint(yourComponent);
pd.setPageable(sp);
//if you want this
//pd.pageDialog();
pd.doPrint();You are welcome to have use and modify this class but please don't change the package or take credit for it as your own code.
